Two-dimensional comet plot
Syntax
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(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
.
Remarks
Note that the trace left by comet
is created by using an EraseMode
of none
, which means you cannot print the plot (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 plot:
t = 0:.01:2*pi;
x = cos(2*t).*(cos(t).^2);
y = sin(2*t).*(sin(t).^2);
comet(x,y);
