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

[Henry F. Mollet]

Hi Thomas,
You've seen my reply using gnuplot directly but that's not the goal.

I've also tried your other suggestions in reverse order:

Yes, this work, but then I can no longer use AquaTerm. Ideally I'd like to
toggle between x11 and AquaTerm as needed. I've tried
__gnuplot_set__ term aqua
but it no longer works in octave-2.9.13.
Works fine with octave-2.1.71/gnuplot-4.0

I had no luck with this:

octave-2.9.13:1> fplot('sin',[0,2*pi])
