Can you say precisely what you mean by `use the plot command in an
m-file' and exactly how you are invoking Octave and how you are
executing the m-file?

If it is a script and you are running

  octave script-file.m

then probably the reason that the plot disappears quickly is that
Octave and gnuplot are exiting as soon as the plot is drawn.  Two
possible solutions are to add

  sleep (N);

to the end of your script, in which N is the number of seconds to wait
before exiting, or add

  gnuplot_binary = "gnuplot -persist";

before any plotting commands.  The `-persist' option will cause the
X11 window to stay on the screen after gnuplot exits.
