comet (MATLAB Functions)

Two-dimensional comet plot

Syntax

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

Description

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(y) displays a comet graph of the vector y.

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(axes_handle,...) plots into the axes with handle axes_handle instead of the current axes (gca).

Remarks

Note that the trace left by comet is created by using an EraseMode of none, which means you cannot print the graph (you get only the comet head) and it disappears if you cause a redraw (e.g., by resizing the window).

Examples

Create a simple comet graph:

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