Two-dimensional comet plot

comet
comet(y)
comet(x,y)
comet(x,y,p)

Description

A comet plot is an animated graph in which a circle (the comet head) traces the data points on the screen. The comet body is a trailing segment that follows the head. The tail is a solid line that traces the entire function.

comet

demonstrates the comet plot.

comet(y)

displays a comet plot of the vector y.

comet(x,y)

displays a comet plot of vector y versus vector x.

comet(x,y,p)

specifies a comet body of length p*length(y). p defaults to 0.1.

Examples

Create a simple comet plot:

t = 0:.01:2*pi;
x = cos(2*t).*(cos(t).^2);
y = sin(2*t).*(sin(t).^2);
comet(x,y);
