Ember-cli-dimple

This addon provides an entrypoint for using PMSI-AlignAlytics/dimple with your ember-cli project.

Installation

Installation follows the blueprint pattern used in similar addons:

npm install ember-cli-dimple --save
ember g ember-cli-dimple

This will add the necessary entries in your bower.json and make available a new component in your project: {{dimple-chart}}

Usage

This addon must be extended by subclasses. This can be done by creating your own component:

ember g component custom-chart

and in components/custom-chart:

`import DimpleChartComponent from 'ember-cli-dimple/components/dimple-chart/component'`

CustomChartComponent = DimpleChartComponent.extend(...)

`export default CustomChartComponent`

The DimpleChartComponent provides two main hooks for customization:

remap: (data) ->

and

customizeChart: (chart) ->

The former will allow you to transform incoming data into the target format for your chart. Here is a remap example that aggregates data by series and returns an array of summed values:

###*
 * Transform time series data into a sum by series.
 *
 * @method remap
 * @param  {Array} data The time-series data as
 *                      [{ series: "x", value: y }, ..., { series: "x", value: yn }]
 * @return {Array}      The transformed data as [{ series: "x", value: sum(y1..yn) }]
###
remap: (data) ->
  _data = _.groupBy(data, "series")

  _data = _.map _data, (value, key) ->
    series: key
    value: _.reduce value, ((sum, num) -> sum + num["count"]), 0

  _data

The latter will allow you to set the axes and other properties on your chart prior to drawing:

###*
 * Customize chart before drawing
 *
 * @method customizeChart
 * @param {Dimple} chart The chart object
###
customizeChart: (chart) ->
  chart.addMeasureAxis("p", "value");
  pie = chart.addSeries("series", dimple.plot.pie);
  pie.innerRadius = "50%";
  chart.addLegend(0, 0, 90, 300, "left");

From there, you can add the custom component into your templates with a data binding:

{{custom-chart data=myDataSource}}

Notes on styling

The component attempts to redraw on window resize using a modified version of realityendshere/emberella:resize_handler. The sizing depends on CSS so please ensure your .dimple-chart has a well-defined width and height.
