MATLAB: How can I combine several file.fig together

combine .fig files

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?

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:

Each figure contains only 1 axes
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')

MATLAB: How can i merge several subplot in one figure

It looks like you might be using a stackedplot which currently doesn't support adding objects to the axes after the plot is created. You can, however, plot multiple lines in each axis (see this answer).

Subplots and tiledlayouts do allow adding objects to the axes.

Option 1:

use hold(ax,'on') to hold the axes 'ax'.
use plot(ax,____) to plot on axes 'ax'

Option 2:

Copy a plotted line 'h' to axes 'ax' using copyobj(h,ax)

MATLAB: Combine fig files into 1 figure

Run this code

fig(1) = openfig('SARIMA_forecast.fig'); % open figure


fig(2) = openfig('VAR_forecast.fig'); % open figure
fig(3) = openfig('VECM_forecast.fig'); % open figure
new_fig = figure;
ax_new = gobjects(size(fig));
for i=1:3
    ax = subplot(3,1,i);
    ax_old = findobj(fig(i), 'type', 'axes');
    ax_new(i) = copyobj(ax_old, new_fig);
    ax_new(i).YLimMode = 'manual';
    ax_new(i).Position = ax.Position;
    ax_new(i).Position(4) = ax_new(i).Position(4)-0.02;
    delete(ax);
end
