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

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 

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.
