How do i superimpose different MATLAB figures

Hi, i have these MATLAB figures and will like to superimpose them as one figure. Is there a line of code to achieve that? They both have same y and x limits

No, there is no line of code to achieve that. Merging of figures takes a bunch of work because of all of the special cases about menus and toolbars and callbacks (and because the two figures might have been created with different MATLAB releases with different support for graphics objects.)

In the simple case where you are willing to flub all of that:

 first_fig = figure(1);
 second_fig = figure(2);
 first_ax = findobj(first_fig, 'type', 'axes');
 second_ax = findobj(second_fig, 'type', 'axes')
 if length(first_ax) ~= 1 || length(second_ax) ~= 1
    error('this code requires the two figures to have exactly one axes each');
 end
 ch2 = get(second_ax, 'children');     %direct children only and don't try to find the hidden ones
 copyobj(ch2, first_ax);         %beam them over

Hi Walter, i tried modifying the code to superpose 3 figures but couldnt get through it. It worked perfectly for the 2 figures. Can you help out please

 first_fig = figure(1);   %adjust as needed
 second_fig = figure(2);  %adjust as needed
 third_fig = figure(3);   %adjust as needed
 first_ax = findobj(first_fig, 'type', 'axes');
 second_ax = findobj(second_fig, 'type', 'axes');
 third_ax = findobj(third_fig, 'type', 'axes');
 if length(first_ax) ~= 1 || length(second_ax) ~= 1 || length(third_ax) ~= 1
    error('this code requires the three figures to have exactly one axes each');
 end
 ch2 = get(second_ax, 'children');     %direct children only and don't try to find the hidden ones
 copyobj(ch2, first_ax);         %beam them over
 ch3 = get(third_ax, 'children');      %direct children only and don't try to find the hidden ones
 copyobj(ch3, first_ax);        %beam them over
