How to plot different iterations with a time delay in for loop?

Hi,

I am having some trouble plotting different iterations with a time delay of for example one second in my loop:

load Data_SATP.mat   
Days_SATP = Data_SATP([1:101:3131],[2]);    
L_ATP = Data_SATP([2:101],[1]);        
for j = 1:31
  Sw = Data_SATP([(2+(101*(j-1))):(101*j)],[2]);
  mat(j,:)=Sw           
end

figure(2)
for k=(1:31);
  plot(L_ATP,mat((1:31),:))
end

after which I fix the labels and axis. Now I get one plot of 31 graphs, but I would like to make the graphs appear one after each other in the same plot, preferably as an animated plot, but otherwise at least in the order of graph1, 1 second later graph2, etc.. I tried with pause(1), and I got it working once but after that I couldn't get it to work again after I changed some things, so advice on that is also welcome.

Thanks

The body of the FOR loop over k does not depend ob k at all. I guess, that you want mat(k, :):

H = plot(L_ATP,mat(1, :))
for k = 2:31
  pause(0.5);
  set(H, 'YData', mat(k, :));
end

I have another question related to this, I used the advice you gave me and now a part of it consists of this:

clc;
close all;
clear all;
load CS1.mat     

Days_SATP=              CS1([1:21:189],[2]);    
L_ATP=                  CS1([2:21],[1]);         

for j=(1:9);                               
Sw=                  CS1([(2+(21*(j-1))):(21*j)],[2]);  
mat(j,:)=Sw;            

end
figure;
H = plot(L_ATP,mat(1, :));
title('Aqueous phase')
xlabel('Length (-)')
ylabel('Saturation')
axis([0 1 0 1])
for k = 2:9
  pause(0.5);
  set(H, 'YData', mat(k, :));
end

load CS2.mat
for j=(1:9);                               
Sw=                  CS2([(2+(21*(j-1))):(21*j)],[2]); 
mat(j,:)=Sw;            

end
figure;
H = plot(L_ATP,mat(1, :));
title('Aqueous phase')
xlabel('Length (-)')
ylabel('Saturation')
axis([0 1 0 1])
for k = 2:9
  pause(0.5);
  set(H, 'YData', mat(k, :));
end

which gives me two plots after each other for a different data set. How can I plot both the data of CS1 and CS2 simultaneously in one figure?

I tried the following, with different tries for the set(...) part, but I can't figure it out:

clc;
close all;
clear all;
load CS1.mat
load CS2.mat

Days_SATP=              CS1([1:21:189],[2]);   
L_ATP=                  CS1([2:21],[1]);      

for j=(1:9);                             
Sw=                  CS1([(2+(21*(j-1))):(21*j)],[2]); 
mat(j,:)=Sw;             
Sw2=                  CS2([(2+(21*(j-1))):(21*j)],[2]); 
mat2(j,:)=Sw2;                   
end
figure;
H = plot(L_ATP,mat(1, :));
H2 = plot(L_ATP,mat2(1, :));

title('Aqueous phase')
xlabel('Length (-)')
ylabel('Saturation')
axis([0 1 0 1])
for k = 2:9
  pause(0.5);
  set(H, 'YData', mat(k, :),H2,'YData', mat2(k,:));
end
