Follow-up Comment #3, bug #68150 (group octave):

That's not what I mean. In MATLAB execution, executing set(xlh,'Visible','on')
can change it without executing set(gca, "visible", "on"), whereas Octave
behaves differently.

MATLAB:

>> pie(1:5)
>> xlh = xlabel('Is this Visible?');    %also invisible

>> set(xlh,'Visible','on')      %MATLAB can display it now
>> get(xlh,'Visible')

ans = 

  OnOffSwitchState enumeration

    on

The pie3 function has the same issue. As for why pie and pie3 in MATLAB
initially hide labels while other plotting functions like stem and bar do not,
that is another question.
