I used to be able to create a legend; use copyobj to make a permanent duplicate of it, then redefine the original legend. I see ( R2014b changes to legend ) that copyobj now has to copy the axes as well as the legend. This is a real nuisance as one then has all the axes children copied with them. The new, copied axes with copies of all my lines sits in front of the gca current axes; when I add points or change the legend, they are hidden behind the copied axes. This is just horrible, terribly inelegant. All I want is one axes with two legends on it (not two axes with the current axes inaccessible behind a copy): it worked fine before and now it is broken.
I have fudged some code that hides all the copies (attached) - is there a neater way of doing this? perhaps legend(h, {'strings'}, 'new') ?
