I would like to do a 3d surface using the 4th column as the color scale. It seems to be possible using the newest version (gnuplot 4.2.5) according to the pm3d demo. But unfortunatly the demo file is a binary file so that I don't succeed to get inspired form the given example.
Do anybody knows how to do?
the file is composed by 4 columns as follows : x y z energy
The 3d surface has to ba made by using 1:2:3 and the 4th collumn to color the surface.
Thanks at lot.
