If you know what you are doing, gnuplot may solve your problems. Few 
other programs allow as much control over your graphics output as gnuplot 
does, and few programs can output in so many format to work with 
different hardware and software. It also comes with a curve fitting 
routine (Marquard algorithm). Only for obstinate cases you may need an 
additional curve fitting program which uses the Simplex algorithm, as 
simplex gives usefull results even in some cases were Marquard breaks 
down.

Gnuplot is freeware, current version is 3.6 (officially still beta, but 
very stable).
