I have got the following code which generates a number of images. I want to superimpose all the images that are generated from the loop. Can someone please help?

% 2D Plot Code
x = 1:44;
y = 1:44;
set(0,'defaultFigureVisible','off')
for i = 1:10
a = xlsread('JREF P1 air.xlsx',strcat('CO',int2str(46*i+3),':','EF',int2str(46*i+3)));
[xData, yData] = prepareCurveData( x, a );
ft = 'poly9';
[fitresult, gof] = fit( xData, yData, ft, 'Normalize', 'on' );
figure;
h = plot( fitresult,'m' );
title('Air Injection Pressure');
xlabel('X-Direction','FontSize',10);
ylabel('Pressure (kPa)','FontSize',10);
grid on;
axis([1 44 -5 60]);
set(gca,'TickDir','out');
grid off;
view(0,90);
fname = sprintf('2D %d.png',i);
fullFileName = fullfile('\\2D Plots',fname);
saveas(gcf,fullFileName);
end

I would suggest that it would be easier to save the fitting results and plot them all in one plot.

Inside your loop,

savedfits{i} = fitresult;

Then after your loop,

for i = 1 : 10
  plot(savedfits{i});
  L{i} = sprintf('file #%d', i);
  hold on
end
legend(L);
title('Air Injection Pressure');
xlabel('X-Direction','FontSize',10);
ylabel('Pressure (kPa)','FontSize',10);
grid on;
axis([1 44 -5 60]);
set(gca,'TickDir','out');
grid off;
view(0,90);
