MATLAB: How can i merge several subplot in one figure

subplot

Hi every one

I have several subplots like :

and i want to merge them such as:

could anyone help me to do that?

Thank you so much.

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)

You can just call the line "set(findobj(gcf,'type','axes'),'FontName','Calibri','FontSize',11,'FontWeight','Bold', 'LineWidth', 1,'layer','top');grid on" after all the subplots have been plotted as follows:

figure(1)
set(gcf,'position',[500 200 1000 600])
subplot(311)
stairs(A,B,'markersize',2,'marker','*','linewidth',1)
xlabel('Frequency (Hz)'),ylabel('Amplitude')
subplot(312)
stairs(C,D,'markersize',2,'marker','*','linewidth',1)
xlabel('Frequency (Hz)'),ylabel('Amplitude')
subplot(313)
plot(E,F,'MarkerSize',1,'LineWidth',1)
xlabel('Time [ms]'),ylabel('Amplitude')
set(findobj(gcf,'type','axes'),'FontName','Calibri','FontSize',11, ...
'FontWeight','Bold', 'LineWidth', 1,'layer','top');grid on

Here, "findobj(gcf,'type','axes')" will find all the axes which correspond to the current figure handle.

MATLAB: How can I combine several file.fig together

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')
