Dear all.

My 3d mesh plotting is currently being colored using gnuplot pm3d. However the pm3d colours should be related to a variable different from the z value.

It is indicated that (in addition to x,y,z) a fourth column of data should be used for gnuplot to read RGB color information (http://www.gnuplotting.org/manpage-gnuplot-4-6/#Q1-1-536).

I only recently started using gnuplot and am further constrained by the fact that gnuplot site is temporarily offline (http://gnuplot.sourceforge.net/demo/).

Can anybody can let me know how to relate number values with colours?
