Update of bug #39925 (project octave):
Status: Confirmed => Ready For Test
_______________________________________________________
Follow-up Comment #27:
The problem with tackling it in the m-file is that someone can go ahead and
change the xdata or ydata range using the set() command. I think the check
needs to be downstream in gl-render.cc. Most of the code in graphics.cc is
general and applies to either the fltk or gnuplot backend. Thus, it shouldn't
care that values are floats or not. I checked in a changeset here
(http://hg.savannah.gnu.org/hgweb/octave/rev/36d646ead233) which seems to
solve the problem. When I used gdb to step through the code I realized that
we were exceeding the precision range which meant that diff (x) was coming out
0 and then divisions by 0 were causing all sorts of problems. Can you verify
that things work with the new changeset. If so, I think we can finally close
this bug.
