When trying to plot a graph from octave, it fails to do so with all
kinds of gnuplot errors:

First of all, you should use octave3.0 instead of octave2.9, which is now
deprecated (we are waiting for Bug#457675 for having octave2.9 dropped from
Debian).
Second, I cannot run the script you indicated:
> script: http://www.wraith.sf.ca.us/ntp/allan.oct
Because it tries to open a file called "loopstats", which is not available.
So far, I cannot replicate the bug.

Have you by any chance set the environment variable GNUTERM? What does the
follow yield for you?
$ echo $GNUTERM
$ GNUTERM=x11 /usr/bin/octave3.0 -qf
octave:1> plot (randn (10, 1));
Tried it under X11 and then things work. So it seems X11 is required for
it to run. I thought and hoped it would emit a png/gif/jpg-file.
So the bug can be closed.
Thanks a lot,

To generate graphics files without displaying them on the screen, try
something like
figure (1, 'visible', 'off');
plot (randn (10, 1));
print -dpng foo.png

It's not too difficult to plot directly to a file, without a window
popping up, if that is what you need:

Ah ok! Thanks a lot!
