Graphics, Figures & Tables ⇒ Surface plot with pgfplots

[mgulin]

Hi all!
I'm trying to plot a surface using pgfplots. Here is the MATLAB-generated surface plot, that is what I'm trying to get with pgfplots:

What I'm getting with pgfplots is this:

Please find attached the .tex code and the .txt file with data.

P.S. I also have GNU plots installed on my machine, but I didn't manage to get what I want here.

Any help is more than welcome. Thank you in advance!

I would use a surface plot instead of a patch plot. I can see a structure, still it looks different to the matlab plot - is the matlab plot really correct? How exactly did you make it in matlab?

Here is the MATLAB code. The single_diode_surface.txt in MATLAB_code.zip file is the same as the one posted in the first post.

I managed to get contour plot in LaTeX by using GNU plot:
