2-D comet plot

comet(y)
comet(x,y)
comet(x,y,p)
comet(ax,...)

## Description

comet(y) displays a comet graph of the vector y. A comet graph 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(x,y) displays a comet graph of vector y versus vector x.

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

comet(ax,...) plots into the axes ax instead of into the current axes (gca).

## Examples

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