[Octave-bug-tracker] [bug #30033] Image shown upside down when used in conjunction with "hold on"

[Rik]

Follow-up Comment #3, bug #30033 (project octave):

The problem is in image.m which is called from imshow.m.  The troublesome
lines begin at 140

  if (strcmp (get (ca, "nextplot"), "replace"))
    set (ca, "ydir", "reverse");
  endif

For, normal images we set the x and y axes limits but then reverse the
direction of the axis for y.  This is odd.  It also fails when hold is set
because the value of "nextplot" is "add" rather than "replace"
