Thank you for your help, it worked.

But now there's another problem with plot annotations. Let's say I want
an x axis label with an italic font:
> xlabel('text here','fontname','Arial_Italic','fontsize',14)

if I print the figure with "-dpng" it shows the correct font, but with
"-dpngcairo" it doesn't. Also, whatever fontname I set, it prints the
figure using the same default font.

I also tryed with something different, like [see Octave manual, 15.2.7
"Use of the Interpreter Property"]:
> xlabel('{\it text here}','interpreter','tex')

but I receive a warning telling me that the syntax isn't correct.
