Direct Known Subclasses:

Diamond, Triangle

public abstract class JCShape

extends Object

JCShape is an abstract base class used for defining custom point styles in JClass Chart. To create a new shape class, extend JCShape and provide a resize() method. The resize() method must populate the x[] and y[] arrays with point values for the shape to be drawn. The point values are relative to (0,0). Chart will automatically move the shape to the appropriate location.

Field Summary

protected int	size Size of the point.
protected int[]	x Array of x values.
protected int[]	y Array of y values.

Constructor Summary

JCShape()

Method Summary

void	draw(Graphics gc, double xorg, double yorg) Draws the point at the specified floating point pixel coordinates.
void	draw(Graphics gc, int xorg, int yorg) Draws the point at the specified integer pixel coordinates.
protected abstract void	resize(int sz) Populates the x[] and y[] arrays based on the provided size.
