(Re-arranged for bottom-post reply)

Actually, gnuplot has never worked this way with Octave since it first
introduced the mouse functionality (at least not in X-windows).  It is
not automatically enabled if gnuplot's input comes from a pipe, which is
is the case in Octave.  To get mouse functionality, I have the following
lines in my .octaverc:

  gnuplot_command_plot = "set mouse; plot";
  gnuplot_command_splot = "set mouse; splot";

Occasionally something happens internally and I lose mouse-ability
altogether, and can't get it back without restarting Octave.  I don't
know if this is a problem with Octave or Gnuplot, but it usually comes
about after much zooming, un-zooming, gsetting, etc. (it is not easily
repeatable, so I've never bothered to track it down).  If someone has a
better solution than the .octaverc lines above, please share.
