I asked this question https://www.mathworks.com/matlabcentral/answers/1771360-if-for-loop-repeated-itself-many-times-can-i-plot-what-calculated-inside-for-loop-in-one-curve

and got the answer from @ Walter Roberson, but now I modified the question as in the code below,,Can I use the addpoints function to show me

x1(i), x2(i), x3(i), and x4(i)

in ONE figure BUT seperated (Splitted curves in one figure) ?

Thanks in advance

while 1
    for i=1:20
        x1(i)=something
        x2(i)=something
        x3(i)=something
        x4(i)=something
    end
    plot(x,i)
end

So you want multiple animated lines in the same figure? That's easy, just use multiple animatedline objects.

x = 0:360;
axis([0 360 -1 1]);
hold on
s = animatedline('Color', 'r', 'DisplayName', 'sine');
c = animatedline('Color', 'c', 'DisplayName', 'cosine');
legend show
for k = 1:numel(x)    
    addpoints(s, x(k), sind(x(k)));
    addpoints(c, x(k), cosd(x(k)));
    pause(0.01)
end
