Dear Robert, list

set(gca, "outerposition", [0 -0.1 1 1.2])

finally helped.
It really seems that the window size and ratio of gnuplot does not 
correct for the monitor resolution. Would be great is someone had a look 
at this.
But nevermind: I am currently writing my thesis using octave a lot and i 
want to thank all the developers and the whole comunity for their great 
work! Octave is such a great environment!

cheers,
Peter
