[Octave-bug-tracker] [bug #61532] "Automatic limits for current axis" button doesn't respect "axis tight"

[Markus Mützel]

Follow-up Comment #23, bug #61532 (project octave):

Running the first part of the test for `camlookat` in Matlab R2021a, I see the
following:

>> [x, y, z] = peaks ();
   s3 = surf (x, y, z/5);
   hold on
   [x, y, z] = sphere ();
   s2 = surf (x/2, y/2+1.5, z/2+2);
   s1 = mesh (x/2-4, 3*y, z/2 - 1);
   axis equal
   axis tight
>> get(gca, 'XLim')
ans =
   -4.5000    3.0000
>> get(gca, 'YLim')
ans =
    -3     3
>> get(gca, 'ZLim')
ans =
   -1.5000    2.5000


In Octave hg id 4b367bf5eb16, I see:

>> [x, y, z] = peaks ();
   s3 = surf (x, y, z/5);
   hold on
   [x, y, z] = sphere ();
   s2 = surf (x/2, y/2+1.5, z/2+2);
   s1 = mesh (x/2-4, 3*y, z/2 - 1);
   axis equal
   axis tight
>> get(gca, 'XLim')
ans =
  -4.5000   3.0000
>> get(gca, 'YLim')
ans =
  -3.7500   3.7500
>> get(gca, 'ZLim')
ans =
  -3.2500   4.2500


The axes limits (in y- and z-direction) after `axis tight` seem to be much
tighter in Matlab than in Octave.
