Hello all,
I do have two figures output from the matlab code (with the same axis unit) and i would like to keep both figures in the one single figure only. How can i do that ?
For example, you can refer two figures as attached
Thanks

Is there a particular reason you're @-mentioning me? It doesn't look like you're stuck with the people already helping you in this thread.

Don't call figure. Call subplot instead
subplot(1, 2, 1);
plot(x1, y1);
subplot(1, 2, 2);
plot(x2, y2);

@Image Analyst, i have only saved image in mat format (I do not have x1, y1, x2 and y2). So i do not know, how to merge the two figures. Also, i am afraid that subplot will show two different plot in one figure but i need only one figure with only one x and y axis. You can see the attached merged figure 1 and 2.
Can you please tell me how to merge the figures into the one figure.
Thank you very much in advance
Esila

Ran in:
tiledlayout(2,1)
nexttile
scatter(rand(10,1),rand(10,1),'sr')
nexttile
scatter(rand(10,1),rand(10,1),'gh')
You can also use the hold function.
figure
scatter(rand(10,1),rand(10,1),'sr')
hold on
scatter(rand(10,1),rand(10,1),'gh')
If you want to merge the two figures you have into one plot:
fig1 = openfig('Figure 1.fig');
fig2 = openfig('Figure 2.fig');
for ii = length(fig1.Children.Children):-1:1
fig1.Children.Children(ii).Parent=fig2.Children;
end

Do you have the x and y values for each figure? You should have them before you created and save the figure. Can you post the x and y values in a .mat file?

@Esila Darci I did merge Figure 1 and Figure 2. Since both figures had the same datapoints, you cannot notice the change without looking at the figure handle.
Below you can see Figure 1 and Figure 2 are the same.
openfig('Figure 1.fig');
xlim([-0.1 0.2])
ylim([-0.04 .16])
openfig('Figure 2.fig');
xlim([-0.1 0.2])
ylim([-0.04 .16])
Now I'm going to change the colors of all the lines in Figure 2 to green.
fig = openfig('Figure 2.fig');
for ii = length(fig.Children.Children):-1:1
fig.Children.Children(ii).Color = 'g';
end
xlim([-0.1 0.2])
ylim([-0.04 .16])
This is what Figure 3 looks like
openfig('Figure 3.fig');
xlim([-0.1 0.2])
ylim([-0.04 .16])
I will now take points from Figure 2 and Figure 3 and place them on Figure 4.
fig2 = openfig('Figure 2.fig');
for ii = length(fig2.Children.Children):-1:1
fig2.Children.Children(ii).Color = 'g';
end
fig3 = openfig('Figure 3.fig');
fig4 = figure;
axes;
% Moving Figure 3 lines to Figure 4
for ii = length(fig3.Children.Children):-1:1
fig3.Children.Children(ii).Parent = fig4.Children;
end
% Moving Figure 2 lines to Figure 4
for ii = length(fig2.Children.Children):-1:1
fig2.Children.Children(ii).Parent = fig4.Children;
end
% Remove empty figures
delete(fig2)
delete(fig3)
