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{:})
