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.

Answer 2

Ok, I found the solution to this problem. Just run:

setenv("GNUTERM","X11")

Before you plot anything, e.g.,

plot(x,y)

Answer 3

I added:

setenv("GNUTERM", "qt")

to the octaverc file located in /usr/local/octave/3.8.0/share/octave/3.8.0/m/startup, and then it worked again.

Answer 4

Also you could add this line to your ~/.octaverc file:

setenv GNUTERM x11

- it works for me on mac os mountain lion.

Answer 5

Just add:

setenv ("GNUTERM", "X11")

to your octaverc file, normally located at /usr/local/share/octave/site/m/startup

Answer 6

COMPLETE SOLUTION:

1- Install x11:

brew cask install xquartz

Or, install from here.

2- Reinstall gnuplot:

brew uninstall gnuplot && brew install gnuplot --with-x11

3- Put these lines in ~/.octaverc

setenv("GNUTERM", "x11")
gnuplot_binary("/usr/local/bin/gnuplot")

4- Restart your mac
