Hi all,
I have a question about the merging of figures. I have 5 figures (.fig) consisting of 4 subplots (2x2). I want to merge these figures into one figure with the size of 6x4 where the first original figure will be placed in the left top (6,4,1/6,4,2/6,4,5/6,4,6), the second in the right top (6,4,3/6,4,4/6,4,7/6,4,8) and so on. I tried several things with copyobj and findobj, but did not manage to figure out how to actually merge the subplots.
Can anyone help me with this problem?
Thanks in advance!

Hi Lars,
I had written this code to extract data from a figure file. Hope few modification will work for you.
clear all;
close all;
clc;
x=0:0.01:3;
for ii=1:4
f(ii)=figure(ii);
for jj=1:4
subplot(2,2,jj),plot(x,x.^jj);
end
end
savefig(f(1),'testFig1');savefig(f(2),'testFig2');
savefig(f(3),'testFig3');savefig(f(4),'testFig4');
clear all;close all;clc
fig(1)=openfig('testFig1.fig');fig(2)=openfig('testFig2.fig');
fig(3)=openfig('testFig3.fig');fig(4)=openfig('testFig4.fig');
kk=1;
for ii=1:4
axObjs = fig(ii).Children;
for jj=1:length(axObjs)
dataObjs = axObjs(jj).Children;
x = dataObjs.XData;
y = dataObjs.YData;
figure(5),subplot(4,4,kk)
if(ishold==0)
hold on;
end
plot(x,y);
kk=kk+1;
end
end
