Hello,
Please, I am trying to use one super title for multiple subplots. I used annotation to accomplish that. The annotation is inside a loop. The problem is the annotation working fine when its not dynamic but unfortunately, I need to change title when I use Loop
I used below code which is working when there is no change on title.(This is just an example of random numbers)
clc;
clear;
a=rand(10,10);
for i=1:3
h(1)=subplot (2,2,1);
plot (a(:,1),a(:,2));
set(h(1),'Position',[.1 .35 .35 .5])
h(2)=subplot (2,2,2);
plot (a(:,1),a(:,2));
set(h(2),'Position',[.55 .35 .35 .5])
annotation('textbox', [0 0.85 1 0.1],'String',...
'Test text Number=1','EdgeColor', 'none','HorizontalAlignment', 'center')
end
I tried to change annotation line as below but it is not working
annotation('textbox', [0 0.85 1 0.1],'String',...
'Test text Number=%d',i,'EdgeColor', 'none','HorizontalAlignment', 'center')
I do not want to use external function in my code such as (suptitle,suplabel..etc)
Thanks

annotation doesn't have the facilities of sprintf, etc., you've got to build the string
annotation('textbox', [0 0.85 1 0.1],'String',...
num2str(i,'Test text Number=%d'),'EdgeColor', 'none','HorizontalAlignment', 'center')
