Gnuplot is telling you that it wasn't built with support for Mac OSX's native "aqua".

First we should check which gnuplot Octave is finding.

What does ...

        [a, b] = system ("which gnuplot")

... return?

Here is the return for this query:

octave:3> [a,b] = system("which gnuplot")

a = 0

b = /usr/local/octave/3.8.0/bin/gnuplot

Ok. Octave is finding the version of gnuplot that is present in the bundle, but that version was not build to support native graphics.

If you want to continue using gnuplot, then you can try to use gnuplot's qt or x11 terminal.

close all

setenv GNUTERM qt

figure (1)

clf ()

plot (rand (3))

title ('Qt')

setenv GNUTERM x11

figure (2)

clf ()

plot (rand (3))

title ('X11')

Alternatively, you can use OpenGL for graphics.

close all

graphics_toolkit fltk

plot (rand (3))
