Contributing to Chart.js
========================
Contributions to Chart.js are welcome and encouraged, but please have a look through the guidelines in this document before raising an issue, or writing code for the project.
Using issues
------------
The [issue tracker](https://github.com/chartjs/Chart.js/issues) is the preferred channel for reporting bugs, requesting new features and submitting pull requests.
If you're suggesting a new chart type, please take a look at [writing new chart types](https://github.com/chartjs/Chart.js/blob/master/docs/07-Advanced.md#writing-new-chart-types) in the documentation or consider [creating a plugin](https://github.com/chartjs/Chart.js/blob/master/docs/07-Advanced.md#creating-plugins).
To keep the library lightweight for everyone, it's unlikely we'll add many more chart types to the core of Chart.js, but issues are a good medium to design and spec out how new chart types could work and look.
Please do not use issues for support requests. For help using Chart.js, please take a look at the [`chartjs`](http://stackoverflow.com/questions/tagged/chartjs) tag on Stack Overflow.
Reporting bugs
--------------
Well structured, detailed bug reports are hugely valuable for the project.
Guidlines for reporting bugs:
- Check the issue search to see if it has already been reported
- Isolate the problem to a simple test case
- Provide a demonstration of the problem on [JS Bin](http://jsbin.com) or similar
Please provide any additional details associated with the bug, if it's browser or screen density specific, or only happens with a certain configuration or data.
Local development
-----------------
Run `npm install` to install all the libraries, then run `gulp dev --test` to build and run tests as you make changes.
Pull requests
-------------
Clear, concise pull requests are excellent at continuing the project's community driven growth. But please review [these guidelines](https://github.com/blog/1943-how-to-write-the-perfect-pull-request) and the guidelines below before starting work on the project.
Be advised that **Chart.js 1.0.2 is in feature-complete status**. Pull requests adding new features to the 1.x branch will be disregarded.
Guidelines:
- Please create an issue first:
- For bugs, we can discuss the fixing approach
- For enhancements, we can discuss if it is within the project scope and avoid duplicate effort
- Please make changes to the files in [`/src`](https://github.com/chartjs/Chart.js/tree/master/src), not `Chart.js` or `Chart.min.js` in the repo root directory, this avoids merge conflicts
- Tabs for indentation, not spaces please
- If adding new functionality, please also update the relevant `.md` file in [`/docs`](https://github.com/chartjs/Chart.js/tree/master/docs)
- Please make your commits in logical sections with clear commit messages
Joining the project
-------------
- Active committers and contributors are invited to introduce yourself and request commit access to this project. Please send an email to hello@nickdownie.com or file an issue.
- We have a very active Slack community that you can join at https://chartjs-slack-automation.herokuapp.com. If you think you can help, we'd love to have you!
License
-------
By contributing your code, you agree to license your contribution under the [MIT license](https://github.com/chartjs/Chart.js/blob/master/LICENSE.md).

### Download Chart.js
To download a zip, go to [Chart.js on Github](https://github.com/chartjs/Chart.js) and choose the version that is right for your application.
* [Standard build](https://raw.githubusercontent.com/chartjs/Chart.js/master/dist/Chart.js) (~31kB gzipped)
* [Bundled with Moment.js](https://raw.githubusercontent.com/chartjs/Chart.js/master/dist/Chart.bundle.js) (~45kB gzipped)
* [CDN Versions](https://cdnjs.com/libraries/Chart.js)
To install via npm / bower:
```bash
npm install chart.js --save
```
```bash
bower install Chart.js --save
```
### Selecting the Correct Build
Chart.js provides two different builds that are available for your use. The `Chart.js` and `Chart.min.js` files include Chart.js and the accompanying color parsing library. If this version is used and you require the use of the time axis, [Moment.js](http://momentjs.com/) will need to be included before Chart.js.
The `Chart.bundle.js` and `Chart.bundle.min.js` builds include Moment.js in a single file. This version should be used if you require time axes and want a single file to include, select this version. Do not use this build if your application already includes Moment.js. If you do, Moment.js will be included twice, increasing the page load time and potentially introducing version issues.
### Installation
To import Chart.js using an old-school script tag:
```html
<script src="Chart.js"></script>
<script>
var myChart = new Chart({...})
</script>
```
To import Chart.js using an awesome module loader:
```javascript
// Using CommonJS
var Chart = require('src/chart.js')
var myChart = new Chart({...})
// ES6
import Chart from 'src/chart.js'
let myChart = new Chart({...})
// Using requirejs
require(['path/to/Chartjs'], function(Chart){
var myChart = new Chart({...})
})
```
### Creating a Chart
To create a chart, we need to instantiate the `Chart` class. To do this, we need to pass in the node, jQuery instance, or 2d context of the canvas of where we want to draw the chart. Here's an example.
```html
<canvas id="myChart" width="400" height="400"></canvas>
```
```javascript
// Any of the following formats may be used
var ctx = document.getElementById("myChart");
var ctx = document.getElementById("myChart").getContext("2d");
var ctx = $("#myChart");
```
Once you have the element or context, you're ready to instantiate a pre-defined chart-type or create your own!
The following example instantiates a bar chart showing the number of votes for different colors and the y-axis starting at 0.
```html
<canvas id="myChart" width="400" height="400"></canvas>
<script>
var ctx = document.getElementById("myChart");
var myChart = new Chart(ctx, {
type: 'bar',
data: {
labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
datasets: [{
label: '# of Votes',
data: [12, 19, 3, 5, 2, 3],
backgroundColor: [
'rgba(255, 99, 132, 0.2)',
'rgba(54, 162, 235, 0.2)',
'rgba(255, 206, 86, 0.2)',
'rgba(75, 192, 192, 0.2)',
'rgba(153, 102, 255, 0.2)',
'rgba(255, 159, 64, 0.2)'
],
borderColor: [
'rgba(255,99,132,1)',
'rgba(54, 162, 235, 1)',
'rgba(255, 206, 86, 1)',
'rgba(75, 192, 192, 1)',
'rgba(153, 102, 255, 1)',
'rgba(255, 159, 64, 1)'
],
borderWidth: 1
}]
},
options: {
scales: {
yAxes: [{
ticks: {
beginAtZero:true
}
}]
}
}
});
</script>
```
It's that easy to get started using Chart.js! From here you can explore the many options that can help you customise your charts with scales, tooltips, labels, colors, custom actions, and much more.

title: Chart Configuration
anchor: chart-configuration
---
Chart.js provides a number of options for changing the behaviour of created charts. These configuration options can be changed on a per chart basis by passing in an options object when creating the chart. Alternatively, the global configuration can be changed which will be used by all charts created after that point.
### Creating a Chart with Options
To create a chart with configuration options, simply pass an object containing your configuration to the constructor. In the example below, a line chart is created and configured to not be responsive.
```javascript
var chartInstance = new Chart(ctx, {
type: 'line',
data: data,
options: {
responsive: false
}
});
```
### Global Configuration
This concept was introduced in Chart.js 1.0 to keep configuration DRY, and allow for changing options globally across chart types, avoiding the need to specify options for each instance, or the default for a particular chart type.
Chart.js merges the options object passed to the chart with the global configuration using chart type defaults and scales defaults appropriately. This way you can be as specific as you would like in your individual chart configuration, while still changing the defaults for all chart types where applicable. The global general options are defined in `Chart.defaults.global`. The defaults for each chart type are discussed in the documentation for that chart type.
The following example would set the hover mode to 'single' for all charts where this was not overridden by the chart type defaults or the options passed to the constructor on creation.
```javascript
Chart.defaults.global.hover.mode = 'single';
// Hover mode is set to single because it was not overridden here
var chartInstanceHoverModeSingle = new Chart(ctx, {
type: 'line',
data: data,
});
// This chart would have the hover mode that was passed in
var chartInstanceDifferentHoverMode = new Chart(ctx, {
type: 'line',
data: data,
options: {
hover: {
// Overrides the global setting
mode: 'label'
}
}
})
```
#### Global Font Settings
There are 4 special global settings that can change all of the fonts on the chart. These options are in `Chart.defaults.global`.
Name | Type | Default | Description
--- | --- | --- | ---
defaultFontColor | Color | '#666' | Default font color for all text
defaultFontFamily | String | "'Helvetica Neue', 'Helvetica', 'Arial', sans-serif" | Default font family for all text
defaultFontSize | Number | 12 | Default font size (in px) for text. Does not apply to radialLinear scale point labels
defaultFontStyle | String | 'normal' | Default font style. Does not apply to tooltip title or footer. Does not apply to chart title
### Common Chart Configuration
The following options are applicable to all charts. The can be set on the [global configuration](#chart-configuration-global-configuration), or they can be passed to the chart constructor.
Name | Type | Default | Description
--- | --- | --- | ---
responsive | Boolean | true | Resizes when the canvas container does.
responsiveAnimationDuration | Number | 0 | Duration in milliseconds it takes to animate to new size after a resize event.
maintainAspectRatio | Boolean | true | Maintain the original canvas aspect ratio `(width / height)` when resizing
events | Array[String] | `["mousemove", "mouseout", "click", "touchstart", "touchmove", "touchend"]` | Events that the chart should listen to for tooltips and hovering
onClick | Function | null | Called if the event is of type 'mouseup' or 'click'. Called in the context of the chart and passed an array of active elements
legendCallback | Function | ` function (chart) { }` | Function to generate a legend. Receives the chart object to generate a legend from. Default implementation returns an HTML string.
### Title Configuration
The title configuration is passed into the `options.title` namespace. The global options for the chart title is defined in `Chart.defaults.global.title`.
Name | Type | Default | Description
--- | --- | --- | ---
display | Boolean | false | Display the title block
position | String | 'top' | Position of the title. Only 'top' or 'bottom' are currently allowed
fullWidth | Boolean | true | Marks that this box should take the full width of the canvas (pushing down other boxes)
fontSize | Number | 12 | Font size inherited from global configuration
fontFamily | String | "'Helvetica Neue', 'Helvetica', 'Arial', sans-serif" | Font family inherited from global configuration
fontColor | Color | "#666" | Font color inherited from global configuration
fontStyle | String | 'bold' | Font styling of the title.
padding | Number | 10 | Number of pixels to add above and below the title text
text | String | '' | Title text
#### Example Usage
The example below would enable a title of 'Custom Chart Title' on the chart that is created.
```javascript
var chartInstance = new Chart(ctx, {
type: 'line',
data: data,
options: {
title: {
display: true,
text: 'Custom Chart Title'
}
}
})
```
### Legend Configuration
The legend configuration is passed into the `options.legend` namespace. The global options for the chart legend is defined in `Chart.defaults.global.legend`.
Name | Type | Default | Description
--- | --- | --- | ---
display | Boolean | true | Is the legend displayed
position | String | 'top' | Position of the legend. Options are 'top' or 'bottom'
fullWidth | Boolean | true | Marks that this box should take the full width of the canvas (pushing down other boxes)
onClick | Function | `function(event, legendItem) {}` | A callback that is called when a click is registered on top of a label item
labels |Object|-| See the [Legend Label Configuration](#chart-configuration-legend-label-configuration) section below.
#### Legend Label Configuration
The legend label configuration is nested below the legend configuration using the `labels` key.
Name | Type | Default | Description
--- | --- | --- | ---
boxWidth | Number | 40 | Width of coloured box
fontSize | Number | 12 | Font size inherited from global configuration
fontStyle | String | "normal" | Font style inherited from global configuration
fontColor | Color | "#666" | Font color inherited from global configuration
fontFamily | String | "'Helvetica Neue', 'Helvetica', 'Arial', sans-serif" | Font family inherited from global configuration
padding | Number | 10 | Padding between rows of colored boxes
generateLabels: | Function | `function(chart) { }` | Generates legend items for each thing in the legend. Default implementation returns the text + styling for the color box. See [Legend Item](#chart-configuration-legend-item-interface) for details.
#### Legend Item Interface
Items passed to the legend `onClick` function are the ones returned from `labels.generateLabels`. These items must implement the following interface.
```javascript
{
// Label that will be displayed
text: String,
// Fill style of the legend box
fillStyle: Color,
// If true, this item represents a hidden dataset. Label will be rendered with a strike-through effect
hidden: Boolean,
// For box border. See https://developer.mozilla.org/en/docs/Web/API/CanvasRenderingContext2D/lineCap
lineCap: String,
// For box border. See https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/setLineDash
lineDash: Array[Number],
// For box border. See https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/lineDashOffset

```
#### Example
The following example will create a chart with the legend enabled and turn all of the text red in color.
```javascript
var chartInstance = new Chart(ctx, {
type: 'bar',
data: data,
options: {
legend: {
display: true,
labels: {
fontColor: 'rgb(255, 99, 132)'
}
}
}
});
```
### Tooltip Configuration
The title configuration is passed into the `options.tooltips` namespace. The global options for the chart tooltips is defined in `Chart.defaults.global.title`.
Name | Type | Default | Description
--- | --- | --- | ---
enabled | Boolean | true | Are tooltips
custom | Function | null | See [section](#chart-configuration-custom-tooltips) below
mode | String | 'single' | Sets which elements appear in the tooltip. Acceptable options are `'single'` or `'label'`. `single` highlights the closest element. `label` highlights elements in all datasets at the same `X` value.

multiKeyBackground | Color | "#fff" | Color to draw behind the colored boxes when multiple items are in the tooltip
callbacks | Object | | See the [callbacks section](#chart-configuration-tooltip-callbacks) below
#### Tooltip Callbacks
The tooltip label configuration is nested below the tooltip configuration using the `callbacks` key. The tooltip has the following callbacks for providing text. For all functions, 'this' will be the tooltip object created from the Chart.Tooltip constructor.
All functions are called with the same arguments: a [tooltip item](#chart-configuration-tooltip-item-interface) and the data object passed to the chart. All functions must return either a string or an array of strings. Arrays of strings are treated as multiple lines of text.
Callback | Arguments | Description
--- | --- | ---
beforeTitle | `Array[tooltipItem], data` | Text to render before the title
title | `Array[tooltipItem], data` | Text to render as the title
afterTitle | `Array[tooltipItem], data` | Text to render after the title
beforeBody | `Array[tooltipItem], data` | Text to render before the body section
beforeLabel | `tooltipItem, data` | Text to render before an individual label
label | `tooltipItem, data` | Text to render for an individual item in the tooltip
afterLabel | `tooltipItem, data` | Text to render after an individual label
afterBody | `Array[tooltipItem], data` | Text to render after the body section
beforeFooter | `Array[tooltipItem], data` | Text to render before the footer section
footer | `Array[tooltipItem], data` | Text to render as the footer
afterFooter | `Array[tooltipItem], data` | Text to render after the footer section
#### Tooltip Item Interface
The tooltip items passed to the tooltip callbacks implement the following interface.
```javascript
{
// X Value of the tooltip as a string
xLabel: String,
// Y value of the tooltip as a string
yLabel: String,
// Index of the dataset the item comes from
datasetIndex: Number,
// Index of this data item in the dataset
index: Number
}
```
### Hover Configuration
The hover configuration is passed into the `options.hover` namespace. The global hover configuration is at `Chart.defaults.global.hover`.
Name | Type | Default | Description
--- | --- | --- | ---
mode | String | 'single' | Sets which elements hover. Acceptable options are `'single'`, `'label'`, or `'dataset'`. `single` highlights the closest element. `label` highlights elements in all datasets at the same `X` value. `dataset` highlights the closest dataset.
animationDuration | Number | 400 | Duration in milliseconds it takes to animate hover style changes
onHover | Function | null | Called when any of the events fire. Called in the context of the chart and passed an array of active elements (bars, points, etc)
### Animation Configuration
The following animation options are available. The global options for are defined in `Chart.defaults.global.animation`.

onProgress | Function | none | Callback called on each step of an animation. Passed a single argument, an object, containing the chart instance and an object with details of the animation.
onComplete | Function | none | Callback called at the end of an animation. Passed the same arguments as `onProgress`
#### Animation Callbacks
The `onProgress` and `onComplete` callbacks are useful for synchronizing an external draw to the chart animation. The callback is passed an object that implements the following interface. An example usage of these callbacks can be found on [Github](https://github.com/chartjs/Chart.js/blob/master/samples/AnimationCallbacks/progress-bar.html). This sample displays a progress bar showing how far along the animation is.
```javscript
{
// Chart object
chartInstance,
// Contains details of the on-going animation
animationObject,
}
```
#### Animation Object
The animation object passed to the callbacks is of type `Chart.Animation`. The object has the following parameters.
```javascript
{
// Current Animation frame number
currentStep: Number,
// Number of animation frames
numSteps: Number,
// Animation easing to use
easing: String,
// Function that renders the chart
render: Function,
// User callback
onAnimationProgress: Function,
// User callback
onAnimationComplete: Function
}
```
### Element Configuration
The global options for elements are defined in `Chart.defaults.global.elements`.
Options can be configured for four different types of elements; arc, lines, points, and rectangles. When set, these options apply to all objects of that type unless specifically overridden by the configuration attached to a dataset.
#### Arc Configuration
Arcs are used in the polar area, doughnut and pie charts. They can be configured with the following options. The global arc options are stored in `Chart.defaults.global.elements.arc`.
Name | Type | Default | Description
--- | --- | --- | ---
backgroundColor | Color | 'rgba(0,0,0,0.1)' | Default fill color for arcs. Inherited from the global default
borderColor | Color | '#fff' | Default stroke color for arcs
borderWidth | Number | 2 | Default stroke width for arcs
#### Line Configuration

Name | Type | Default | Description
--- | --- | --- | ---
tension | Number | 0.4 | Default bezier curve tension. Set to `0` for no bezier curves.
backgroundColor | Color | 'rgba(0,0,0,0.1)' | Default line fill color
borderWidth | Number | 3 | Default line stroke width
borderColor | Color | 'rgba(0,0,0,0.1)' | Default line stroke color
borderCapStyle | String | 'butt' | Default line cap style. See [MDN](https://developer.mozilla.org/en/docs/Web/API/CanvasRenderingContext2D/lineCap)
borderDash | Array | `[]` | Default line dash. See [MDN](https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/setLineDash)

fill | Boolean | true | If true, the line is filled.
#### Point Configuration
Point elements are used to represent the points in a line chart or a bubble chart. The global point options are stored in `Chart.defaults.global.elements.point`.

borderSkipped | String | 'bottom' | Default skipped (excluded) border for rectangle. Can be one of `bottom`, `left`, `top`, `right`
### Colors
When supplying colors to Chart options, you can use a number of formats. You can specify the color as a string in hexadecimal, RGB, or HSL notations. If a color is needed, but not specified, Chart.js will use the global default color. This color is stored at `Chart.defaults.global.defaultColor`. It is initially set to 'rgb(0, 0, 0, 0.1)';
You can also pass a [CanvasGradient](https://developer.mozilla.org/en-US/docs/Web/API/CanvasGradient) object. You will need to create this before passing to the chart, but using it you can achieve some interesting effects.
The final option is to pass a [CanvasPattern](https://developer.mozilla.org/en-US/docs/Web/API/CanvasPattern) object. For example, if you wanted to fill a dataset with a pattern from an image you could do the following.
```javascript
var img = new Image();
img.src = 'https://example.com/my_image.png';
img.onload = function() {
var ctx = document.getElementById('canvas').getContext('2d');
var fillPattern = ctx.createPattern(img, 'repeat');
var chart = new Chart(ctx, {
data: {
labels: ['Item 1', 'Item 2', 'Item 3'],
datasets: [{
data: [10, 20, 30],
backgroundColor: fillPattern
}]
}
})
}
```

title: Scales
anchor: scales
---
Scales in v2.0 of Chart.js are significantly more powerful, but also different than those of v1.0.
* Multiple X & Y axes are supported.
* A built-in label auto-skip feature detects would-be overlapping ticks and labels and removes every nth label to keep things displaying normally.
* Scale titles are supported
* New scale types can be extended without writing an entirely new chart type
### Common Configuration
Every scale extends a core scale class with the following options:
Name | Type | Default | Description
--- | --- | --- | ---
type | String | Chart specific. | Type of scale being employed. Custom scales can be created and registered with a string key.

#### Creating Custom Tick Formats
The `callback` method may be used for advanced tick customization. In the following example, every label of the Y axis would be displayed in scientific notation.
If the callback returns `null` or `undefined` the associated grid line will be hidden.
```javascript
var chartInstance = new Chart(ctx, {
type: 'line',
data: data,
options: {
scales: {
yAxes: [{
ticks: {
// Create scientific notation labels
callback: function(value, index, values) {
return value.toExponential();
}
}
}]
}
}
});
```
### Category Scale
The category scale will be familiar to those who have used v1.0. Labels are drawn in from the labels array included in the chart data.
#### Configuration Options
The category scale has the following additional options that can be set.
Name | Type | Default | Description
--- | --- | --- | ---
ticks.min | String | - | The minimum item to display. Must be a value in the `labels` array
ticks.max | String | - | The maximum item to display. Must be a value in the `labels` array
gridLines.offsetGridLines | Boolean | - | If true, labels are shifted to be between grid lines. This is used in the bar chart.
### Linear Scale
The linear scale is use to chart numerical data. It can be placed on either the x or y axis. The scatter chart type automatically configures a line chart to use one of these scales for the x axis. As the name suggests, linear interpolation is used to determine where a value lies on the axis.
#### Configuration Options
The following options are provided by the linear scale. They are all located in the `ticks` sub options.
Name | Type | Default | Description
--- | --- | --- | ---
beginAtZero | Boolean | - | if true, scale will inclulde 0 if it is not already included.
min | Number | - | User defined minimum number for the scale, overrides minimum value from data.
max | Number | - | User defined maximum number for the scale, overrides maximum value from data.
maxTicksLimit | Number | 11 | Maximum number of ticks and gridlines to show. If not defined, it will limit to 11 ticks but will show all gridlines.
stepSize | Number | - | User defined fixed step size for the scale. If set, the scale ticks will be enumerated by multiple of stepSize, having one tick per increment. If not set, the ticks are labeled automatically using the nice numbers algorithm.
stepSize | Number | - | if defined, it can be used along with the min and the max to give a custom number of steps. See the example below.
suggestedMax | Number | - | User defined maximum number for the scale, overrides maximum value *except for if* it is lower than the maximum value.
suggestedMin | Number | - | User defined minimum number for the scale, overrides minimum value *except for if* it is higher than the minimum value.
#### Example Configuration
The following example creates a line chart with a vertical axis that goes from 0 to 5 in 0.5 sized steps.
```javascript
var chartInstance = new Chart(ctx, {
type: 'line',
data: data,
options: {
scales: {
yAxes: [{
ticks: {
max: 5,
min: 0,
stepSize: 0.5
}
}]
}
}
});
```
### Logarithmic Scale
The logarithmic scale is use to chart numerical data. It can be placed on either the x or y axis. As the name suggests, logarithmic interpolation is used to determine where a value lies on the axis.
#### Configuration Options
The following options are provided by the logarithmic scale. They are all located in the `ticks` sub options.
Name | Type | Default | Description
--- | --- | --- | ---
min | Number | - | User defined minimum number for the scale, overrides minimum value from data.
max | Number | - | User defined maximum number for the scale, overrides maximum value from data.
#### Example Configuration
The following example creates a chart with a logarithmic X axis that ranges from 1 to 1000.
```javascript
var chartInstance = new Chart(ctx, {
type: 'line',
data: data,
options: {
xAxes: [{
type: 'logarithmic',
position: 'bottom',
ticks: {
min: 1,
max: 1000
}
}]
}
})
```
### Time Scale
The time scale is used to display times and dates. It can only be placed on the X axis. When building its ticks, it will automatically calculate the most comfortable unit base on the size of the scale.
#### Configuration Options
The following options are provided by the logarithmic scale. They are all located in the `time` sub options.
Name | Type | Default | Description
--- | --- | --- | ---
displayFormats | Object | - | See [Display Formats](#scales-display-formats) section below.
isoWeekday | Boolean | false | If true and the unit is set to 'week', iso weekdays will be used.
max | [Time](#scales-date-formats) | - | If defined, this will override the data maximum
min | [Time](#scales-date-formats) | - | If defined, this will override the data minimum
parser | String or Function | - | If defined as a string, it is interpreted as a custom format to be used by moment to parse the date. If this is a function, it must return a moment.js object given the appropriate data value.
round | String | - | If defined, dates will be rounded to the start of this unit. See [Time Units](#scales-time-units) below for the allowed units.
tooltipFormat | String | '' | The moment js format string to use for the tooltip.
unit | String | - | If defined, will force the unit to be a certain type. See [Time Units](#scales-time-units) section below for details.
unitStepSize | Number | 1 | The number of units between grid lines.
#### Date Formats
When providing data for the time scale, Chart.js supports all of the formats that Moment.js accepts. See [Moment.js docs](http://momentjs.com/docs/#/parsing/) for details.
#### Display Formats
The following display formats are used to configure how different time units are formed into strings for the axis tick marks. See [moment.js](http://momentjs.com/docs/#/displaying/format/) for the allowable format strings.
Name | Default
--- | ---
millisecond | 'SSS [ms]'
second | 'h:mm:ss a'
minute | 'h:mm:ss a'
hour | 'MMM D, hA'
day | 'll'
week | 'll'
month | 'MMM YYYY'
quarter | '[Q]Q - YYYY'
year | 'YYYY'
For example, to set the display format for the 'quarter' unit to show the month and year, the following config would be passed to the chart constructor.
```javascript
var chartInstance = new Chart(ctx, {
type: 'line',
data: data,
options: {
scales: {
xAxes: [{
type: 'time',
time: {
displayFormats: {
quarter: 'MMM YYYY'
}
}
}]
}
}
})
```
#### Time Units
The following time measurements are supported. The names can be passed as strings to the `time.unit` config option to force a certain unit.
* millisecond
* second
* minute
* hour
* day
* week
* month
* quarter
* year
For example, to create a chart with a time scale that always displayed units per month, the following config could be used.
```javascript
var chartInstance = new Chart(ctx, {
type: 'line',
data: data,
options: {
scales: {
xAxes: [{
time: {
unit: 'month'
}
}]
}
}
})
```
### Radial Linear Scale
The radial linear scale is used specifically for the radar and polar are chart types. It overlays the chart area, rather than being positioned on one of the edges.
#### Configuration Options
The following additional configuration options are provided by the radial linear scale.
Name | Type | Default | Description
--- | --- | --- | ---
lineArc | Boolean | false | If true, circular arcs are used else straight lines are used. The former is used by the polar area chart and the latter by the radar chart
angleLines | Object | - | See the [Angle Lines](#scales-angle-line-options) section below for details.
pointLabels | Object | - | See the [Point Label](#scales-point-label) section below for details.
ticks | Object | - | See the Ticks table below for options.
#### Angle Line Options
The following options are used to configure angled lines that radiate from the center of the chart to the point labels. They can be found in the `angleLines` sub options. Note that these options only apply if `lineArc` is false.
Name | Type | Default | Description
--- | --- | --- | ---
display | Boolean | true | If true, angle lines are shown.
color | Color | 'rgba(0, 0, 0, 0.1)' | Color of angled lines
lineWidth | Number | 1 | Width of angled lines
#### Point Label Options
The following options are used to configure the point labels that are shown on the perimeter of the scale. They can be found in the `pointLabel` sub options. Note that these options only apply if `lineArc` is false.
Name | Type | Default | Description
--- | --- | --- | ---
callback | Function | - | Callback function to transform data label to axis label
fontColor | Color | '#666' | Font color
fontFamily | String | "'Helvetica Neue', 'Helvetica', 'Arial', sans-serif" | Font family to render

backdropPaddingX | Number | 2 | Horizontal padding of label backdrop
backdropPaddingY | Number | 2 | Vertical padding of label backdrop
maxTicksLimit | Number | 11 | Maximum number of ticks and gridlines to show. If not defined, it will limit to 11 ticks but will show all gridlines.
showLabelBackdrop | Boolean | true | If true, draw a background behind the tick labels
### Update Default Scale config
The default configuration for a scale can be easily changed using the scale service. Pass in a partial configuration that will be merged with the current scale default configuration.
For example, to set the minimum value of 0 for all linear scales, you would do the following. Any linear scales created after this time would now have a minimum of 0.
```
Chart.scaleService.updateScaleDefaults('linear', {
ticks: {
min: 0
}
})
```

### Introduction
A line chart is a way of plotting data points on a line. Often, it is used to show trend data, and the comparison of two data sets.
<div class="canvas-holder">
<canvas width="250" height="125"></canvas>
</div>
### Example Usage
```javascript
var myLineChart = new Chart(ctx, {
type: 'line',
data: data,
options: options
});
```
Alternatively a line chart can be created using syntax similar to the v1.0 syntax
```javascript
var myLineChart = Chart.Line(ctx, {
data: data,
options: options
});
```
### Data Structure
The following options can be included in a line chart dataset to configure options for that specific dataset.
All point* properties can be specified as an array. If these are set to an array value, the first value applies to the first point, the second value to the second point, and so on.
Property | Type | Usage
--- | --- | ---
data | See [data point](#line-chart-data-points) section | The data to plot in a line
label | `String` | The label for the dataset which appears in the legend and tooltips
xAxisID | `String` | The ID of the x axis to plot this dataset on
yAxisID | `String` | The ID of the y axis to plot this dataset on
fill | `Boolean` | If true, fill the area under the line
lineTension | `Number` | Bezier curve tension of the line. Set to 0 to draw straightlines. *Note* This was renamed from 'tension' but the old name still works.
backgroundColor | `Color` | The fill color under the line. See [Colors](#getting-started-colors)
borderWidth | `Number` | The width of the line in pixels
borderColor | `Color` | The color of the line.
borderCapStyle | `String` | Cap style of the line. See [MDN](https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/lineCap)
borderDash | `Array<Number>` | Length and spacing of dashes. See [MDN](https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/setLineDash)
borderDashOffset | `Number` | Offset for line dashes. See [MDN](https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/lineDashOffset)
borderJoinStyle | `String` | Line joint style. See [MDN](https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/lineJoin)
pointBorderColor | `Color or Array<Color>` | The border color for points.
pointBackgroundColor | `Color or Array<Color>` | The fill color for points
pointBorderWidth | `Number or Array<Number>` | The width of the point border in pixels
pointRadius | `Number or Array<Number>` | The radius of the point shape. If set to 0, nothing is rendered.
pointHoverRadius | `Number or Array<Number>` | The radius of the point when hovered
pointHitRadius | `Number or Array<Number>` | The pixel size of the non-displayed point that reacts to mouse events
pointHoverBackgroundColor | `Color or Array<Color>` | Point background color when hovered
pointHoverBorderColor | `Color or Array<Color>` | Point border color when hovered
pointHoverBorderWidth | `Number or Array<Number>` | Border width of point when hovered
pointStyle | `String, Array<String>, Image, Array<Image>` | The style of point. Options are 'circle', 'triangle', 'rect', 'rectRot', 'cross', 'crossRot', 'star', 'line', and 'dash'. If the option is an image, that image is drawn on the canvas using `drawImage`.
An example data object using these attributes is shown below.
```javascript
var data = {
labels: ["January", "February", "March", "April", "May", "June", "July"],
datasets: [
{
label: "My First dataset",
fill: false,
lineTension: 0.1,
backgroundColor: "rgba(75,192,192,0.4)",
borderColor: "rgba(75,192,192,1)",
borderCapStyle: 'butt',
borderDash: [],
borderDashOffset: 0.0,
borderJoinStyle: 'miter',
pointBorderColor: "rgba(75,192,192,1)",
pointBackgroundColor: "#fff",
pointBorderWidth: 1,
pointHoverRadius: 5,
pointHoverBackgroundColor: "rgba(75,192,192,1)",
pointHoverBorderColor: "rgba(220,220,220,1)",
pointHoverBorderWidth: 2,
pointRadius: 1,
pointHitRadius: 10,
data: [65, 59, 80, 81, 56, 55, 40],
}
]
};
```
The line chart usually requires an array of labels. This labels are shown on the X axis. There must be one label for each data point. More labels than datapoints are allowed, in which case the line ends at the last data point.
The data for line charts is broken up into an array of datasets. Each dataset has a colour for the fill, a colour for the line and colours for the points and strokes of the points. These colours are strings just like CSS. You can use RGBA, RGB, HEX or HSL notation.
The label key on each dataset is optional, and can be used when generating a scale for the chart.
### Data Points
The data passed to the chart can be passed in two formats. The most common method is to pass the data array as an array of numbers. In this case, the `data.labels` array must be specified and must contain a label for each point.
The alternate is used for sparse datasets. Data is specified using an object containing `x` and `y` properties. This is used for scatter charts as documented below.
### Scatter Line Charts
Scatter line charts can be created by changing the X axis to a linear axis. To use a scatter chart, data must be passed as objects containing X and Y properties. The example below creates a scatter chart with 3 points.
```javascript
var scatterChart = new Chart(ctx, {
type: 'line',
data: {
datasets: [{
label: 'Scatter Dataset',
data: [{
x: -10,
y: 0
}, {
x: 0,
y: 10
}, {
x: 10,
y: 5
}]
}]
},
options: {
scales: {
xAxes: [{
type: 'linear',
position: 'bottom'
}]
}
}
});
```
### Chart Options
These are the customisation options specific to Line charts. These options are merged with the [global chart configuration options](#chart-configuration-global-configuration), and form the options of the chart.
Name | Type | Default | Description
--- | --- | --- | ---
showLines | Boolean | true | If false, the lines between points are not drawn
You can override these for your `Chart` instance by passing a member `options` into the `Line` method.
For example, we could have a line chart display without an X axis by doing the following. The config merge is smart enough to handle arrays so that you do not need to specify all axis settings to change one thing.
```javascript
new Chart(ctx, {
type: 'line',
data: data,
options: {
scales: {
xAxes: [{
display: false
}]
}
}
});
```
We can also change these defaults values for each Line type that is created, this object is available at `Chart.defaults.line`.
### Stacked Charts
Stacked area charts can be created by setting the Y axis to a stacked configuration. The following example would have stacked lines.
```javascript
var stackedLine = new Chart(ctx, {
type: 'line',
data: data,
options: {
scales: {
yAxes: [{
stacked: true
}]
}
}
});
```

### Introduction
A bar chart is a way of showing data as bars.
It is sometimes used to show trend data, and the comparison of multiple data sets side by side.
<div class="canvas-holder">
<canvas width="250" height="125"></canvas>
</div>
### Example Usage
```javascript
var myBarChart = new Chart(ctx, {
type: 'bar',
data: data,
options: options
});
```
Or if you want horizontal bars.
```javascript
var myBarChart = new Chart(ctx, {
type: 'horizontalBar',
data: data,
options: options
});
```
### Data Structure
The following options can be included in a bar chart dataset to configure options for that specific dataset.
Some properties can be specified as an array. If these are set to an array value, the first value applies to the first bar, the second value to the second bar, and so on.
Property | Type | Usage
--- | --- | ---
data | `Array<Number>` | The data to plot as bars
label | `String` | The label for the dataset which appears in the legend and tooltips
xAxisID | `String` | The ID of the x axis to plot this dataset on
yAxisID | `String` | The ID of the y axis to plot this dataset on
backgroundColor | `Color or Array<Color>` | The fill color of the bars. See [Colors](#getting-started-colors)
borderColor | `Color or Array<Color>` | Bar border color
borderWidth | `Number or Array<Number>` | Border width of bar in pixels
borderSkipped | `String or Array<String>` | Which edge to skip drawing the border for. Options are 'bottom', 'left', 'top', and 'right'
hoverBackgroundColor | `Color or Array<Color>` | Bar background color when hovered
hoverBorderColor | `Color or Array<Color>` | Bar border color when hovered
hoverBorderWidth | `Number or Array<Number>` | Border width of bar when hovered
An example data object using these attributes is shown below.
```javascript
var data = {
labels: ["January", "February", "March", "April", "May", "June", "July"],
datasets: [
{
label: "My First dataset",
backgroundColor: "rgba(255,99,132,0.2)",
borderColor: "rgba(255,99,132,1)",
borderWidth: 1,
hoverBackgroundColor: "rgba(255,99,132,0.4)",
hoverBorderColor: "rgba(255,99,132,1)",
data: [65, 59, 80, 81, 56, 55, 40],
}
]
};
```
The bar chart has the a very similar data structure to the line chart, and has an array of datasets, each with colours and an array of data.
We have an array of labels too for display. In the example, we are showing the same data as the previous line chart example.
### Chart Options
These are the customisation options specific to Bar charts. These options are merged with the [global chart configuration options](#global-chart-configuration), and form the options of the chart.
The default options for bar chart are defined in `Chart.defaults.bar`.
Name | Type | Default | Description
--- |:---:| --- | ---
*hover*.mode | String | "label" | Label's hover mode. "label" is used since the x axis displays data by the index in the dataset.
scales | Object | - | -
*scales*.xAxes | Array | | The bar chart officially supports only 1 x-axis but uses an array to keep the API consistent. Use a scatter chart if you need multiple x axes.
*Options for xAxes* | | |
type | String | "Category" | As defined in [Scales](#scales-category-scale).
display | Boolean | true | If true, show the scale.
id | String | "x-axis-0" | Id of the axis so that data can bind to it
stacked | Boolean | false | If true, bars are stacked on the x-axis
categoryPercentage | Number | 0.8 | Percent (0-1) of the available width (the space between the gridlines for small datasets) for each data-point to use for the bars. [Read More](#bar-chart-barpercentage-vs-categorypercentage)
barPercentage | Number | 0.9 | Percent (0-1) of the available width each bar should be within the category percentage. 1.0 will take the whole category width and put the bars right next to each other. [Read More](#bar-chart-barpercentage-vs-categorypercentage)
gridLines | Object | [See Scales](#scales) |
*gridLines*.offsetGridLines | Boolean | true | If true, the bars for a particular data point fall between the grid lines. If false, the grid line will go right down the middle of the bars.
| | |
*scales*.yAxes | Array | `[{ type: "linear" }]` |
*Options for xAxes* | | |
type | String | "linear" | As defined in [Scales](#scales-linear-scale).
display | Boolean | true | If true, show the scale.
id | String | "y-axis-0" | Id of the axis so that data can bind to it.
stacked | Boolean | false | If true, bars are stacked on the y-axis
You can override these for your `Chart` instance by passing a second argument into the `Bar` method as an object with the keys you want to override.
For example, we could have a bar chart without a stroke on each bar by doing the following:
```javascript
new Chart(ctx, {
type: "bar",
data: data,
options: {
scales: {
xAxes: [{
stacked: true
}],
yAxes: [{
stacked: true
}]
}
}
}
});
// This will create a chart with all of the default options, merged from the global config,
// and the Bar chart defaults but this particular instance will have `stacked` set to true
// for both x and y axes.
```
We can also change these defaults values for each Bar type that is created, this object is available at `Chart.defaults.bar`. For horizontal bars, this object is available at `Chart.defaults.horizontalBar`.
The default options for horizontal bar charts are defined in `Chart.defaults.horizontalBar` and are same as those of the bar chart, but with `xAxes` and `yAxes` swapped and the following additional options.
Name | Type | Default | Description
--- |:---:| --- | ---
*Options for xAxes* | | |
position | String | "bottom" |
*Options for yAxes* | | |
position | String | "left" |
### barPercentage vs categoryPercentage
The following shows the relationship between the bar percentage option and the category percentage option.
```text
// categoryPercentage: 1.0
// barPercentage: 1.0
Bar: | 1.0 | 1.0 |

### Introduction
A radar chart is a way of showing multiple data points and the variation between them.
They are often useful for comparing the points of two or more different data sets.
<div class="canvas-holder">
<canvas width="250" height="125"></canvas>
</div>
### Example Usage
```javascript
var myRadarChart = new Chart(ctx, {
type: 'radar',
data: data,
options: options
});
```
### Data Structure
The following options can be included in a radar chart dataset to configure options for that specific dataset.
All point* properties can be specified as an array. If these are set to an array value, the first value applies to the first point, the second value to the second point, and so on.
Property | Type | Usage
--- | --- | ---
data | `Array<Number>` | The data to plot in a line
label | `String` | The label for the dataset which appears in the legend and tooltips
fill | `Boolean` | If true, fill the area under the line
lineTension | `Number` | Bezier curve tension of the line. Set to 0 to draw straightlines. *Note* This was renamed from 'tension' but the old name still works.
backgroundColor | `Color` | The fill color under the line. See [Colors](#getting-started-colors)
borderWidth | `Number` | The width of the line in pixels
borderColor | `Color` | The color of the line.
borderCapStyle | `String` | Cap style of the line. See [MDN](https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/lineCap)
borderDash | `Array<Number>` | Length and spacing of dashes. See [MDN](https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/setLineDash)
borderDashOffset | `Number` | Offset for line dashes. See [MDN](https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/lineDashOffset)
borderJoinStyle | `String` | Line joint style. See [MDN](https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/lineJoin)
pointBorderColor | `Color or Array<Color>` | The border color for points.
pointBackgroundColor | `Color or Array<Color>` | The fill color for points
pointBorderWidth | `Number or Array<Number>` | The width of the point border in pixels
pointRadius | `Number or Array<Number>` | The radius of the point shape. If set to 0, nothing is rendered.
pointHoverRadius | `Number or Array<Number>` | The radius of the point when hovered
hitRadius | `Number or Array<Number>` | The pixel size of the non-displayed point that reacts to mouse events
pointHoverBackgroundColor | `Color or Array<Color>` | Point background color when hovered
pointHoverBorderColor | `Color or Array<Color>` | Point border color when hovered
pointHoverBorderWidth | `Number or Array<Number>` | Border width of point when hovered
pointStyle | `String or Array<String>` | The style of point. Options include 'circle', 'triangle', 'rect', 'rectRot', 'cross', 'crossRot', 'star', 'line', and 'dash'
An example data object using these attributes is shown below.
```javascript
var data = {
labels: ["Eating", "Drinking", "Sleeping", "Designing", "Coding", "Cycling", "Running"],
datasets: [
{
label: "My First dataset",
backgroundColor: "rgba(179,181,198,0.2)",
borderColor: "rgba(179,181,198,1)",
pointBackgroundColor: "rgba(179,181,198,1)",
pointBorderColor: "#fff",
pointHoverBackgroundColor: "#fff",
pointHoverBorderColor: "rgba(179,181,198,1)",
data: [65, 59, 90, 81, 56, 55, 40]
},
{
label: "My Second dataset",
backgroundColor: "rgba(255,99,132,0.2)",
borderColor: "rgba(255,99,132,1)",
pointBackgroundColor: "rgba(255,99,132,1)",
pointBorderColor: "#fff",
pointHoverBackgroundColor: "#fff",
pointHoverBorderColor: "rgba(255,99,132,1)",
data: [28, 48, 40, 19, 96, 27, 100]
}
]
};
```
For a radar chart, to provide context of what each point means, we include an array of strings that show around each point in the chart.
For the radar chart data, we have an array of datasets. Each of these is an object, with a fill colour, a stroke colour, a colour for the fill of each point, and a colour for the stroke of each point. We also have an array of data values.
The label key on each dataset is optional, and can be used when generating a scale for the chart.
### Chart Options
These are the customisation options specific to Radar charts. These options are merged with the [global chart configuration options](#global-chart-configuration), and form the options of the chart.
The default options for radar chart are defined in `Chart.defaults.radar`.
Name | Type | Default | Description
--- | --- | --- | ---
scale | Object | [See Scales](#scales) and [Defaults for Radial Linear Scale](#scales-radial-linear-scale) | Options for the one scale used on the chart. Use this to style the ticks, labels, and grid lines.
*scale*.type | String |"radialLinear" | As defined in ["Radial Linear"](#scales-radial-linear-scale).
*elements*.line | Object | | Options for all line elements used on the chart, as defined in the global elements, duplicated here to show Radar chart specific defaults.
*elements.line*.lineTension | Number | 0 | Tension exhibited by lines when calculating splineCurve. Setting to 0 creates straight lines.
You can override these for your `Chart` instance by passing a second argument into the `Radar` method as an object with the keys you want to override.
For example, we could have a radar chart without a point for each on piece of data by doing the following:
```javascript
new Chart(ctx, {
type: "radar",
data: data,
options: {
scale: {
reverse: true,
ticks: {
beginAtZero: true
}
}
}
});
// This will create a chart with all of the default options, merged from the global config,
// and the Radar chart defaults but this particular instance's scale will be reversed as
// well as the ticks beginning at zero.
```
We can also change these defaults values for each Radar type that is created, this object is available at `Chart.defaults.radar`.

title: Polar Area Chart
anchor: polar-area-chart
---
### Introduction
Polar area charts are similar to pie charts, but each segment has the same angle - the radius of the segment differs depending on the value.
This type of chart is often useful when we want to show a comparison data similar to a pie chart, but also show a scale of values for context.
<div class="canvas-holder">
<canvas width="250" height="125"></canvas>
</div>
### Example Usage
```javascript
new Chart(ctx, {
data: data,
type: 'polarArea',
options: options
});
```
### Data Structure
The following options can be included in a polar area chart dataset to configure options for that specific dataset.
Some properties are specified as arrays. The first value applies to the first bar, the second value to the second bar, and so on.
Property | Type | Usage
--- | --- | ---
data | `Array<Number>` | The data to plot as bars
label | `String` | The label for the dataset which appears in the legend and tooltips
backgroundColor | `Array<Color>` | The fill color of the arcs. See [Colors](#getting-started-colors)
borderColor | `Array<Color>` | Arc border color
borderWidth | `Array<Number>` | Border width of arcs in pixels
hoverBackgroundColor | `Array<Color>` | Arc background color when hovered
hoverBorderColor | `Array<Color>` | Arc border color when hovered
hoverBorderWidth | `Array<Number>` | Border width of arc when hovered
An example data object using these attributes is shown below.
```javascript
var data = {
datasets: [{
data: [
11,
16,
7,
3,
14
],
backgroundColor: [
"#FF6384",
"#4BC0C0",
"#FFCE56",
"#E7E9ED",
"#36A2EB"
],
label: 'My dataset' // for legend
}],
labels: [
"Red",
"Green",
"Yellow",
"Grey",
"Blue"
]
};
```
As you can see, for the chart data you pass in an array of objects, with a value and a colour. The value attribute should be a number, while the color attribute should be a string. Similar to CSS, for this string you can use HEX notation, RGB, RGBA or HSL.
### Chart Options
These are the customisation options specific to Polar Area charts. These options are merged with the [global chart configuration options](#global-chart-configuration), and form the options of the chart.
Name | Type | Default | Description
--- | --- | --- | ---
scale | Object | [See Scales](#scales) and [Defaults for Radial Linear Scale](#scales-radial-linear-scale) | Options for the one scale used on the chart. Use this to style the ticks, labels, and grid.
*scale*.type | String |"radialLinear" | As defined in ["Radial Linear"](#scales-radial-linear-scale).
*scale*.lineArc | Boolean | true | When true, lines are circular.
*animation*.animateRotate | Boolean |true | If true, will animate the rotation of the chart.
*animation*.animateScale | Boolean | true | If true, will animate scaling the chart.
*legend*.*labels*.generateLabels | Function | `function(data) {} ` | Returns labels for each the legend
*legend*.onClick | Function | function(event, legendItem) {} ` | Handles clicking an individual legend item
legendCallback | Function | `function(chart) ` | Generates the HTML legend via calls to `generateLegend`
You can override these for your `Chart` instance by passing a second argument into the `PolarArea` method as an object with the keys you want to override.
For example, we could have a polar area chart with a black stroke on each segment like so:
```javascript
new Chart(ctx, {
data: data,
type: "polarArea",
options: {
elements: {
arc: {
borderColor: "#000000"
}
}
}
});
// This will create a chart with all of the default options, merged from the global config,
// and the PolarArea chart defaults but this particular instance will have `elements.arc.borderColor` set to `"#000000"`.
```
We can also change these defaults values for each PolarArea type that is created, this object is available at `Chart.defaults.polarArea`.

title: Pie & Doughnut Charts
anchor: doughnut-pie-chart
---
### Introduction
Pie and doughnut charts are probably the most commonly used chart there are. They are divided into segments, the arc of each segment shows the proportional value of each piece of data.
They are excellent at showing the relational proportions between data.
Pie and doughnut charts are effectively the same class in Chart.js, but have one different default value - their `cutoutPercentage`. This equates what percentage of the inner should be cut out. This defaults to `0` for pie charts, and `50` for doughnuts.
They are also registered under two aliases in the `Chart` core. Other than their different default value, and different alias, they are exactly the same.

<canvas width="250" height="125"></canvas>
</div>
<div class="canvas-holder half">
<canvas width="250" height="125"></canvas>
</div>
<br>
### Example Usage
```javascript
// For a pie chart
var myPieChart = new Chart(ctx,{
type: 'pie',
data: data,
options: options
});
```
```javascript
// And for a doughnut chart
var myDoughnutChart = new Chart(ctx, {
type: 'doughnut',
data: data,
options: options
});
```
### Data Structure
Property | Type | Usage
--- | --- | ---
data | `Array<Number>` | The data to plot as bars
label | `String` | The label for the dataset which appears in the legend and tooltips
backgroundColor | `Array<Color>` | The fill color of the arcs. See [Colors](#getting-started-colors)
borderColor | `Array<Color>` | Arc border color
borderWidth | `Array<Number>` | Border width of arcs in pixels
hoverBackgroundColor | `Array<Color>` | Arc background color when hovered
hoverBorderColor | `Array<Color>` | Arc border color when hovered
hoverBorderWidth | `Array<Number>` | Border width of arc when hovered
An example data object using these attributes is shown below.
```javascript
var data = {
labels: [
"Red",
"Blue",
"Yellow"
],
datasets: [
{
data: [300, 50, 100],
backgroundColor: [
"#FF6384",
"#36A2EB",
"#FFCE56"
],
hoverBackgroundColor: [
"#FF6384",
"#36A2EB",
"#FFCE56"
]
}]
};
```
For a pie chart, datasets need to contain an array of data points. The data points should be a number, Chart.js will total all of the numbers and calculate the relative proportion of each. You can also add an array of background colors. The color attributes should be a string. Similar to CSS, for this string you can use HEX notation, RGB, RGBA or HSL.
### Chart Options
These are the customisation options specific to Pie & Doughnut charts. These options are merged with the [global chart configuration options](#global-chart-configuration), and form the options of the chart.
Name | Type | Default | Description
--- | --- | --- | ---
cutoutPercentage | Number | 50 - for doughnut, 0 - for pie | The percentage of the chart that is cut out of the middle.
rotation | Number | -0.5 * Math.PI | Starting angle to draw arcs from
circumference | Number | 2 * Math.PI | Sweep to allow arcs to cover
*animation*.animateRotate | Boolean |true | If true, will animate the rotation of the chart.
*animation*.animateScale | Boolean | false | If true, will animate scaling the Doughnut from the centre.
*legend*.*labels*.generateLabels | Function | `function(chart) {} ` | Returns a label for each item to be displayed on the legend.
*legend*.onClick | Function | function(event, legendItem) {} ` | Handles clicking an individual legend item
You can override these for your `Chart` instance by passing a second argument into the `Doughnut` method as an object with the keys you want to override.
For example, we could have a doughnut chart that animates by scaling out from the centre like so:
```javascript
new Chart(ctx,{
type:"doughnut",
animation:{
animateScale:true
}
});
// This will create a chart with all of the default options, merged from the global config,
// and the Doughnut chart defaults but this particular instance will have `animateScale` set to `true`.
```
We can also change these default values for each Doughnut type that is created, this object is available at `Chart.defaults.doughnut`. Pie charts also have a clone of these defaults available to change at `Chart.defaults.pie`, with the only difference being `cutoutPercentage` being set to 0.

title: Bubble Chart
anchor: bubble-chart

### Introduction
A bubble chart is used to display three dimensions of data at the same time. The location of the bubble is determined by the first two dimensions and the corresponding horizontal and vertical axes. The third dimension is represented by the size of the individual bubbles.
<div class="canvas-holder">
<canvas width="250" height="125"></canvas>
</div>
<br>
### Example Usage
```javascript
// For a bubble chart
var myBubbleChart = new Chart(ctx,{
type: 'bubble',
data: data,
options: options
});
```
### Data Structure
Property | Type | Usage
--- | --- | ---
data | `Array<BubbleDataObject>` | The data to plot as bubbles. See [Data format](#bubble-chart-data-format)
label | `String` | The label for the dataset which appears in the legend and tooltips
backgroundColor | `Color Array<Color>` | The fill color of the bubbles.
borderColor | `Color or Array<Color>` | The stroke color of the bubbles.
borderWidth | `Number or Array<Number>` | The stroke width of bubble in pixels.
hoverBackgroundColor | `Color or Array<Color>` | The fill color of the bubbles when hovered.
hoverBorderColor | `Color or Array<Color>` | The stroke color of the bubbles when hovered.
hoverBorderWidth | `Number or Array<Number>` | The stroke width of the bubbles when hovered.
hoverRadius | `Number or Array<Number>` | Additional radius to add to data radius on hover.
An example data object using these attributes is shown below. This example creates a single dataset with 2 different bubbles.
```javascript
var data = {
datasets: [
{
label: 'First Dataset',
data: [
{
x: 20,
y: 30,
r: 15
},
{
x: 40,
y: 10,
r: 10
}
],
backgroundColor:"#FF6384",
hoverBackgroundColor: "#FF6384",
}]
};
```
### Data Object
Data for the bubble chart is passed in the form of an object. The object must implement the following interface. It is important to note that the radius property, `r` is **not** scaled by the chart. It is the raw radius in pixels of the bubble that is drawn on the canvas.
```javascript
{
// X Value
x: <Number>,
// Y Value
y: <Number>,
// Radius of bubble. This is not scaled.
r: <Number>
}
```
### Chart Options
The bubble chart has no unique configuration options. To configure options common to all of the bubbles, the point element options are used.
For example, to give all bubbles a 1px wide black border, the following options would be used.
```javascript
new Chart(ctx,{
type:"bubble",
options: {
elements: {
points: {
borderWidth: 1,
borderColor: 'rgb(0, 0, 0)'
}
}
}
});
```
We can also change the default values for the Bubble chart type. Doing so will give all bubble charts created after this point the new defaults. The default configuration for the bubble chart can be accessed at `Chart.defaults.bubble`.

### Prototype Methods
For each chart, there are a set of global prototype methods on the shared `ChartType` which you may find useful. These are available on all charts created with Chart.js, but for the examples, let's use a line chart we've made.
```javascript
// For example:
var myLineChart = new Chart(ctx, config);
```
#### .destroy()
Use this to destroy any chart instances that are created. This will clean up any references stored to the chart object within Chart.js, along with any associated event listeners attached by Chart.js.
This must be called before the canvas is reused for a new chart.
```javascript
// Destroys a specific chart instance
myLineChart.destroy();
```
#### .update(duration, lazy)
Triggers an update of the chart. This can be safely called after replacing the entire data object. This will update all scales, legends, and then re-render the chart.
```javascript
// duration is the time for the animation of the redraw in miliseconds
// lazy is a boolean. if true, the animation can be interupted by other animations
myLineChart.data.datasets[0].data[2] = 50; // Would update the first dataset's value of 'March' to be 50
myLineChart.update(); // Calling update now animates the position of March from 90 to 50.
```
#### .render(duration, lazy)
Triggers a redraw of all chart elements. Note, this does not update elements for new data. Use `.update()` in that case.
```javascript
// duration is the time for the animation of the redraw in miliseconds
// lazy is a boolean. if true, the animation can be interupted by other animations
myLineChart.render(duration, lazy);
```
#### .stop()
Use this to stop any current animation loop. This will pause the chart during any current animation frame. Call `.render()` to re-animate.
```javascript
// Stops the charts animation loop at its current frame
myLineChart.stop();
// => returns 'this' for chainability
```
#### .resize()
Use this to manually resize the canvas element. This is run each time the canvas container is resized, but you can call this method manually if you change the size of the canvas nodes container element.
```javascript
// Resizes & redraws to fill its container element
myLineChart.resize();
// => returns 'this' for chainability
```
#### .clear()
Will clear the chart canvas. Used extensively internally between animation frames, but you might find it useful.
```javascript
// Will clear the canvas that myLineChart is drawn on
myLineChart.clear();
// => returns 'this' for chainability
```
#### .toBase64Image()
This returns a base 64 encoded string of the chart in it's current state.
```javascript
myLineChart.toBase64Image();
// => returns png data url of the image on the canvas
```
#### .generateLegend()
Returns an HTML string of a legend for that chart. The legend is generated from the `legendCallback` in the options.
```javascript
myLineChart.generateLegend();
// => returns HTML string of a legend for this chart
```
#### .getElementAtEvent(e)
Calling `getElementAtEvent(event)` on your Chart instance passing an argument of an event, or jQuery event, will return the single element at the event position. If there are multiple items within range, only the first is returned
```javascript
myLineChart.getElementAtEvent(e);
// => returns the first element at the event point.
```
#### .getElementsAtEvent(e)
Looks for the element under the event point, then returns all elements at the same data index. This is used internally for 'label' mode highlighting.
Calling `getElementsAtEvent(event)` on your Chart instance passing an argument of an event, or jQuery event, will return the point elements that are at that the same position of that event.
```javascript
canvas.onclick = function(evt){
var activePoints = myLineChart.getElementsAtEvent(evt);
// => activePoints is an array of points on the canvas that are at the same position as the click event.
};
```
This functionality may be useful for implementing DOM based tooltips, or triggering custom behaviour in your application.
#### .getDatasetAtEvent(e)
Looks for the element under the event point, then returns all elements from that dataset. This is used internally for 'dataset' mode highlighting
```javascript
myLineChart.getDatasetAtEvent(e);
// => returns an array of elements
```
### External Tooltips
You can enable custom tooltips in the global or chart configuration like so:
```javascript
var myPieChart = new Chart(ctx, {
type: 'pie',
data: data,
options: {
tooltips: {
custom: function(tooltip) {
// tooltip will be false if tooltip is not visible or should be hidden
if (!tooltip) {
return;
}
// Otherwise, tooltip will be an object with all tooltip properties like:
// tooltip.caretSize
// tooltip.caretPadding
// tooltip.chart
// tooltip.cornerRadius
// tooltip.fillColor
// tooltip.font...
// tooltip.text
// tooltip.x
// tooltip.y
// etc...
}
}
}
});
```
See `sample/line-customTooltips.html` for examples on how to get started.
### Writing New Scale Types
Starting with Chart.js 2.0 scales can be individually extended. Scales should always derive from Chart.Scale.
```javascript
var MyScale = Chart.Scale.extend({
/* extensions ... */
});
// MyScale is now derived from Chart.Scale
```
Once you have created your scale class, you need to register it with the global chart object so that it can be used. A default config for the scale may be provided when registering the constructor. The first parameter to the register function is a string key that is used later to identify which scale type to use for a chart.
```javascript
Chart.scaleService.registerScaleType('myScale', MyScale, defaultConfigObject);
```
To use the new scale, simply pass in the string key to the config when creating a chart.
```javascript
var lineChart = new Chart(ctx, {
data: data,
type: 'line',
options: {
scales: {
yAxes: [{
type: 'myScale' // this is the same key that was passed to the registerScaleType function
}]
}
}
})
```
#### Scale Properties
Scale instances are given the following properties during the fitting process.
```javascript
{
left: Number, // left edge of the scale bounding box
right: Number, // right edge of the bounding box'
top: Number,
bottom: Number,
width: Number, // the same as right - left
height: Number, // the same as bottom - top
// Margin on each side. Like css, this is outside the bounding box.
margins: {
left: Number,
right: Number,
top: Number,
bottom: Number,
},
// Amount of padding on the inside of the bounding box (like CSS)
paddingLeft: Number,
paddingRight: Number,
paddingTop: Number,
paddingBottom: Number,
}
```
#### Scale Interface
To work with Chart.js, custom scale types must implement the following interface.
```javascript
{
// Determines the data limits. Should set this.min and this.max to be the data max/min
determineDataLimits: function() {},
// Generate tick marks. this.chart is the chart instance. The data object can be accessed as this.chart.data
// buildTicks() should create a ticks array on the axis instance, if you intend to use any of the implementations from the base class
buildTicks: function() {},
// Get the value to show for the data at the given index of the the given dataset, ie this.chart.data.datasets[datasetIndex].data[index]
getLabelForIndex: function(index, datasetIndex) {},
// Get the pixel (x coordinate for horizontal axis, y coordinate for vertical axis) for a given value
// @param index: index into the ticks array
// @param includeOffset: if true, get the pixel halway between the given tick and the next
getPixelForTick: function(index, includeOffset) {},
// Get the pixel (x coordinate for horizontal axis, y coordinate for vertical axis) for a given value
// @param value : the value to get the pixel for
// @param index : index into the data array of the value
// @param datasetIndex : index of the dataset the value comes from
// @param includeOffset : if true, get the pixel halway between the given tick and the next
getPixelForValue: function(value, index, datasetIndex, includeOffset) {}
// Get the value for a given pixel (x coordinate for horizontal axis, y coordinate for vertical axis)
// @param pixel : pixel value
getValueForPixel: function(pixel) {}
}
```
Optionally, the following methods may also be overwritten, but an implementation is already provided by the `Chart.Scale` base class.
```javascript
// Transform the ticks array of the scale instance into strings. The default implementation simply calls this.options.ticks.callback(numericalTick, index, ticks);
convertTicksToLabels: function() {},
// Determine how much the labels will rotate by. The default implementation will only rotate labels if the scale is horizontal.
calculateTickRotation: function() {},
// Fits the scale into the canvas.
// this.maxWidth and this.maxHeight will tell you the maximum dimensions the scale instance can be. Scales should endeavour to be as efficient as possible with canvas space.
// this.margins is the amount of space you have on either side of your scale that you may expand in to. This is used already for calculating the best label rotation
// You must set this.minSize to be the size of your scale. It must be an object containing 2 properties: width and height.
// You must set this.width to be the width and this.height to be the height of the scale
fit: function() {},
// Draws the scale onto the canvas. this.(left|right|top|bottom) will have been populated to tell you the area on the canvas to draw in
// @param chartArea : an object containing four properties: left, right, top, bottom. This is the rectangle that lines, bars, etc will be drawn in. It may be used, for example, to draw grid lines.
draw: function(chartArea) {},
```
The Core.Scale base class also has some utility functions that you may find useful.
```javascript
{
// Returns true if the scale instance is horizontal
isHorizontal: function() {},
// Get the correct value from the value from this.chart.data.datasets[x].data[]
// If dataValue is an object, returns .x or .y depending on the return of isHorizontal()
// If the value is undefined, returns NaN
// Otherwise returns the value.
// Note that in all cases, the returned value is not guaranteed to be a Number
getRightValue: function(dataValue) {},
}
```
### Writing New Chart Types
Chart.js 2.0 introduces the concept of controllers for each dataset. Like scales, new controllers can be written as needed.
```javascript
Chart.controllers.MyType = Chart.DatasetController.extend({
});
// Now we can create a new instance of our chart, using the Chart.js API
new Chart(ctx, {
// this is the string the constructor was registered at, ie Chart.controllers.MyType
type: 'MyType',
data: data,
options: options
});
```
#### Dataset Controller Interface
Dataset controllers must implement the following interface.
```javascript
{
// Create elements for each piece of data in the dataset. Store elements in an array on the dataset as dataset.metaData
addElements: function() {},
// Create a single element for the data at the given index and reset its state
addElementAndReset: function(index) {},
// Draw the representation of the dataset
// @param ease : if specified, this number represents how far to transition elements. See the implementation of draw() in any of the provided controllers to see how this should be used
draw: function(ease) {},
// Remove hover styling from the given element
removeHoverStyle: function(element) {},
// Add hover styling to the given element
setHoverStyle: function(element) {},
// Update the elements in response to new data
// @param reset : if true, put the elements into a reset state so they can animate to their final values
update: function(reset) {},
}
```
The following methods may optionally be overridden by derived dataset controllers
```javascript
{
// Initializes the controller
initialize: function(chart, datasetIndex) {},
// Ensures that the dataset represented by this controller is linked to a scale. Overridden to helpers.noop in the polar area and doughnut controllers as these
// chart types using a single scale
linkScales: function() {},
// Called by the main chart controller when an update is triggered. The default implementation handles the number of data points changing and creating elements appropriately.
buildOrUpdateElements: function() {}
}
```
### Extending Existing Chart Types
Extending or replacing an existing controller type is easy. Simply replace the constructor for one of the built in types with your own.
The built in controller types are:
* `Chart.controllers.line`
* `Chart.controllers.bar`
* `Chart.controllers.radar`
* `Chart.controllers.doughnut`
* `Chart.controllers.polarArea`
* `Chart.controllers.bubble`
#### Bar Controller
The bar controller has a special property that you should be aware of. To correctly calculate the width of a bar, the controller must determine the number of datasets that map to bars. To do this, the bar controller attaches a property `bar` to the dataset during initialization. If you are creating a replacement or updated bar controller, you should do the same. This will ensure that charts with regular bars and your new derived bars will work seamlessly.
### Creating Plugins
Starting with v2.1.0, you can create plugins for chart.js. To register your plugin, simply call `Chart.pluginService.register` and pass your plugin in.
Plugins will be called at the following times
* Start of initialization
* End of initialization
* Start of update
* After the chart scales have calculated
* End of update (before render occurs)
* Start of draw
* End of draw
* Before an animation is started
Plugins should derive from Chart.PluginBase and implement the following interface
```javascript
{
beforeInit: function(chartInstance) { },
afterInit: function(chartInstance) { },
beforeUpdate: function(chartInstance) { },
afterScaleUpdate: function(chartInstance) { }
afterUpdate: function(chartInstance) { },
// This is called at the start of a render. It is only called once, even if the animation will run for a number of frames. Use beforeDraw or afterDraw
// to do something on each animation frame
beforeRender: function(chartInstance) { },
// Easing is for animation
beforeDraw: function(chartInstance, easing) { },
afterDraw: function(chartInstance, easing) { }
destroy: function(chartInstance) { }
}
```
### Building Chart.js
Chart.js uses <a href="http://gulpjs.com/" target="_blank">gulp</a> to build the library into a single JavaScript file.
Firstly, we need to ensure development dependencies are installed. With node and npm installed, after cloning the Chart.js repo to a local directory, and navigating to that directory in the command line, we can run the following:
```bash
npm install
npm install -g gulp
```
This will install the local development dependencies for Chart.js, along with a CLI for the JavaScript task runner <a href="http://gulpjs.com/" target="_blank">gulp</a>.
Now, we can run the `gulp build` task.
```bash
gulp build
```

### Previous versions
Please note - documentation for previous versions are available on the GitHub repo. Version 1.x may continue to receive updates for bug fixes or high priority items.
- [1.x Documentation](https://github.com/chartjs/Chart.js/tree/v1.1.1/docs)
### Browser support
Chart.js offers support for all browsers where canvas is supported.
Browser support for the canvas element is available in all modern & major mobile browsers <a href="http://caniuse.com/#feat=canvas" target="_blank">(http://caniuse.com/#feat=canvas)</a>.
Thanks to <a href="https://browserstack.com" target="_blank">BrowserStack</a> for allowing our team to test on thousands of browsers.
### Bugs & issues
Please report these on the GitHub page - at <a href="https://github.com/chartjs/Chart.js" target="_blank">github.com/chartjs/Chart.js</a>. If you could include a link to a simple <a href="http://jsbin.com/" target="_blank">jsbin</a> or similar to demonstrate the issue, that'd be really helpful.
### Contributing
New contributions to the library are welcome, just a couple of guidelines:
- Tabs for indentation, not spaces please.
- Please ensure you're changing the individual files in `/src`, not the concatenated output in the `Chart.js` file in the root of the repo.
- Please check that your code will pass `jshint` code standards, `gulp jshint` will run this for you.
- Please keep pull requests concise, and document new functionality in the relevant `.md` file.
- Consider whether your changes are useful for all users, or if creating a Chart.js extension would be more appropriate.
### License
Chart.js is open source and available under the <a href="http://opensource.org/licenses/MIT" target="_blank">MIT license</a>.
