The problem is that the default configuration of Homebrew's gnuplot doesn't 
support any terminals for displaying the plots.  To add support for x11, ...

        brew uninstall gnuplot;
        brew install gnuplot --with-x

I don't know if Homebrew supports qt or not.  You might experiment with that 
... or ask the Homebrew help list.

Homebrew definitely doens't provide Aquaterm.  But if you are up to a bit of 
hacking, you'll first need to download and install Aquaterm

        http://sourceforge.net/projects/aquaterm/

And then setup the Homebrew build of gnuplot to link to the Aquaterm libs.  If 
you need help with that, please inquire on the Homebew and/or gnuplot help 
lists.

Beware of multiple installs of Aquaterm and/or gnuplot.  You'll save yourself a 
lot of head-aches if you only have one of each installed on your computer.
