Hello! If this has been asked many times, I apologize....

I am wondering if any plotting packages are available. I am using
Lightspeed C and so looking for something callable from withing the
application written in C. The specific task I am into is mainly
to visualize signal waveforms and spectral features on the screen--of
course, it would also be nice if I could dump them to the printer.
Sometimes jobs involve 3D plotting, which is basically why I'm looking
for something off-the-shelf.
   In particular, I would like to hear about any {good|bad} stories about 
GrafPak for LSC4.0, which is the only candidate so far. But I would
appreciate pointers to other products as well.

Any {opinions|suggestions|pointers} via e-mail to:

	aki@speech1.cs.cmu.edu

would be welcomed, since the question sounds a little bit naive and awkward.

Thank you very much!
