I was about to do that when I saw Stan's response:

I looked for other graphics calculators for Linux and found "GMT"
(Genius Mathematics Tool) and "Qalculate!". "Apper" does find them, so
I installed them (as "Genius Math Tool", "Qalculate!, and "Qalculate!
(GTK)"). I gave them quick, preliminary tries, and they seem to work.
Plots of sines and cosines do look nice and wavy. If those are not
adequate, I could wrestle with "GDL", or perhaps C++ writing files and
"gnuplot" reading them.
I'm closing this.
Bill.
