[Pw_forum] plotband.x and displaying style

[Masoud Nahali]

   Dear  Gabriele Sclauzero


  Many thanks for your kind attentions and helps. Yes ! I have plotted the
band structure with GNUPlot and I have not any problem except
 where I must draw vertical lines that are related to the specific points in
the Brillouin zone :

K: 0.33333 0.33333 0.0
Gamma:0.0 0.0 0.0
M: 0.5 0.0 0.0
K: 0.33333 0.33333 0.0
H: 0.33333 0.33333 0.5
A: 0.0 0.0 0.5
L: 0.5 0.0 0.5
H: 0.33333 0.33333 0.5

  I do not know in which way plotband.x attributes a value in the "X" axis
to the above points. As one may saw, plotband.x creates vertical lines at
that points. It seems that there is not any information about the attributed
points on the X axis in the *.xmgr file. I need a help to draw that vertical
lines.

Best Wishes
