Unfortunately I don't know Microcal Origin. Do you know Gnuplot? That is a very
flexible scientific plotting program. There exists an extension Gnufit with
which you can do curve fitting. Furthermore, free "matlab clones" like Octave
and Scitech can generate gnuplot scripts. In that way you can do almost anything
with numbers and plotting. A drawback for you might be that Gnuplot has the
advantages as well as the disadvantages of being CLI (and not GUI) oriented.
