For what it's worth, matplotlib http://matplotlib.sourceforge.net/
produces beautiful contour plots. It is python based and easy to use.

I have some X,Y,Z data that I want to turn into a gray or colour
mapped contour plot.
The data aren't necessarily gridded, so I need interpolation.
I'm a newbie to Octave/Matlab, and could use a hint.
I've played with contourf(), which I can make work for functions, but
I need to load external data that is
organized as columns of X,Y,Z in ascii.
For cases like this, I prefer to plot straight in gnuplot instead of
going through octave. There are some examples here:

I have some gnuplot files for plotting 3D functions around, let me
know if you'd like to take a look.
