I use the Dave Hale's program ximage which is part of the CWP SU package available from cwp.mines.edu for this. It takes a 2D matrix of Z values and plots it with a variety of color scale options.
If you go to the Internet archive and search for seismicunix.com you'll find a wiki with many examples of using it.

Hello all,
I'm new to gnuplot and I'm trying to make a heat
map to achieve a interpolated 2D color gradient. I want to
be able to plot points with the structure x,y,z and I want
the z field to be the color variance. I'm trying to plot
3D objects where the color matches de Z field.

Can you guide me how to start?
