Method Detail

draw

public void draw(java.awt.Graphics2D g2,
                 XYPlot plot,
                 java.awt.geom.Rectangle2D dataArea,
                 ValueAxis domainAxis,
                 ValueAxis rangeAxis,
                 int rendererIndex,
                 PlotRenderingInfo info)
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
Specified by:
draw in class AbstractXYAnnotation
Parameters:
g2 - the graphics device.
plot - the plot.
dataArea - the data area.
domainAxis - the domain axis.
rangeAxis - the range axis.
rendererIndex - the renderer index.
info - if supplied, this info object will be populated with entity information.

equals

public boolean equals(java.lang.Object obj)
Tests this object for equality with an arbitrary object.

Overrides:
equals in class AbstractXYAnnotation
Parameters:
obj - the object (null permitted).
Returns:
A boolean.

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException
Returns a clone of the annotation.

Returns:
A clone.
Throws:
java.lang.CloneNotSupportedException - if the annotation can't be cloned.
