How can I save a animated line into a video?

Hi, I'm trying to save this animated line into a video (mp4)? but I can't make it work.

can anyone help me?

Frames = (1:1:72868)';
h = animatedline;
axis([210,455,-100,140])

x = Frames(210:455,1);
y = accBallXY(210:455,1);
for k = 1:length(x)
    addpoints(h,x(k),y(k));
     pause(0.04)
    drawnow
end

Start with the getframe function and its firends, then see: Write Sequence of Images to Video.

That should get you started.

example:

% 阿基米德螺线
theta = 0:0.01:50;
y = theta.*exp(1i*theta);
figure();
h = animatedline(real(y(1)),imag(y(1)));
axis equal;
axis([-50,50,-50,50]);
axis off

[A,map] = rgb2ind(frame2im(getframe),256);
imwrite(A,map,'2.gif','LoopCount',65535,'DelayTime',0.01);
for k = 2:length(theta)
    addpoints(h,real(y(k)),imag(y(k)));
    drawnow
    if(mod(k,20)==0)
        [A,map] = rgb2ind(frame2im(getframe),256);
        imwrite(A,map,'2.gif','WriteMode','append','DelayTime',0.01);
    end
end
