Hello, I am new to MATLAB. I have three MATLAB figures. I want to combine them to compare the data. Can someone help me doing this?

Both of those options as well as option #3 (which I just added) do exactly what you're describing. It sounds like you'd rather work with the previously created figures rather than with the code that produced the figures. If that's the case, option 2 and 3 are viable options, unless I'm not understanding the problem.
For option 2, you merely need to copy the line objects from 3 of the 4 figures on to the 4th figure (or copy objects from all 4 figs to a new figure). That can be done manually or programmatically (copyobj).
For option 3, you just need to get the handles to your line objects and then access the XData and YData (and ZData?). Then you can use those data to create a new plot. Note that depending on what you're plotting, you may want to access a different set of data from the handle.
If you need specific help with that, we'll need more info and perhaps a copy of the figure.

Hey, maybe you are reading this comment here. I have a kinda same problem i would say. First of all i am kinda new to Matlab. My problem is that i have 2 single Yagi Uda Antennas which i designed with putting data in (see Code) and these both Yagis I would like to combine in one Figure so that i can cross them and get at the End a crossed YagiUda which i can optimize with a Code, maybe you can help me or atleast tell me where i can look up for my Problem.
Best regards.
Code:
figure(2);
Numdirs = 1;
yagidesign_1 = yagiUda;
show(yagidesign_1)
figure(3);
yagidesign_2 = yagiUda;
yagidesign_2.NumDirectors = Numdirs;
yagidesign_2.ReflectorLength = RL;
yagidesign_2.DirectorLength = DL;
yagidesign_2.DirectorSpacing = d_Spaceing_2;
yagidesign_2.ReflectorSpacing = d_Spaceing;
yagidesign_2.Exciter.Length = EL
show(yagidesign_2)

I would save figures then plot them as subplots like this:
%First Figure
h1 = openfig('test1.fig','reuse'); % open figure
ax1 = gca; % get handle to axes of figure
%Second Figure
h2 = openfig('test2.fig','reuse');
ax2 = gca;
h3 = figure; %create new figure
s1 = subplot(1,2,1); %create and get handle to the subplot axes
s2 = subplot(1,2,2);
fig1 = get(ax1,'children'); %get handle to all the children in the figure
fig2 = get(ax2,'children');
copyobj(fig1,s1); %copy children to new parent axes i.e. the subplot axes
copyobj(fig2,s2);

@Tomer, meghannmarie 's demo above demonstrates my option #2.
h1 is the figure handle to test1.fig.
h1.Children will list the axes and any other object stored on that figure. If There's just 1 axes and nothing else, you can use this demo code directly. Otherwise you'll need to add an additional step to locate the axis (that's easy - we could help you with that). Then you want to get the children of the axis which will be the handles to any graphic objects stored on the axes. They will then be copied to the new axes.
