[Gnuplot-info] Surface plot from data files

[drgz <sy...@ho...>]

Hello,

I'm trying to make a surface plot using data I've exported from Octave. I
found it to be easier to edit the labels etc with Gnuplot when I did my 2D
plots, so I want to do the same with the 3D plots, but I simply don't get
how to organize the data such that the plot becomes the same as when using
surf() in Octave.

Example;

I got two vectors and a matrix I want to plot:

size(freqvec) = 101 x 1
size(pinvec) = 26 x 1
size(s22vec) = 101 x 26

Should I save these to three separate data files, or should I save them all
to the same file? And how is the syntax for linking them together in
Gnuplot?

I've tried both saving them to different files, and to the same file, but I
simply don't manage to get it right.

When using Octave, I get the plot as in the attached file, which is nice,
but as I want to tweak a little on the figure I thought it might be easier
doing it from Gnuplot directly.

So can anyone point me in the right direction, or know somewhere I can read
about how to get the plot right?

Best regards,

drgz
