How do I plot to file only on octave-3 (ie. no X11)

[emil Karlson]

Good evening

I was  wondering is it possible to plot to file only on octave-3, or
plot to NULL and then print as usual.

On octave-2 this was easy with gset terminal ps and such.

This is relevant because:
1) I may want multiple plots for animations.
2) I may want to work over ssh and X is very slow in these situations.

Best regards
