Hi, I have vector which length is 120798 and I want to plot it on graph continuously in time. For example, I want to have 15 seconds of signal on the plot all the time. Is there any way to do this?

Consider the following approach:
A=randi([1 5],1,120798); %this is demo data, you will use your own data instead of this
Tend=15; %you want to plot for 15 seconds
t=0:Tend/numel(A):Tend-(Tend/numel(A));
plot(t,A)
Hope this helps.

Thanks for your answer. Can you tell me please what is 'val' in your code?
