Hi Samu, thanks for a quick response.
I'm doing a pretty large plots of XY data sets -- sometimes the data is dates,
sometimes the numbers huge Doubles, other times very small Doubles. And I need
to be able to zoom in. This kind of arbitrary data just cries out for
JFreeCharts (or something like it that I can merge into Jambi).
I'm happy to give your idea of faking a QTDIR a go, but to be honest I have no
idea how to begin that on a Windows box. I'm using Netbeans 6.8, and I have the
qtjambiawtbridge source code. Can you give me a quick "How To" (or point me to
one?). Which compiler should I use?
-Doug
(By the way for what it's worth integrating Jambi with Netbeans was a breeze).

You can always fake a QTDIR system, if awtbridge relies on that flag. Given it
doesn’t need private stuff (non-public headers of Qt).
If you need to do arbitrary drawing, Qt provides graphics view system, and
Jambi supports it well. It might be interesting alternative too.

get the correct range data from SQLite again, and redraw the plot. Or I could
just use the jambi-awt bridge and all would be well.
