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)

thanks dear Adam

i use a code for single graphs (not subplot):

figureList = {'D-S13-0.fig','D-S13-15.fig','D-S13-30.fig','D-S13-45.fig'}; 
% List new line colors
lineCol = lines(numel(figureList)); 
% LineWidth = (20*unit::mm);
% 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,'S11')
        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;
    set (h,'linewidth',1)
   
    % Close fig-i
    close(fighand)
end
% Ceate legend
legend(newAxes,'original response','the effects of H3,5', 'the effect of H3','the effect of H5')

this is the same that you suggest me?

but this is not work for subplot, unfortunately.

What specifically isn't working?

Upon first glance, the code seems reasonable.

[Niloufar Baba adam]

there is an error in line:

h.DisplayName = axHand.Title.String;

[Niloufar Baba adam]

unfortunantly I'm not very good at programming, Thank you if you can help me

[Adam Danz]

The phrase "it's not working" doesn't convey much information.

axHand.Title.String - should be a string that matches the axis title (assuming the axis has a title).

h.DisplayName = axHand.Title.String; - should assign the axis title as the line object's DisplayName (which will appear in the legend).

When you use the DisplayName property (which is a good idea), you don't need to re-define the legend strings when you call legend().

This line

legend(newAxes,'original response','the effects of H3,5', 'the effect of H3','the effect of H5')

should just be

legend(newAxes)
