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.
