Public bug reported:
After updating to 16.04 some of my octave scripts broke because they use
gnuplot to print and the default has become gnuplot5 which has compatibility
problems with octave. This is a known problem upstream, see:
http://savannah.gnu.org/bugs/?42838
I found a workaround (if gnuplot4 is installed):
sudo update-alternatives --set gnuplot /usr/bin/gnuplot4-x11
This sets the gnuplot symbolic link to point to gnuplot4 instead of
gnuplot5 system wide which isn't ideal in the scenario someone needs to
use gnuplot5 elsewhere. I checked for a way to configure the gnuplot
path for octave but didn't see anything immediately obvious. Maybe I
missed something.
I suppose changing the PATH variable for octave might be a workable
patch. I figure this but probably won't get fixed before the release,
but I wanted to post it so anyone who runs into the problem will see the
work around.
