I made a 2D color plot, how do I turn the plot into an animation or video of the points being put into place? Thanks

Asked by Union Colleg on 17 Jul 2013

The plots differ in color based on the Z value.

hi,

If you mean you have a plot from 2 vectors x and y, then you can use the function pause to drawn each point :

 for n=1:length(x)
        plot(x(n),y(n))
        pause(N),    % where N is numbers of seconds
        hold on,
 end

Here is an example from my File Exchange : http://www.mathworks.com/matlabcentral/fileexchange/41579-projectile-motion-in-weak-gravitational-fieldg=3-71-ms%C2%B2

The comet function is also quite nice.

    X = sin(0:.01:2*pi);
    comet(X)
%or
  X = sin(0:.01:2*pi);
  Y = 0:.01:2*pi;
  comet(X,Y)

Yes, though it could be even better if there were some way to control the speed of the comet and length of the tail.
