Ember-highcharts

A Highcharts, Highstock,
and Highmaps component for Ember CLI.

Requirements

* Ember CLI
* Ember >= 2.12.0

Installation

``
npm install @cubicl/ember-highcharts
`

Usage

This component takes in four arguments:

`handlebars
{{high-charts mode=mode chartOptions=chartOptions content=content theme=theme}}
`


$3

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 |

$3

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.

$3

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.

$3

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

$3

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

`js
// controller
import Ember from 'ember';
import defaultTheme from '../themes/default-theme';

export default Ember.Controller.extend({

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

});
`

`handlebars
{{high-charts chartOptions=chartOptions content=chartData theme=theme}}
`

Check out more chart examples in the tests/dummy app in this repo.

Configuration

This addon will load Highcharts by default. Highcharts has many optional features like Highstock and Highmaps.
You can add the emberHighCharts option to your ember-cli-build.js file to load these optional features:

`js
// all possible options
var app = new EmberApp({
emberHighCharts: {
includeHighCharts: false,
includeHighStock: true,
includeHighMaps: false,
includeHighChartsMore: true,
includeHighCharts3D: true,
includeModules: ['map', 'broken-axis', 'heatmap', ... ]
/* available modules:
accessibility, annotations, boost-canvas, boost, broken-axis, bullet,
canvas-tools, data, drag-panes, drilldown, export-data, exporting, funnel,
gantt, grid-axis, heatmap, histogram-bellcurve, item-series, map,
no-data-to-display, offline-exporting, oldie, overlapping-datalabels,
parallel-coordinates, parento, sankey, series-label, solid-gauge, static-scale,
stock, streamgraph, sunburst, tilemap, treemap, variable-pie, variwide, vector,
windbarb, wordcloud, xrange-series, xrange
*/
}
});
`

$3

Highcharts is already included in Highstock, so it is not necessary to load both.
Using the following configuration to load Highstock:

`js
var app = new EmberApp({
emberHighCharts: {
includeHighCharts: false,
includeHighStock: true
}
});
`

$3

Highcharts is not included in Highmaps. If you only need to use Highmaps use the following configuration:

`js
var app = new EmberApp({
emberHighCharts: {
includeHighCharts: false,
includeHighMaps: true
}
});
`

If you need to use Highmaps and Highcharts then use the following configuration:

`js
var app = new EmberApp({
emberHighCharts: {
includeHighCharts: true,
includeModules: ['map']
}
});
`

$3

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.

`js
// 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;
}
`

$3

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

`bash
ember generate chart
`

$3

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

`handlebars
{{#high-charts mode=mode chartOptions=chartOptions content=content theme=theme as |chart|}}
{{my-custom-legend chart=chart}}
{{/high-charts}}
`

_where my-custom-legend is an example component that may wish to access the chart instance_.

$3

This addon observes changes to chartData and redraws the chart using the highcharts
Series.setData method. You can extend this
component to handle advanced redrawing use cases like dynamically updating labels and titles
(ex: Chart.setTitle()).

`js
// components/dynamic-high-charts.js
import Ember from 'ember';
import EmberHighChartsComponent from 'ember-highcharts/components/high-charts';

export default EmberHighChartsComponent.extend({

contentDidChange: Ember.observer('content.@each.isLoaded', function() {
// add redraw logic here. ex:
var chart = this.get('chart');
var seriesName = this.get('content')[0].name;
chart.series[0].update({ name: seriesName, data: this.get('content')[0].data }, false);
chart.setTitle(null, { text: seriesName }, false);
chart.redraw();
})

});
`

`handlebars
{{dynamic-high-charts mode=chartMode content=chartData chartOptions=chartOptions theme=theme}}
