All Implemented Interfaces:

PointRenderer

public class RectangularPointRenderer
extends AbstractPointRenderer

A point renderer that draws a rectangle for each of its points. For this renderer, the width and height of each rectangle is taken from the 3rd and 4th dimension of the chart point (a ChartableND) of the ChartModel. In other words you can easily configure the size of each point individually.
