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.

The cairo terminals do not support font attributes (bold, italics, etc...), yet.

To specify font in the output file you could use "-FFont:Size"

option, where font is any TTF available. E.g.
 

print('test1.png', '-dpngcairo', '-FDejaVuSansCondensed:14')
