[Octave-bug-tracker] [bug #60759] test subplot fails on hi-res display

[Markus Mützel]

Follow-up Comment #1, bug #60759 (project octave):

In the thread Dmitri linked in the OP, we found that the "position" property
is off by a few pixels.
Copied together from across different postings, on Dmitri's monitor:

>> hf = figure();
>> get(hf, 'position')
ans =

   300   207   560   413

>> get(groot, 'defaultfigureposition')
ans =

   300   200   560   420

>> for ii=1:9 hax(ii) = subplot(3,3,ii); endfor
>> get(hax(4), 'position')
ans =

   0.1300   0.4421   0.1576   0.1508

>> hax_new = subplot (2,1,1);
>> get(hax_new, 'position')
ans =

   0.1300   0.6248   0.7750   0.3002


On my monitor:

>> hf = figure;
>> get(hf, 'position')
ans =

   300   204   560   416

>> get(groot, 'defaultfigureposition')
ans =

   300   200   560   420

>> for ii = 1:9
  hax(ii) = subplot (3,3,ii);
endfor
>> get(hax(4), 'position')
ans =

   0.1300   0.4255   0.1818   0.1840

>> hax_new = subplot (2,1,1);
>> get(hax_new, 'position')
ans =

   0.1300   0.5999   0.7750   0.3251


The failing BIST might just be a consequence of the figures having different
sizes. In that case, subplot (probably correctly) uses different positions for
the axes in the grid.
It looks like with that slightly different layout, the middle row of the 3x3
grid does *not* overlap with the upper axes of the 2x1 grid on Dmitri's
monitor.
But they do on mine.

@Dmitri: Could you please test if this modified test works for you?

hf = figure ("visible", "off");
set (hf, "position", get (groot, "defaultfigureposition"));  # FIXME: This
step shouldn't be necessary
unwind_protect
  for ii = 1:9
    hax(ii) = subplot (3,3,ii);
  endfor
  subplot (3,3,1);
  assert (gca (), hax(1));
  subplot (2,1,1);
  assert (ishghandle (hax),[false(1,6), true(1,3)]);
unwind_protect_cleanup
  delete (hf);
end_unwind_protect
