How can I plot multiple figures in one from multiple saved .fig files that have 2 figures but I only want 1 of them?

I have run multiple simulations of a system and in each run I changed one parameter. I saved the .fig files of a scope I am interested in but the scope plots 2 figures separated by the layout function (so there is one on top and one on the bottom part when you click/view the scope). How can I plot only the top figure (1st input in the scope) from the various .fig files that I saved? I want to highlight the difference when I change a specific parameter (increase and decrease) and repeat for each parameter that I changed.

Thank you a lot in advance!

It would help to have at least one of the .fig files to work with.

In general, use the openfig function to open each file. That creates a handle to it, and it should be relatively straightforward to get the line objects from it, using the findobj function. (I am not familiar with the various plotting functions the scope uses, so I hesitate to go further without one to experiment with.)

I would suggest findobj() axes instead of line objects.

It is not uncommon for scope plots to use specific Tags for the two different axes, so potentially you could findobj() based on tag.

Thank you both for your answers and you were right!

This morning I found this similar question so I managed to do what I wanted. Here is the link and the code for reference:

https://ch.mathworks.com/matlabcentral/answers/1842613-merge-3-fig-figures-into-one-graph

fig1 = openfig("fig1.fig");

fig2 = openfig("fig2.fig");

fig3 = openfig("fig3.fig");

L = findobj(fig1,'type','line');

copyobj(L,findobj(fig2,'type','axes'));

L2 = findobj(fig3,'type','line');

copyobj(L2,findobj(fig2,'type','axes'));
