I am a Mac user who is trying to run some hardware that insists on
being attached by DMA to a PC type machine.  I've got the programs to
read the data and save it into a file in a nice format and I would
like to graph and curve fit the data.  On the Mac, my package of
choice would be KaleidaGraph, but a call to the publisher reveals that
no such tool exists in the DOS world.

My current solution is to read the data over on the Mac via sneakerNet
and use KGraph, but I'd (*gulp*) prefer a pure DOS solution.

Can anyone suggest DOS software to read a numerical datafile, graph it
and curve fit it with a general non-linear fits?  It should display the
fit over the data and provide the parameters.  It has to be able to
deal with custom formats and to be able to discard the first N lines of
data and choose different delimeters.  A crude programming language
(like KGraph has) would be a BIG plus.  A Windows package is also OK.
I am willing to spend up to $500-600 on this, so please feel free to
suggest expensive solutions.

Thanks all in advance.
