hello everyone, i have this urgent problem

hello everyone, i have a problem about animating multi-sin waves,each of them is starts with different time(ex:sin1 starts with 0,sin2 starts with 1...etc),besides,the animation speed of them r different,can someone help me out,please? i really need to figure this out for my thesis ><

can you show something? The question is unclear

[Chia Ho Hsu]

like this, but i need the amplitude and the moving speed of 'O' and speed can be controllable,this is my code,i cant make it plot like the above photo i showed you:

clc;clear all;
t=0:0.1:100;
t2=1:0.5:100;
y=sin(t);
y2=sin(t2);
for k=1:length(t)
    plot(t(k),y(k),'X')
    hold on
    plot(t2(k),y2(k),'O')
     hold on
     
    plot(t(1:k),y(1:k))
    hold on
     plot(t2(1:k),y2(1:k))
     hold on
     
    axis([0 100 -1 1])
    grid on
    xlabel('t')
    ylabel('y')
    legend('servo degree', 'servo degree','servo 1','servo 2')
    pause(0.1)
    if k~=length(t)
        clf
    end
    if k~=length(t2)
        clf
    end
end

N = 1000;
t2 = linspace(0, 100, N);
t = t/5;

Do not use t = linspace(0,100) and then t2=t1*5 because if you do then t2 will escape the boundaries of the plot.

I discus one of the techniques in https://www.mathworks.com/matlabcentral/answers/496730-how-to-start-and-stop-parallel-timer-delays-on-off-delays-in-matlab#answer_406682

The other main possibility is to use timers, one for each simulation, with the timers firing each time each simulation is to advance to the next sample.

Answer 2

[Steven Lord]

t = 0:360;
h1 = animatedline('LineStyle', '-', 'Color', 'k');
h2 = animatedline('LineStyle', '--', 'Color', 'c');
axis([0 450 -1 1]);
for k = 1:numel(t)
    addpoints(h1, t(k), sind(t(k)));
    addpoints(h2, t(k)+90, sind(t(k)));
    pause((10/360))
end

While in this example I called addpoints on each of the animatedline objects at each iteration of the for loop, you could update each line only at certain iterations if you so desired.
