Anyone know of a simple to use graphing program?

Well ... you ask for "inexpensive" in the "Subject: " header
and "simple to use" in the body.

Pick one!

A very good, and very powerful graphing program is called
"Gnuplot", and it is even compiled for Windows, as well as for my
favorite unix.

It is *free* for the download.

But it will take some work to learn to use. It can either plot
from tables of data, or can plot very complex functions from formulas,
but it will take some learning.

Here is the main URL:

http://www.gnuplot.info/

And here is a download for Windows:

You can either do your calculations in GNUplot, or do them in
the spreadsheet, and generate the tables to plot from.

Enjoy,
DoN.
