Re: CustomRenderers

to override the default Paint used by the bar or point, simply set a different Paint to the
Graphics2D Object in the preRender method in your PreAxisValueRenderListener.  Take a look at the
source of org.jCharts.axisChart.customRenderers.axisValue.renderers.BackgroundRenderer

Yeah, the code you submitted is posted under the patches section of the sourceforge site.

Times are tough right now for me as I am trying to start my own business while I have a full time
gig so I have had no time to do anything for quite some time...
