[Octave-bug-tracker] [bug #42034] legend () call should not create legend in some cases

[Rik]

Follow-up Comment #2, bug #42034 (project octave):

I agree with Mike that it is unclear what legend() is supposed to do in this
case.  If you read the documentation for legend it says that when no label is
supplied it should create a label using the sequence "data1", "data2", ...

Can someone try the following example in Matlab


plot (rand (3,3))
hl = legend ()


Octave seems to do the correct thing here in that it builds a legend object
with 3 labels (data1, data2, data3), and then returns the handle.  However,
maybe you are supposed to do


plot (rand (3,3))
hl = legend ('show')


if you want to use default labels on a plot that doesn't have a legend.
