Octave does not plot

Question

When I try to plot a graph on GNU Octave, and try to use plot, it gives me the following output

set terminal aqua enhanced title \"Figure 1\" size 560 420           


        

Answer 1

To install it without aquaterm:

brew cask install xquartz
brew install gnuplot --with-x
brew install octave

vim ~/.octaverc
setenv("GNUTERM", "X11")
graphics_toolkit("gnuplot");
