jpype with JFreeChart, anyone interested to help?

[oyster]

As you may know, there is no beautiful and free chart(not plot, you
can find the examples at http://www.jfree.org/jfreechart,
http://www.rmchart.com) module for python than runs on
windows/linux/mac osx.

On the other hand, there is a living
package(http://www.jfree.org/jfreechart) for java, and it is nice. So
what about make the interface to JFreeChart via
jpype(http://jpype.sourceforge.net), or rewrite JFreeChart in and for
Python to kick off JVM?

I have tried this, but since I don't know Java, I did not go further.
If anyone can help me with the following code, or organzie a
py_jfreechart team, or put up a pyFreeChart team, that would be great.

Thanks
