Matthias, can you tell us what version of gnuplot you're using? You can get 
that info by type "__gnuplot_version__" at Octave's prompt.

I don't have a windows machine to test this on, but this problem may have been 
fixed.

The prior discussion is at this link.

The changeset is linked to below.

Can someone confirm this change fixed the problem?
