Octave graphics and Octave in teaching laboratories

Sorry to jump in with some possibly uniformed questions about Octave.

We (in Physics) and our Math colleagues are seriously considering using
Octave next year in (at least lower-level) teaching labs, in order to
not have to expand our Matlab license.

I wondered if anyone out there had any thoughts to share on this

The sorts of calculations I'm demonstrating don't make much use of
built-in Matlab functions, and of course the basic language constructs
are the same, so I have little difficulty with most parts of my

The big difference is the plotting. For the most part I don't see it as
too much of a problem --- both Matlab and Octave tend to require some
slightly confusing incantations to get the pictures :-)

However, in the release that I currently have availiable to me (0.79
--- we are installing 1.0 RSN...) there appears to be no way of
displaying two pictures at the same time. e.g. a function + fourier
transform. Is there this capability in 1.0, or upcoming versions?  In
Matlab I have been doing this with subplot. I know that sort of thing
is not supported by Gnuplot, but I'd be happy enough if I could just
have several graphics windows instead, presumably with multiple copies
of Gnuplot (?!).
