Are you able to run gnuplot from a terminal window? i.e ...

(1) Open a terminal window
(2) Type "gnuplot"

Does gnuplot run?

If not, and are using a gnuplot app bundle (which you downloaded from 
somewhere) then be sure it is in your Applications folder, open a terminal 
window and type ...

        sudo ln -s /Applications/GnuPlot.app/Contents/Resources/bin/gnuplot 
/usr/local/bin/gnuplot

This will create a symbolic link to the gnuplot executable. This link will be 
in a location where Octave will find it.  When you type this command, you'll be 
asked to validate this command with your password.

After that your Octave should work.

If you don't mind some advice, I recommend you install Octave and gnuplot using 
a package management system.

There are a few package management systems available for MacOS. The most 
popular ones are Fink and Macports. Some of the individuals how frequent this 
use one or both of these.
