M2014b+ graphics, changing legend orientation ex post

1 view (last 30 days)
Under new Matlab graphics, changing the legend orientation does not work well if the legend was created with all 4 output arguments, i.e. [LEGH,OBJH,OUTH,OUTM] = legend(...). On the other hand, the behavior seems to be fine when the legend was created using only LEGH = legend(...). Specifically I have encountered the problem that the legend shape gets adjusted but the legend contents stay according to the original legend orientation which makes my figures look unacceptable.
%%Works properly
figure;
hold on;
p1=plot(1:10);
p2=plot(10:-1:1);
lghandle=legend([p1;p2],{'Line 1','Line 2'});
set(lghandle,'orientation','horizontal');
%%Does not work properly
figure;
hold on;
p1=plot(1:10);
p2=plot(10:-1:1);
[lghandle,l2,l3,l4]=legend([p1;p2],{'Line 1','Line 2'});
set(lghandle,'orientation','horizontal');
Is this a bug?

Well, that help for that particular overload does state:
"Note: This syntax is not recommended. It creates a legend that does not support all graphics features. Instead, use the lgd = legend(__) syntax to return the legend object and set Legend Properties."
so I guess that would explain any odd behaviour.

I haven't really used legend, but I assume now that it is a graphics object in its own right that the one returned argument, 'lgd' is a legend object which you can interrogate to get various properties out of so I assume these would be included in there.

...the 'itemText' property which used to work in earlier versions is now empty and the usual sniffing point, the 'children' property, does not contain any information either. I am working with a simple line plot()
