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

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

Thank you very much these have both been very helpful as I am just starting up in the matlab world.

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.

You might want to check out:

doc animatedline

Example from the documentation:

Create the initial animated line object. Then, use a loop to add 1,000 points to the line. After adding each new point, use drawnow to display the new point on the screen.

h = animatedline;
axis([0,4*pi,-1,1])

x = linspace(0,4*pi,1000);
y = sin(x);
for k = 1:length(x)
    addpoints(h,x(k),y(k));
    drawnow
end

(And you can control the drawing speed up to a certain degree by resourcing to the pause command)
