RE: Gnuplot zoom with mouse

[Will Lentz]

Hi,

With gnuplot4.0 I added "set mouse" to ~/.gnuplot and that almost works.
Now I can right-click and see the zoom box, but it doesn't actually zoom
in.  If I turn on gnuplot debugging ('6') I see:
  octave:1> plot(1:10)
  octave:2> communication commands will be echoed.
  starting zoom region.
  set xr[2.35775862069:4.73141163793]; set
yr[2.28673361522:5.07901691332]; set x2r[ 2.35776: 4.73141]; set y2r[
2.28673: 5.07902]
  zoom region finished.
But the screen doesn't refect the zoom.

As an alternative I tried using gnuplot 4.2.  Now I no longer need a
~/.gnuplot file to enable mouse functionality.  That's cool, but
unfortunately the zoom box doesn't show up at all.  The middle button
can still be used to place markers, though...

Thanks,
Will

P.S.  Just as a sanity check - the right click zoom works when I run
either version of gnuplot from the command line (outside of octave).

Read the NEWS file (you can also see it if you type "news" at the
octave prompt).

Put

  set mouse

in your ~/.gnuplot file.

This should not be necessary if you upgrade to gnuplot 4.2 (plus, you
then get better support for color line properties in Octave).
