Thanks for the reply,
Actually I have used google. Always.
But as I'm sure you are aware, as time goes on and the internet fills with more and more crap, google becomes more and more useless each day.
At any rate, google only points to the more frequently referenced links.
I'm already aware of utilities such as GNUplot, Scilab, and a few others.
I also have gone through
www.osalt.com to search for other open source alternatives to programs as well.
The reason I posted, was to see if anybody knew of a 'hidden treasure'. That so called 'diamond in the rough' that doesn't really jump out on normal searches.
Aside from that, GNUplot and Scilab doesn't really do it for me. Especially compared to the Sigmaplot package. Granted the Sigmaplot package is quite an extensive & expensive packaged deal, which obviously stands to reason why it would have 'more' so to speak.
GNUplot is a little powerful tool, but it is quite limited as well.
Perhaps I may have jumped the gun a bit in haste needing the program.
I have not yet tried the MayaVi, but most of the others I've already perused.
Thanks/Cheers,
