Klári,

Do I understand that you do get successful plots with other .m files? What
happens when you enter at the octave:> prompt

  octave:1> x=rand(1,10);
  octave:2> plot(x);

Do you get a plot?

Sometimes a plot command will work based on defaults, or leftover commands
from the previous plot, but the ordering with the plot command last in the
sequence is normal with a few exceptions (legend, for example).

This is complicated by the fact that I'm not on a Windows machine, so I
can't try things. Anyone got any ideas?
