Re:[Gnuplot-info] Color points with pm3d?

[Gavin B. <gav...@ya...>]

Aaarrrgghh Joe, thats a tough one! As I understand it
(although I've only played with the pm3d options) the
pm3d option seems to create an extra surface and the
original surface is the usual one. The old surface had
a set of colours that you could use - which can be
chacked out for your terminal by typing test.

The only way I ever changed the colours was by hacking
into a postscript file after I had generated the plot
and changing the colours by hand which is not much use
if you want to change a whole bunch of them to match
the pm3d stuff.

Maybe you could just plot the difference between your
data points and the curve to give you an idea of how
good the fit is?
