MATLAB: How to merge two figures with multiple plots

multiple figureplot

Hello,
I have two figures (.fig file). These both figures have 4 plots in them (2×2 layout). I got them from two different Simulink models and want to make visual comparison of each plot. I've tried this code but it just merges one plot and other three plot spaces are left empty. Can someone help me?
     % Open old figures.
    gu = open('1.fig');
    gu_ax = gca;
    lu = open('2.fig');
    lu_ax = gca;
    F = figure; % New figure
    P1 = subplot(2,2,1); % Plot a subplot.
    P1_pos = get(P1,'position'); % get its position.
    delete(P1) % Delete the subplot
    P2 = subplot(2,2,2);
    P2_pos = get(P2,'position');
    delete(P2);
    P3 = subplot(2,2,3);
    P3_pos = get(P3,'position');
    delete(P3);
    P4 = subplot(2,2,4);
    P4_pos = get(P4,'position');
    delete(P4);
    P = copyobj(gu_ax,F); % Copy the gu_ax to new fig
    set(P,'position',P4_pos) % Set its position to the deleted subplot's
    P = copyobj(lu_ax,F);
    set(P,'position',P4_pos);

Best Answer

Hello Rokas,
Rather than copying the axes from the second figure, I think you could just copy the line objects or whatever else is on the axes. It would be easiest to just copy each of the Children of the axes object. Something like:
gu_axes = gu.Children; % Get all the axes on the first figure
lu_axes = lu.Children; % ... second figure
... % set up the new figure if you want to do it on a new figure ...
for k = 1:numel(gu_axes)
    copyobj(lu_axes(k).Children,gu_axes(k))
end
