I saw that you were looking for use cases ... here is one of ours:
We are working on an application that nees a plotting and graphing
engine to display pretty pictures for our users in an eclipse view.
Most of our data is contained in a database and will be extracted, for
the most part, by pre-canned SQL queries, and we need to display the
data to the user in a bar, line, pie graph. To get started, we simply
need the rendering engine - nothing interactive, no printing, no user
customization, and we have no problem writing custom code to get the
graphs formatted (titles, tick marks, etc) properly. As the
application evolves, we will need more advanced features, but we
haven't collected the requirements yet.

Bryan,
Thanks for the information. A couple of follow-up questions:
First one is a confirmation -- sounds like the application is a desktop
Eclipse-based application rather than web based/J2EE. Correct?
How do you want to display the charts? Or, more specifically, what do you
want to render them to? Will a JPEG image work, or do you need SWT?
And this last is a curiousity one -- which desktop platform are you
targeting? Windows?
Regards,
Paul Clenahan

Swing & AWT are not desirable. We can't afford the extra memory
overhead. If we have to do the code, I will probably try draw 2d from
GEF.

Paul,
Our application is Eclipse running on the desktop. At some point, we
may want to provide a view to our data for managers that is web based.
Initially I don't think it will matter how the charts are rendered as
long as the rendering does not require Swing or AWT and the rendering
can be displayed in an Eclipse ViewPart. As our project progresses, we
may require additional functionality that may or may not change the
requirements on how the charts are rendered.
Our target platforms are AIX, Linux, and OS X.
Thanks for listening.
Bryan
