Re: [jCharts-users] Gradient on each bar rather than across entire graph

[Travis R. <tr...@gm...>]

I don't think this will work very well for me since the paints are set
dynamically while creating the graph, so how would I get at which
paint is for which bar from the preRender method?  I would need a
axisValueRenderEvent.getPaint() or something.

Why doesn't jcharts just set the paint for each bar it draws?  Or
another way of putting that is why does it have the current behaviour?
