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 isorganized 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:
http://gnuplot.sourceforge.net/demo_4.1/contours.htmlI have some gnuplot files for plotting 3D functions around, let me know if you'd like to take a look.
