How do I do two animated lines in two different figures?

Hi everyone. I need to do two different animated figures, but it turns out that I can only make up a single plot with two animated lines. Is there any solution to this problem? For example I tried couple different methods, but none of them worked:

clear all
close all
clc
[figure(1),figure(2)]=deal(animatedline);
x=0:1000;
y1=0:2:2000;
y2=0:4:4000;

for k=1:length(x)
    addpoints(figure(1),x(k),y1(k));
    axis([0,1000,0,2000]);
    drawnow
end

for k=1:length(x)
    addpoints(figure(2),x(k),y2(k));
    axis([0,1000,0,4000]);
    drawnow
end

The one above gives me both lines animated, one after another, but still in the same figure.

This 2nd one draws at the same moment:

clear all
close all
clc
h=animatedline
b=animatedline
x=1:1000;
y1=2:2:2000;
y2=4:4:4000;

for k=1:length(x)
    addpoints(h,x(k),y1(k));
    addpoints(b,x(k),y2(k));
    drawnow
end

And the 3rd one goes crazy at all:

clear all
close all
clc
[figure(1),figure(2)]=deal(animatedline);
x=1:1000;
y1=2:2:2000;
y2=4:4:4000;

for k=1:length(x)
    addpoints(figure(1),x(k),y1(k));
    addpoints(figure(2),x(k),y2(k));
    drawnow
end

The last one connects both lines and makes up one polyline. How can I avoid these problems? Is there any way I can make two different figures? And why is it when I assign h and b to be animatedline separately, it gives me two proper lines, whereas when I use [h,b]=deal(animatedline) function it gives me polyline? Thanks in advance!

Did you look at the documentation for animatedline? Like all plotting functions it allows you to specify an axes on which to plot, which I strongly recommend doing in all usage other than quick command line testing.

h = animatedline(ax,___)

is the relevant documentation line so simply

figure; hAxes(1) = gca;
hAnimatedLine(1) = animatedline( hAxes(1),... )

figure; hAxes(2) = gca;
hAnimatedLine(2) = animatedline( hAxes(2),... )

will give you two animated lines on two different figures. Equally you could create 2 distinct axes on the same figure and plot to those.
