Dear listmembers,
der Panxto,
thank you for the hint - well, as I use the octave version 4.2.1 right now 
this is working for me as well!

However, due to other similar issues/problems with the graphical 
representation I could achieve I dumped a set of gnuplot commands into a file 
now and did directly what I wanted to do.

It is a user friendly approach to try to hide the actual graphical interface 
of a secondary tool from the user in order to allow him to learn one single 
language only. However there ought to be a means for dumping the commands 
controlling the secondary tool into i.e. a data- and a plotfile on request 

By the way: this has to exist anyway as this is mandatory in order to print 
for example with gnuplot. And whether one pipes something to an application or 
writes into a file ought to be not a big thing.

Such issues like the one discussed right now (and several more I've been 
stumbling across during the last years) could be solved on the direct way, 

Neither gnuplot nor octave are perfect when it comes to achieving printouts 
the way one needs them. However it becomes very difficult if the tweaks for 
tool "A" you are aware of are kind of hidden behind a meta language within 
tool "B" so you cannot access them the direct way.

My 2 cents only.

Thanks again,
best regards
