Chartist.js for Ember-CLI Projects

Ember Observer Score

This is an ember-cli wrapper for Chartist. It allows you to render Chartist charts in your templates using components.

Important note

  • You should probably not use this addon as Chartist is not maintained.
  • Per the previous this package is also in maintenance mode only
  • Consider easing your upgrade burden by copying the component code to your application (along with the license) as this is MIT licensed.


  • Ember.js v3.20 or above
  • Ember CLI v3.20 or above
  • ember-auto-import v2 required
  • Node.js v12 or above


In an existing ember-cli project. Install with:

ember install ember-cli-chartist

In the template where you want the chart to appear:

<ChartistChart @type="line" @data={{model.chartData}} />
  • data is an optional attribute. Its value should be an object. Check the Chartist docs for expected data structure.
  • type is a required attribute. It can be any of the recognized chat types.

Where does the data come from?

The data can be specified in an Ember route or controller. In the example above it's coming from the model which is defined in the route.


import Route from '@ember/routing/route';

export default class ApplicationRoute extends Route {
  model() {
    return {
      chartData: {
        labels: ['Day1', 'Day2', 'Day3'],
        series: [
          [5, 4, 8],
          [10, 2, 7],
          [8, 3, 6],

Chart types

There are three types of charts; line, bar, and pie. The default is line. You can change the chart type using the type attribute.


<ChartistChart @type="bar" @data={{model.chartData}} />

Responsive scaling

Chartist charts scale up and down in size. They do so at specified ratios. You can change the ratio using the ratio attribute.


<ChartistChart @ratio="ct-golden-section" @data={{model.chartData}} />

See Chartist docs for the full list of ratios and info on how to create your own.

Chart configuration

Chartist charts have a whole bunch of cool configuration options. You can pass those to the chartist-chart components with the options attribute. You'll need to create the options object in a similar way as you do for the data attribute object.


<ChartistChart @options={{chartOptions}} @data={{model.chartData}} />


import Controller from '@ember/controller';

export default ApplicationController extends Controller {
  chartOptions = {
    showArea: true,
    lineSmooth: false,

    axisX: {
      showGrid: false

See the Chartist docs for all available config options. There's bunch of good-uns!

Responsive config

You can also configure your charts based on media queries. The same configuration options are available, but you provide them via the responsiveOptions attribute. They can be used in tandem with standard options.

<ChartistChart @responsiveOptions={{chartResOptions}} @data={{model.chartData}} />


import Controller from '@ember/controller';

export default ApplicationController extends Controller {
  chartResOptions = [
    ['screen and (min-width: 640px)', {
      showArea: true,
      lineSmooth: false,

      axisX: {
        showLabel: false

Other configuration

There are other ways to configure chartist-chart components that are specific to the addon.

updateOnData: By default, when the data associated with a chartist-chart is changed, the chart will be updated to reflect the data. That can be turned off by setting updateOnData to false. Note: If you use this option, you will have to manually draw and redraw the chart using Chartist methods.

<ChartistChart @updateOnData={{false}} />

Custom CSS

If you want to use custom CSS you can tell the addon to not include the compiled version.

In your app's ember-cli-build.js:

let app = new EmberApp({
  'ember-cli-chartist': {
    useCustomCSS: true,

If you use custom CSS, you'll likely want to import the Chartist Scss into your app's scss, you will need to install ember-cli-sass. You can then import the Chartist scss with:

In app.scss

@import 'chartist/chartist.scss';

you can also import the Chartist settings scss:

@import 'chartist/chartist-settings.scss';

For more on custom styles see the Chartist docs

Extending chartist-chart

Care has been taken to provide as many knobs and parameters as you'd need to NOT extend the <ChartistChart component. Pass in data you need. The component does yield its template above the chart.

Should you find yourself needing to extend the base class please open an issue.

Using Plugins

  1. Add the plugin of your choice to your dependencies, e.g. yarn add -D chartist-plugin-fill-donut
  2. In ember-cli-build.js import your plugin, e.g. app.import('node_modules/chartist-plugin-fill-donut/dist/chartist-plugin-fill-donut.js');
  3. In your chartOptions object add the plugin, e.g.
chartOptions = {
  plugins: [
      // config of plugin

Live examples

There is an example app included in this repo in /tests/dummy/. It contains examples of most of the functionality described above. To view those examples you'll need to clone this repo and start the Ember cli server.

git clone https://github.com/jherdman/ember-cli-chartist.git
cd ember-cli-chartist
ember serve

The example app will be running at http://localhost:4200

How do I Test My Chart?

Asserting on characteristics of your chart is kind of hard as it's an SVG rendering. Tools like Percy may be of help with ensuring your chart looks the way it should. We do have an issue open and are interested in pull requests to help with this matter.

Consider, however, that your chart may be difficult to read for people that are visually impaired. Consider implementing an accessible data table — these are vastly easier to make assertions on. Note that we do not provide tooling for this as it's out of scope for this library, and is probably too close to your business domain to meaningfully abstract.
