Installation

Usage

This component takes in five arguments:

<HighCharts
  @mode={{this.mode}}
  @chartOptions={{this.chartOptions}}
  @content={{this.content}}
  @theme={{this.theme}}
  @callback={{this.callBackFunc}}
/>

mode

The mode argument is optional and it determines whether to use Highcharts, Highstock, or Highmaps. The possible values are:

Value	Description
falsy value	defaults to Highcharts mode
"StockChart"	uses Highstock mode
"Map"	uses Highmaps mode
"Gantt"	uses Highcharts Gantt mode

chartOptions

The chartOptions argument is a generic object for setting different options with Highcharts/Highstock/Highmaps. Use this option to set things like the chart title and axis settings.

content

The content argument matches up with the series option in the Highcharts/Highstock/Highmaps API. Use this option to set the series data for your chart.

theme

The theme argument is optional and it allows you to pass in a Highcharts theme.

callback

The callback argument is optional and allows you to pass in a function that runs when the chart has finished loading (API).

Example Bar Chart

Here's an example of how to create a basic bar chart:

// component.js
import Component from '@glimmer/component';
import defaultTheme from '../themes/default-theme';

export default class BarBasic extends Component {
  chartOptions = {
    chart: {
      type: 'bar',
    },
    title: {
      text: 'Fruit Consumption',
    },
    xAxis: {
      categories: ['Apples', 'Bananas', 'Oranges'],
    },
    yAxis: {
      title: {
        text: 'Fruit eaten',
      },
    },
  };

  chartData = [
    {
      name: 'Jane',
      data: [1, 0, 4],
    },
    {
      name: 'John',
      data: [5, 7, 3],
    },
  ];

  theme = defaultTheme;
}

<HighCharts
  @chartOptions={{this.chartOptions}}
  @content={{this.chartData}}
  @theme={{this.theme}}
/>

Configuration

Highstock, Highmaps, etc

We now use dynamic imports to import the Highcharts packages you need based on the mode argument passed.

Global Highcharts Config Options

Ember-highcharts provides its own set of default configurations in addon/utils/option-loader.js. At runtime you can optionally configure custom styles by providing a app/highcharts-configs/application.js file. This file should provide a hook that returns the final configuration.

// app/highcharts-configs/application.js

export default function (defaultOptions) {
  defaultOptions.credits.href = 'http://www.my-great-chart.com';
  defaultOptions.credits.text = 'great charts made cheap';
  defaultOptions.credits.enabled = true;

  return defaultOptions;
}

Generating Chart Components

Ember-highcharts also provides blueprints to easily create sub-classes of the default high-charts component.

ember generate chart <chart-name>

Obtaining a Reference to the Chart Instance

The chart instance is exposed to the yielded content if used in block form:

<HighCharts
  @mode={{this.mode}}
  @chartOptions={{this.chartOptions}}
  @content={{this.content}}
  @theme={{this.theme}}
  as |chart|
>
  <MyCustomLegend @chart={{chart}}>
</HighCharts>

where <MyCustomLegend> is an example component that may wish to access the chart instance.
