Octave does not plot

And if you need Aqua terminal instead of X11 - this might help:

brew uninstall --force gnuplot

brew install gnuplot --with-aquaterm --with-qt4

You don't need to add setenv("GNUTERM","X11") or add GNUTERM env.var to octaverc file.

setenv("GNUTERM","qt") in your octave command prompt, it should solve the problem.

The following worked out for me

1. Uninstall any existing gnuplot on your OSX

   brew uninstall gnuplot

2. Install gnuplot with either X or X11

   brew install gnuplot --with-x

3. Finally, set the GNUTERM to X11

   setenv("GNUTERM","X11")

I think your problem comes from using the CLI.

As of January 2, 2014. If you're using OS/X 10.9 (Maverics) then you can opt to use integrated GUI from the binary package by downloading the Octave 3.8.0 .dmg. Use Octave-gui not Octave-cli, or otherwise start the GUI from the CLI.

A note about the gui from The Octave Home Page

But because it is not quite as polished as we would like, we have decided to wait until the 4.0.x release series before making the GUI the default interface (until then, you can use the --force-gui option to start the GUI).
