comet3

3-D comet plot

Syntax

comet3(z)
comet3(x,y,z)
comet3(x,y,z,p)
comet3(axes_handle,...)

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.

comet3(z) displays a 3-D comet graph of the vector z.

comet3(x,y,z) displays a comet graph of the curve through the points [x(i),y(i),z(i)].

comet3(x,y,z,p) specifies a comet body of length p*length(y). p must be between 0 and 1.

comet3(axes_handle,...) plots into the axes with the handle axes_handle instead of into the current axes (gca).

Examples

Create a 3-D comet graph.

t = -10*pi:pi/250:10*pi;
comet3((cos(2*t).^2).*sin(t),(sin(2*t).^2).*cos(t),t);

Tips

The trace left by comet3 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 (for example, by resizing the window).
