i have two sets of data.
surge amplitude and tension magnitude. the time steps are different but the time for both starts at 0 to 10800 s.
i am trying to have a n animated plot of both data (surge and tension)

Have a read here and here. It will greatly improve your chances of getting an answer.
What have you tried? What is your specific question?

Hi,
To animate a plot, I wrote the below code but does not work. I do not know much about MATLAB coding. How can I write a code to animate a multiplot (surge and tension).
t = TIME1;
y = tension;
t2 = TIME2;
y2 = surge;
For k = 1:length(t)
k2 = 1:length(t2)
%% marker plots
plot(t(k),y(k),'x')
hold on
plot(t2(k2),y2(k2),'o')
hold on
%% line plots
plot(t(1:k),y(1:k))
hold on
plot(t2(1:k2),y2(1:k2))
if k ~= length(t)
k2 ~= length(t2)
clf
end
end

Let (t1,x1) and (t2,x2) be your data. Where x1 is surge and x2 is tension. Both t1, t2 are in same intervel.
First let's get them to same time t1 using interpolation.
x2 = interp1(t2,x2,t1) ;
Now you can plot them.
for t = 1:length(t1)
plot(t1(1:t),x1(1:t),'r',t2(1:t),x2(1:t),'b') ;
drawnow
pause
end
You can also use set, this will be the good option. Read about it.
You can save the animation into a gif using this link: https://in.mathworks.com/matlabcentral/answers/94495-how-can-i-create-animated-gif-images-in-matlab

end
Also have a look on comet.

Thanks, it still does not work.
By having the data I have sent to you, how do you write the complete code which creates an animated line of surge or tension.
