[Wien] Question about 2D-Fermi Surface plotting

[Gregory Pomrehn]

The file is a regular grid of data points in the plane you selected.  In
your case it is a 20x20 grid.  The following rows contain 400 data points
corresponding to each point in the 20x20 grid.  Specifically, assuming your
plane is in the X-Y plane, the first data points correspond to:

        X                    Y                         E
1*0.8246/20    1*0.8246/20     -0.25961699E+01
2*0.8246/20    1*0.8246/20     -0.26794386E+01
3*0.8246/20    1*0.8246/20     -0.27745819E+01
4*0.8246/20    1*0.8246/20     -0.28575199E+01
5*0.8246/20    1*0.8246/20     -0.28953395E+01
....

I might have the order of X and Y swapped, but that is the idea.  If you
want to use the splot function in gnuplot, you will probably need to
reformat the data.  See an example here:
http://gnuplot.sourceforge.net/docs_4.2/node331.html

Could be easier to install pgplot and plotgenc.
