Dynamic graph of polygonial lines

Hi, I am trying to solve this issue for couple of weeks. I want to have a single 2d figure on which I will draw not-closed 3 polygonial lines of different colors.

So pseudocode should be something like this:

draw(path1,path2,path3);
for i=1:10
  path1=f1();
  path2=f2();
  path3=f3();
  draw(path1, path2, path3);

User should just watch it, without need to click anything.

Can you give me some hint, please.

Thank you

doc pause
doc drawnow

Example:

hold all
h1 = plot(rand(100,1));
h2 = plot(rand(100,1));
h3 =  plot(rand(100,1));
drawnow
hold off
for k=1:10
  set(h1,'ydata',rand(100,1))
  set(h2,'ydata',rand(100,1))
  set(h3,'ydata',rand(100,1))
  pause(0.5)
end

Thank you very much!

Is it possible to same-color lines be not-connected? Like in this picture: http://i51.tinypic.com/2wns3v8.png

Color of each line you can set as follows:

h = plot(rand(100,1),'Color',[1 0 0]);

for k=1:10

set(h,'Color',[k/10 1-k/10 0.5+k/20])

pause(0.5)

end
