ember-cli-chartist

Chartist.js for Ember-CLI Projects

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

Setup

In an existing ember-cli project. Install with:

npm install ember-cli-chartist --save-dev

In the template where you want the chart to appear:

{{chartist-chart data=model.chartData}}

The data attribute is the only required attribute. It's value should be an object. Check the Chartist docs for expected data structure.

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.

/app/routes/application.js

import Ember from 'ember';

export default Ember.Route.extend({
  model: function () {
    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.

/app/templates/application.hbs

{{chartist-chart 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.

/app/templates/application.hbs

{{chartist-chart 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.

/app/templates/application.hbs

{{chartist-chart options=chartOptions data=model.chartData}}

/app/controllers/application.js

import Ember from 'ember';

export default Ember.ObjectController.extend({
  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 for different media queries. All of the same configuration options are available, but you provide them via the responsiveOptions attribute.

{{chartist-chart responsiveOptions=resOpts data=model.chartData}}

/app/controllers/application.js

import Ember from 'ember';

export default Ember.ObjectController.extend({
  chartResOptions: [
    ['screen and (min-width: 640px)', {
      showArea: true,
      lineSmooth: false,

      axisX: {
        showLabel: false
      }
    }]
  ]
});

Custom CSS

By default, the compiled chartist.css will be included in your app's vendor.css. If you want to use custom CSS you can tell the addon to not include the compiled version

In your app's Brocfile.js:

var app = new EmberApp({
  'ember-cli-chartist': {
    'useCustomCSS': true
  }
});

If you 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";

you can also import the Chartist settings scss:

@import "chartist-settings";

For more on custom styles see the Chartist docs
