Scatter plot - Image instead of a dot, is it possible?

Hi Folks,

Is it possible to display an image/icon instead of the standard dot (at X,Y ) that's used in scatter plot charts? For example, if the chart is for displaying water content in some thing, then I want to display a droplet instead of a round dot. Is it possible with JFreechart (except by adding XYImageAnnotation). Thanks a lot.

StandardXYItemRenderer has a method you can override to return an image that will be drawn for a data item. It was contributed by another developer a long time ago, and isn't used a lot, but it should still work. Alternatively, it wouldn't be hard to implement a custom renderer to do what you want.
