Support ability to use Plotly renderers

[Flaurite]

Environment

• Platform version: 7.2
• Client type: Web

Description of the bug or enhancement

See forum thread.

pivottable.js provides optional renderers such as Plotly, Google Charts and etc. See pivottable.js wiki. To improve c3 charts we can add option to use Plotly renderers. It is not complicated to add Plotly renderers:

private static native void addPlotlyRenderers(JavaScriptObject config) /*-{
    config.options.renderers = $wnd.$.extend(
	                        config.options.renderers,
                                $wnd.$.pivotUtilities.plotly_renderers);
}-*/;

The full example of using Plotly here: pvtdemo.zip. Open Pivot Screen.

So things we should do:

• Update pivottable.js version
• Add option to use Plotly renderers
• Improve ability to add new renderers to the enum Renderer
