Hi, I have several pre-saved plots in format .fig and I want to combine them together with different colors. Any simple function or idea to deal with this? Thanks in advance

Why not use export_fig() and save them as PNG images, then you can use montage() to create an array of those images?

Thanks Image Analyst for your reply. Do you think my question is hard to understand? you have saved .fig files and you want them all combined in one figure, simple and plain. Anyway, open or openfig do not make them one, instead, open them in their own figures. I have solved the problem using the link:
https://www.mathworks.com/matlabcentral/answers/3901-merging-two-figures
This is how I solved for 5 figures: P1, P2 P3, P4, and P5.
figure(1) = openfig('P1.fig');
figure(2) = openfig('P2.fig');
figure(3) = openfig('P3.fig');
figure(4) = openfig('P4.fig');
figure(5) = openfig('P5.fig');
L3 = findobj(2,'type','line');
L4 = findobj(3,'type','line');
L5 = findobj(4,'type','line');
L6 = findobj(5,'type','line');
copyobj(L3,findobj(1,'type','axes'));
copyobj(L4,findobj(1,'type','axes'));
copyobj(L5,findobj(1,'type','axes'));
copyobj(L6,findobj(1,'type','axes'));
Thanks once again

Yes it wasn't clear. I'd thought you wanted to open them and "tile" them, like into quadrants.
I think rather than getting the lines out, you can get the data out of the axes with XData and then replot it. Maybe something like (untested):
f1 = openfig(filename1)
ax = gca;
x1 = ax.XData;
y1 = ax.YData;
plot(x1, y1, 'b-', 'LineWidth', 2);
and so on for the other figures to get x2, y2, x3, y3, etc.
Don't use figure as the name of a variable like you did because that's the name of an important built-in function. Call it myFigures or something instead of figure.
