Parameters:

x - the x-coordinate (in data space).

y - the y-coordinate (in data space).

image - the image (null not permitted).

Method Details

draw

public void draw(Graphics2D g2,
XYPlot plot,
Rectangle2D dataArea,
ValueAxis domainAxis,
ValueAxis rangeAxis)

Draws the annotation. This method is called by the drawing code in the XYPlot class, you don't normally need to call this method directly.

Specified by:

draw in interface XYAnnotation

Parameters:

g2 - the graphics device.

plot - the plot.

dataArea - the data area.

domainAxis - the domain axis.

rangeAxis - the range axis.

equals

public boolean equals(Object object)

Tests this object for equality with an arbitrary object.

Overrides:

equals in class Object

Parameters:

object - the object (null permitted).

Returns:

A boolean.

clone

public Object clone()
             throws CloneNotSupportedException

Returns a clone of the annotation.

Returns:
