Thanks, Oscar, I have been looking at Scilab. I've got quite a bit of
university work to catch up before I reembark on my graph-making
mission, but this thread has provided me with valuable information. If
I need a hand with Scilab, I'll get back to you. I very much
appreciate the warm offer of assistance.
