Just looking at the code, I see no reason why your charting subclass wouldn't have been rendered in the Graphics2D context that I use for our charts. I'm not following. Simple pie charts, bar charts, etc, yes, the built-in charting can do all that. I needed to do some other stuff that the built-in Seam charting couldn't do. Do you mean why I wrote my own ChartComponent class? I initially tried to show my charts like: new ChartPanel(chart), using the JFree ChartPanel class. For whatever reason, that rendered as a bitmap. They probably have some buffering or whatever in there. So I just wrote a tiny java.awt.Component class. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4114899#...
