I want to combine 4 charts as per attached. The charts are extracted from running the attached code by changing K, C between 0 and 1. But the result shows 1 chart only. How to fix please?
Code to combine:
if true
fig = figure(10);
ax = axes(fig);
xlabel('\tau');
ylabel(' \Psi(0,\tau)');
title('Injection rate vs. K, C');
h1 = openfig('K0C0.fig','reuse');
h2 = openfig('K0C1.fig','reuse');
h3 = openfig('K1C0.fig','reuse');
h4 = openfig('K1C1.fig','reuse');
copyobj(h1.Children.Children,ax);
copyobj(h2.Children.Children,ax);
copyobj(h3.Children.Children,ax);
copyobj(h4.Children.Children,ax);
close(h1);
close(h2);
close(h3);
close(h4);
savefig('ratevsKC');
end
hold on
legend('K=0,C=0','K=0,C=1','K=1,C=0','K=1,C=1','location', 'southeast')
Combined result:

% GEt x and y data from figure

for i = 1:length(h1.Children.Children)

y1(i) = h1.Children.Children(i).YData ;
end
close(h1);
x2 = zeros(length(h2.Children.Children),1) ;
y2 = zeros(length(h2.Children.Children),1) ;
for i = 1:length(h2.Children.Children)
