Hi,

You can utilize “openfig()” for the purpose of opening a figure.

“openfig()” by default opens the figure. The below approach shows how to merge 3 figures, but it also opens other individual figures themselves.

Here ‘fig1.fig’, ‘fig2.fig’ and ‘fig3.fig’ are 3 sample figures.

close all; 
h(1) = openfig('fig1.fig'); 
h(2) = openfig('fig2.fig'); 
h(3) = openfig('fig3.fig'); 
hold on; 
title('Final Merged Figure'); 
plot(h(1).Children.Children.XData, h(1).Children.Children.YData); 
plot(h(2).Children.Children.XData, h(2).Children.Children.YData); 
plot(h(3).Children.Children.XData, h(3).Children.Children.YData); 
hold off; 

If you do not want to see the plots of the individual figures, you can pass the parameter ‘invisible’ to “openfig()”.

close all; 
h(1) = openfig('fig1.fig', 'invisible'); 
h(2) = openfig('fig2.fig', 'invisible'); 
h(3) = openfig('fig3.fig', 'invisible'); 
hold on; 
k = gcf; 
k.Visible = 'on'; 
title("Final Merged Figure"); 
plot(h(1).Children.Children.XData, h(1).Children.Children.YData); 
plot(h(2).Children.Children.XData, h(2).Children.Children.YData); 
plot(h(3).Children.Children.XData, h(3).Children.Children.YData); 
hold off;
