Matlab 2014b: Copying just the legend from existing figure into subplot

Hi there,

I'm looking for how to get the legend from an existing saved figure and load it as the legend in a figure of subplots.

In 2013 I used to be able to do:

h1 = hgload('file.fig');
leg_ax = findobj(h1,'type','axes','Tag','legend','-not','Tag','Colorbar');
s6 = subplot(2,3,3);
copyobj(leg_ax,get(s6,'Parent'));

Thanks, Ashley

One way is to save and reuse just the legend object itself, e.g.,

        plot(1:5,2:6,1:5,0:4); 
         hleg=legend('First Line', 'Second Line');

            save tst hleg
            clear hleg
            load tst hleg

        figure;      
        s6 = subplot(2,3,3);

        plot(10:10:50,(2:6).^2,10:10:50,(0:4).^2);
          legend(hleg.String{:})

The plot and legend were created and saved as a .fig file. How would I do this using the h1 = hgload figure object that I load from a file?

[Matt J]

   h1=hgload(...)
   hleg=findobj(h1,'Type','Legend');

   s6 = subplot(2,3,3);
   legend(hleg.String{:});

Excellent, that worked! Thanks for your help, Matt.

h1 = hgload('file.fig');
leg_ax = findobj(h1,'type','axes','Tag','legend','-not','Tag','Colorbar');
figure
s6 = subplot(2,3,3);
copyobj(leg_ax,get(s6,'Parent'));

[Ashley Penna]

In 2013 the "leg_ax" line no longer works since a legend isn't an axes any longer.

The handles can not be used if the object is deleted
