I was wondering if anyone knew how to do an animation plot of x = (dataset of 1000 points) y = (dataset of 1000 points) plot(x,y)

big problem is these are datasets

Answer 1

Since R2014b, you can work with annimatedline object (doc and how-to) that is meant to handle animated graphs pretty well. Basically, the annimatedline object has a addpoints function that adds new points to the line without having to redefine the existing points, along with a clearpoints function that clears lines for more complex animations.

Here is an example:

h = animatedline;
axis([0,4*pi,-1,1])

x = linspace(0,4*pi,1000);
y = sin(x);
for k = 1:length(x)  
    addpoints(h,x(k),y(k));
    drawnow
end
