highlight selected bar item?

[jiangshachina]

Hi,
When I used an old version JFreechart, I could highlight a selected bar chart item with method CategoryPlot.setSelectCategoryIndex(),
now, I'm using JFreeChart 1.0.13, how to achieve the same goal?

Thanks in advance!

I think I made a gread mistake, JFreechart may never provide such feature.
Now, I customize the BarRenderer, and override the drawItem method.

Thanks!
