Changing the color and shape of one data item in Jfreechart.

[manjusha0110]

Hi,

Can someone please let me know if it is possible to change the color and shape of one data item in jfreechart?. My scearnio is i am selecting one of the data points and marking it as ignore, so that i don't consider it for my calculations. I want to visually also show that the particular point is marked as ignore hence need to change the color and shape....Please help me...its urgent.

Yes you can do this. You need to determine which renderer class is being used, and create subclass of it where you override the getItemShape() and getItemPaint() methods to return a specific shape and color for the data item that you wish to highlight (or de-emphasise, depending on your requirement).
