Octave plotting error

Question

I am new to octave, I just tried my first plotting with Octave 3.4.0 when I get the following error. Any help will be much appreciated. The gnuplot version is 4.6

Answer 1

or put this line into your .profile (or .zshrc whatever):

export GNUTERM=x11

this will make all gunplot invokations (besides Octave) to output to x11.
