'set size ratio -1' works only for 2d plot but not for 3D plot.
This seemingly trivial question is not so trivial - gnuplot
simply does not support isometric
3D plots! It is something for the gnuplot gurus to think on.

I could get x and y axis to be isometric
only by setting equal x and y ranges -
but then I had to play with z axis scaling, which was
not elegant and took lots of time.
Anyway, the x and y dimensions of the plots I want to make are not
equal, so cannot jump over it this way.

Any more suggestions anyone? I would really apreciate a solution.
