We use JFreeChart, for both J2EE and Tapestry applications, and I must
say its really simple to use. getting it to work in Tapestry took me a
few days though because I didn't know the framework very well, in the
end it needed a ridiculous amount of code (4 lines or so). I used the
outputstream writer. This snippet is from my IEngineService service()
method:
JFreeChart freeChart = chart;
WebResponse response = cycle.getInfrastructure().getResponse();
OutputStream out = response.getOutputStream(new
ContentType("image/jpeg"));
ChartUtilities.writeChartAsPNG(out, freeChart, width, 300);

I have used JFreeChart in some projects and it is very good. It
supports many chart types (including some you probably never heard of
before :), it's open source, it's relatively simple to use, and it's
very powerful. If there isn't any JFreeChart-Tapestry integration
written yet, it's about time! :) Unfortunately, i don't have the spare
time needed now. :(
There's Cewolf, a JFreeChart taglib I already used. Maybe we could
take some ideas from it.
