public abstract class Element

extends java.lang.Object

Immutable super class of a basic element of a chart. Each basic element has a perspective position and bounds in float precision. The element does not have a method to paint itself, it just contains the logic structure. For example an implementation of a 3D look is responsable to paint this element.
