Does anyone know of any free software out there that will perform 3D
XYZ plotting based on data in Excel? I have seen previous posts asking
the same thing that were dated around 2002. I have Excel 2003, but I
still don't believe that capability exists. If there are free packages
that would do it, without spending a lot of $ on a package for just
this purpose, that would be great.

Thanks
