I\'m using Windows 7 64 bit. Each time, I\'m using plot function, plot windows will shows and draws successfully, but after that it stops responding and must shut down it.>
The following is solution for plot window freezing when running Octave from within Emacs, credited to John Lawrence Aspden and user2699 from the question How to get Octave's plot to work under emacs?. It's brought here because this question is much easier to find.
The problem might be caused by Emacs octave-mode's --no-line-editing switch, you can fix it by M-x customize-variable RET inferior-octave-startup-args RET and change --no-line-editing to --line-editing.
