We are developing a RapidMiner plugin with own visualization (graphs). The category axis of some graphs have labels that should be clickable.
RapidMiner 5.3 uses Jfreechart 1.0.13 which has a bug: The category axis hides category labels in mouse events, thus Category label information is missing in event propagation: http://www.jfree.org/phpBB2/viewtopic.php?f=3&;t=29065/
This particular bug has been fixed in JFreeChart 1.0.14 (with another 90+ bugs):

* source/org/jfree/chart/axis/CategoryAxis.java (draw): Add axis entity before drawing labels.
We have tested JFreeChart 1.0.14 (also with JCommon 1.0.17) and RapidMiner 5.3 together and everything works fine in our own tests (which is certainly not a full RapidMiner test suite).
The question is: Is there any chance to test RapidMiner with JFreeChart 1.0.14 and include it in the next release?
thanks for pointing that out. I've created an internal ticket for that. I'm not 100% sure that we will update the library with the next release but it is on our agenda now. I think the chances are quite good that it will make it into the next release.
