[Octave-bug-tracker] [bug #65442] legend.m fails on polar plot when executed more than one time

[Pantxo Diribarne]

Follow-up Comment #11, bug #65442 (group octave):

@Rik: I have a work in progress patch (see attached). It currently solves the
issues at hand but I have been trying to make the following example work as in
ML:


clf; hold on;

h1 = plot (1:10, "displayname", "visible");
h2 = plot (10*rand (1,10), "handlevisibility", "off", ...
           "displayname", "invisible");

legend () ## Only the first line has a legend

legend ([h1 h2]) ## Both lines now have a legend

disp ("Click any key to add a new visible item")
pause
h3 = plot (10*rand (1,10), "displayname", "visible");
## The second item should not disappear

I.e. objects with invisible handles don't get a legend by default  (that
works) but one should be able to add a legend to a purposely invisible object
(that works) ans the automatic update for further item addition should not
remove it (that still doesn't work).
