Re: gnuplot_x11 driver with octave.app/gnuplot.app on Mac

[Thomas Treichl]

Ok Henry, sorry I misunderstood some things - and I hope I understand it right 
now ;) Thanks for the detailed explanation.

I've attached the modified startup script for Gnuplot.app, please replace

  /Applications/GnuPlot.app/Contents/Resources/bin/gnuplot

with my attached file. Then take an unmodified Octave.app and download the 
current version of drawnow.m from the CVS site

http://velveeta.che.wisc.edu/cgi-bin/cvsweb.cgi/octave/scripts/plot/drawnow.m

and replace

/Applications/Octave.app/Contents/Resources/share/octave/2.9.13/m/plot/drawnow.m

Then this works for me:

  bash$ export GNUTERM=x11
  bash$ octave # I just have Octave.app
  octave-2.9.13:1> plot ([1:10]) # Starts up X11 and plots in XWindow

If you don't like the xterm window that opens automatically when X11 is started 
then edit /etc/X11/xinit/xinitrc. Please tell me if this works for you...
