Hi, All!
Say i have 2 variable, x1 and x2. I wanna plot (x1, x2) and animate it over time. i've tried this code:
x = [1 2;2 1;3 1;1 2;2 1;3 2];
x1 = x(1:end,1);
x2 = x(1:end,2);
r=animatedline;
for t=1:1000
for i=1:6
x1(i,t+1)=x1(i,t)+3;
x2(i,t+1)=x2(i,t)+x1(i,t);
end
addpoints(r,x1(1,:),x2(1,:))
addpoints(r,x1(2,:),x2(2,:))
drawnow
end
But that's not what i meant. From code above, the first line move from (1,2) to (4,3) to (7,7).... the second line move from (2,1) to (5,3), to (8,8),...
till the figure show the movement of those 6 lines.

I dont understand what you want to do. Do you want to animate six or two lines?

Here's one way to do it following the instructions on the Line Animations documentation page. I reduced the number of points to 100.
x = [1 2 3 1 2 3];
y = [2 1 1 2 1 2];
l1 = animatedline;
l2 = animatedline;
l3 = animatedline;
l4 = animatedline;
l5 = animatedline;
l6 = animatedline;
axis([0 150 0 1500])
for t = 1:100
if t>1
x(t,:)=x(t-1,:)+3;
y(t,:)=y(t-1,:)+x(t,:);
end
addpoints(l1,x(t,1),y(t,1))
addpoints(l2,x(t,2),y(t,2))
addpoints(l3,x(t,3),y(t,3))
addpoints(l4,x(t,4),y(t,4))
addpoints(l5,x(t,5),y(t,5))
addpoints(l6,x(t,6),y(t,6))
drawnow limitrate
end
