Surface plot from data files

Rate this Message:
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 test.pdf |

Yup, I found those help commands later on last night, but I still get plots that look much "uglier" than the ones from the surf(). Maybe it would be better I found out what commands octave calls in Gnuplot when the surf() function is called, but when i open surf.m / surface.m I can't find any useful information.
Basically I would like to know how to get the same plot as in th the example PDF, but from scratch in Gnuplot, such that I easily can change whatever I want to change. Regards, drgz

you may set
gnuplot_binary ("tee logfilename | gnuplot") at the octave prompt to see which commands are sent to gnuplot.
