Hi Pantxo,

The "gnuplot' solution works. Thanks a lot.

Best Regards,

Hi,

This is a known, graphics diver dependent, bug on Windows with the fltk
toolkit: 

https://savannah.gnu.org/bugs/index.php?47337

The octave-cli.exe program only has fltk and gnuplot toolkits so if you really 
need to use the command line you have two options:
* use gnuplot: 
    close all; graphics_toolkit ("gnuplot");
* try to figure out if the main Octave executable can be launched with the 
"--no-gui" option. I don't know how to do this on Windows but on linux it would 
be "octave --no-gui". This wil launch another octave flavor, in command line 
but with Qt toolkit enabled.

Pantxo
