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

The following worked out for me

1. Uninstall any existing gnuplot on your OSX

   brew uninstall gnuplot

2. Install gnuplot with either X or X11

   brew install gnuplot --with-x

3. Finally, set the GNUTERM to X11

   setenv("GNUTERM","X11")
