| The alias command sets up a variable that applies only in your shell.
| It won't help octave find gnuplot.  You probably need to set up a symbolic
| link to gnuplot in some directory on your path.  Try:
| 
| ln -s /Applications/gnuplot/Gnuplot.app/Contents/Resources/bin/gnuplot \
| /usr/local/bin/gnuplot

Or, add the directory containing gnuplot to your PATH before starting
Octave.  In your .profile:

  PATH=$PATH:/Applications/gnuplot/Gnuplot.app/Contents/Resources/bin

Or, use

  gnuplot_binary ("/Applications/gnuplot/Gnuplot.app/Contents/Resources/bin/gnuplot");

in Octave.  But probably setting PATH is better because then you can
also start Octave from the shell.
