Please add more description

[编辑]

This image, particularly since it is a graph, needs far more information. What are units of the scale ranges of the X and Y axes (radians?), what program was it made with, who made it, when, what does it illustrate? Which length does l in the equation refer to? It also needs a descriptive title. 'Chaotic motion of double pendulum system'? --Chetvorno 01:38, 2 May 2008 (UTC)[回复]
