Java Charting libraries

[IHateMyJob2004]

I am currently tinkering with JFreeChart which seems to be a very good charting proejct.

I was wondering if there are any other projects out there that I should consider that are polished and easy to use. JFreechart has a few headaches with it so I thought I might want ot give one or two alternatives a go.

Thanks.




FYI: Others proejcts:
the JCCKit project (LGPL);
the QN Plot project (BSD);
the OpenChart2 project (LGPL);
the PtPlot project (UC Berkeley copyright);
the JRobin project (LGPL);
the Java Chart Construction Kit (LGPL, works with JDK 1.1.8);
the JOpenChart project (LGPL);
the jCharts project (BSD-style);
the JChart2D project (LGPL);
the Chart2D project (LGPL);
the ThunderGraph project (LGPL);
the E-Gantt project (Q Public License);
the MagPlot project (GPL);

I stumbled across JMathPlot a while ago because I was looking for something that would do 3d scatter or bar plots.
