Two line simple animation

Hello,

I have the following two lines plot. I want to animate both plots at the same time. I want to start from time 0 to time 9. I have tried the following code. For some reason

I don't understand it only plots the first plot only. How can also I save the animation to power point?

Thanks

GH

 clear all
  clc
  h=animatedline;
  axis([0,10,0,10]);

time=[0 1 2 3 4 5 6 7 8 9];
y1=[0 3 5 7 9 3 4 5 5 5];
y2=[0 1 3 4 5 1 3 4 4 4];

for k=1:length(time)
    addpoints(h,time(k),y1(k));
    drawnow
    hold on
    addpoints(h,time(k),y2(k));
    drawnow
    hold on
end

It seems you want two animated line objects.

h1=animatedline;
h2=animatedline;
axis([0,10,0,10]);

time=[0 1 2 3 4 5 6 7 8 9];
y1=[0 3 5 7 9 3 4 5 5 5];
y2=[0 1 3 4 5 1 3 4 4 4];

for k=1:length(time)
    addpoints(h1,time(k),y1(k));
    drawnow
    hold on
    addpoints(h2,time(k),y2(k));
    drawnow
    hold on
end

As for making the animation for powerpoint, you'll have to decide what video format to use. For a gif you can use my gif function.

You need to define animatedline for each line.

See if this does what you want:

h1=animatedline;
h2=animatedline;
axis([0,10,0,10]);

time=[0 1 2 3 4 5 6 7 8 9];
y1=[0 3 5 7 9 3 4 5 5 5];
y2=[0 1 3 4 5 1 3 4 4 4];

for k=1:length(time)
    addpoints(h1,time(k),y1(k));
    hold on
    addpoints(h2,time(k),y2(k));
    drawnow
end
hold off

Thanks for the answer. How can I change the color of the plots. I try

addpoints(h1,time(k),y1(k),'r');

However it didnt work. Any help will be appriciated.

Thanks

My pleasure.

You need to specify the color (and other options, if desired) in the animatedline call:

h1=animatedline('Color','r');

That will create a red line for ‘h1’.
