[comp.sys.mac.apps] Looking for a good equation grapher, I think.

I'm a free-lance technical writer and I'm currently writing instruction
and service manuals for a designer and manufacturer of television test 
equipment.  The problem is that I'm trying to capture test signal wave-
forms so I can display them (with pertinent information) in these manuals.

So far, I've had less than spectacular results using Pizazz Plus on a PC
as a screen-capture utility.  What I've been doing is to take the resulting
compressed TIFF files and ship them to my Macintosh, where I convert them
to uncompressed TIFF (the only kind of TIFF that SuperPaint 2.0 can handle).

In SuperPaint, I add the voltages, times, and other data required by the
client.  The waveforms look horrible when I finally get them opened up in 
SuperPaint.  Many of the traces are just plain missing.

But these waveforms can all be represented by mathematical equations.
Each trace may represent several equations, but the point is, that I could
construct the trace I need from the pieces.  So I'm wondering if any of
you have an opinion on which equation grapher might let me enter an
equation and then display the results graphically.

Any opinions, suggestions, or comments would be welcome, believe me.
Actually, if I could just figure out how to get the quality I need from
Pizazz Plus (or some other screen capture utility) and some combination 
of Mac software, my life would probably take a turn for the better...
