i use this code to cobine tow figures but i want help to make loop to combine more than tow figures

thnx

 fh1 = open('f1.fig');
 fh2 = open('f2.fig');
 ax1 = get(fh1, 'Children');
 ax2 = get(fh2, 'Children');
 ax2p = get(ax2(1),'Children');
 copyobj(ax2p, ax1(1));

Do you have the source data and scripts used to create the figure files? If you can plot a new figure using data set 1, then use the "hold on" command, and call plot again with data set 2. Call "hold off" when all data is added to one figure.

The plot function accepts a third parameter which specifies line type and marker, per this snippet from the documentation:

Various line types, plot symbols and colors may be obtained with

PLOT(X,Y,S) where S is a character string made from one element

from any or all the following 3 columns:

b blue . point - solid

g green o circle : dotted

r red x x-mark -. dashdot

c cyan + plus -- dashed

m magenta * star (none) no line

y yellow s square

k black d diamond

w white v triangle (down)

^ triangle (up)

< triangle (left)

> triangle (right)

p pentagram

h hexagram

For example, PLOT(X,Y,'c+:') plots a cyan dotted line with a plus

at each data point; PLOT(X,Y,'bd') plots blue diamond at each data

point but does not draw any line.

Assuming that each figure only has 1 axes and you want the first axes to be the one you want to copy into

fig(1) = open('f1.fig');
fig(2) = open('f2.fig');
fig(3) = open('f3.fig');
% ...
ax = findobj(fig(1),"Type","Axes");
% identify the axes of the first figure
for i = 2:numel(fig)
    PlotObjs = findobj(fig(i),"Type","Line","-or","Type","Scatter")
    copyobj(PlotObjs,ax)
end

If you want to re-do the markers, identify all the plot objects and re-set their linespec/colors.

PlotObjs = findobj(fig(1),"Type","Line","-or","Type","Scatter")
for i = 1:numel(PlotObjs)
    set(PlotObjs(i),"LineStyle",...)
    set(PlotObjs(i),"Marker",...)
    set(PlotObjs(i),"Color",...)
    % etc
end
