Combining multiple MATLAB figures in one plot

How can I merge the three different saved matlab figures (plots) in one graph?

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;

Hi,

I am trying to use your code but getting an error as

unrecognised method, property, or field 'XData' for class 'matlab.grapic.primitive.Data'.

Do you have any recomendation on that?

you can use my figure2subplot.m function to copy each figure to one subplot in the target figure.

check this link for the function :
