You should be able to do a new figure after each call to figure(n). If you
reuse the same n, the old figure will be overwritten, while if you change n,
you should be able to have multiple frames open simultaneously.

One other thing. Unlike MATLAB, the octave plot command follows after most
of the setup commands such as axis, title, etc. The exceptions are print and
legend from octave-forge. Modifying a MATLAB file usually involves moving
plot to later in the command sequence.
