Follow-up Comment #4, bug #47455 (project octave):
I pushed a new version of legend.m, which will only affect OpenGL toolkits. I
attached a function which I used to try to devise a performance test of the
old versus new legend code.
For single axes, the timings are generally better with the new code:
* Adding legend item one after the other is now clearly faster (using
";displayname;" plot syntax)
* Changing legend properties after creation is also faster
Now with subplots, which was already very slow with the old code, performance
is poorer with the new code by 20%. For this we might need to implement an
external layout manager.
