[Octave-bug-tracker] [bug #31745] flipping images with hold on

[Søren Hauberg]

Follow-up Comment #6, bug #31745 (project octave):

I don't do as much image processing as I used to. When doing image processing
the basic visualisation work-flow is essentially:

  imshow (im);
  hold on
  plot (col, row, '*');
  hold off

where (row, col) denotes the coordinates of some points of interest in the
image.

Now with respect to the bug in question I am a bit unsure how things should
work. I tried generating a few plots in matlab hoping that this might shed
some light on the situation. I'm attaching a script and the resulting figure.
