Follow-up Comment #3, bug #42881 (project octave):

Ok, I think I understand what you are seeing. If you type 'q' in the Octave
command window does the plot respond as you expect?

If so, then here is what is happening:

Octave uses a screen pager by default to show the output of commands one
screen at a time. In your script, if the x vector is too large, it will
trigger the pager which is waiting for you to command it to scroll or to exit.
This prevents the plot from responding because your command has not returned
control to the Octave prompt yet.

If you want to disable the pager to let the data scroll to the command window
no matter how large it is, type "more off" or "page_screen_output (false)" at
the Octave prompt. This can be added to your octaverc startup file to make
this a permanent preference.
