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)
