[Pkg-octave-devel] Bug#391033: octave2.9: bad behaviour with hold on/off

[Francesco Potorti`]

Package: octave2.9
Version: 2.9.7-2
Severity: normal

In Octave 2.1, these two commands give the same result: they first show
a segment for one second, then they show two segments:

plot([1,2],[3,4]);sleep(1);clearplot;hold on;plot([0,1],[3,4]);plot([3,2],[3,4]);hold off
plot([1,2],[3,4]);sleep(1);hold on;clearplot;plot([0,1],[3,4]);plot([3,2],[3,4]);hold off

In Octave 2.9, they do different things, both wrong:

- the first command line shows one segment, then three segments
- the second command line shows one segment, then another single segment
  and, in quick succession, yet another single segment
