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
