how can I combine several file.fig together

I have several files which their formats are.fig (actually they are graphs), I need to combine them together for comparison.

could you please help me which function I can use?

Can you attach some sample fig files so that we can see what type of graphs it contain.

[Niloufar Baba adam]

my files are same as these attaches.

If you built the figures and saved them; it would almost certainly be far easier to do the combining of those data then on a given axis/figure or via subplot() instead of going back and retrieving from the save .fig files.

We need more detail of what you did to get these .fig files (unless they were/are from an external source in which case unless very complicated figures having the raw data as .mat file(s) would also probably be simpler) and a much clearer explanation of what your end objective should be.

It's unclear whether you want to combine each line into the same axes or if you want to combine each axes into the same figure as a set of subplots.

This demo combines the lines from all axes into 1 axes and changes their colors and legend names. The axes will have the same properties as the first copied axes.

Assumptions:

1. Each figure contains only 1 axes
2. Each axes contains only 1 graphics object (ie, your blue lines).

If these assumptions aren't met slight adjustments will be needed to access the desired handles.

% List figures 
figureList = {'103_RU.fig','118_RU.fig'}; 
% List new line colors
lineCol = jet(numel(figureList)); 

% Open each figure and copy content
for i = 1:numel(figureList)
    % Open fig-i
    fighand = open(figureList{i});
    % Get axis handle (assumption: only 1 axes in figure)
    axHand = findobj(fighand, 'Type', 'Axes');
    
    % on first iteration only, create new figure and
    % copy the entire axis from fig-i
    if i==1
        fh = figure();
        newAxes = copyobj(axHand, fh);
        hold(newAxes, 'on')
        title(newAxes,'Combined RU')
        h = newAxes.Children; 
    else
        % copy content of axes
        h = copyobj(axHand.Children, newAxes);
    end
    
    % Set line color and displayname
    h.Color = lineCol(i,:); 
    h.DisplayName = axHand.Title.String;
    
    % Close fig-i
    close(fighand)
end

% Ceate legend
legend(newAxes, 'Interpreter', 'None')

thank you so much, this is the exactly what i want.

Glad I could help. I just added a few lines to the text of my answer expaining two important assumptions the code makes.
