黑色背景的拉力赛图表

Question

I see a couple questions out there like this: Rally Standard Report charts with a black background , where people want to be able to change the background color of the charts. Has anyone figured out how to set the theme for the highcharts rendering? Ideally, I'd like to do a chart like this: http://www.highcharts.com/demo/area-inverted/gray .

I'm using java script with the 2.0rc1 interface.

I found this while trying to solve a similar problem: Rally chart documentation

If you use the updateBeforeRender option, you can reference Highcharts, specifically the method:

Highcharts.setOptions();

which is what you need to use something like the gray theme.

Here is what my chart config looks like:

App.down('#chartContain').add({
    xtype: 'rallychart',
    updateBeforeRender: function() {
        Highcharts.theme = {...}
        Highcharts.setOptions(Highcharts.theme);
    }
    ...
}

Copy the theme code from the Highcharts documentation and you should be good to go!
