Chart events not exposed - Feature request

[temecom]

As a C3 user/developer it would be nice to have the chart actions linked to the ember action chain. This would provide interaction with other components on the view eg:

A group selection on the chart could trigger a refresh of a table showing the data details.

This would involve catching the 'once' method callback in D3 and emitting it as an Ember action.

Absolutely agree. This is planned. For whatever reason I neglected to create an Issue. Thank you!

I would love to receive a Pull Request adding this functionality 😄.

I will give it a shot.

I looked for the D3 instance but could not find it. Where is it buried?

I think the applicable code would be https://github.com/Glavin001/ember-c3/blob/master/addon/components/c3-chart.js#L118-L120

How about this for expected usage:

{{c3-chart data=model chart-created=(action "chartCreated")}

And your Controller or Route would have an action named chartCreated that could save the chart instance passed to itself to be used later.

{
    actions: {
        chartCreated: function(chart) {
            this.set('myChartProperty', chart);
        }
    }
}

This would also work without any internal changes to Ember-C3:

{{c3-chart data=model chart-created=(mut chart)}

Where (mut chart) would generate a function that access the chart instance and would set the property chart on the controller.

See issue #77

chart actions/events were available on the component but have been updated with pr #79. Dummy app has examples using closure actions on chart events. Update will be published when issue #77 checklist is completed
