Implemented Interfaces:
Cloneable, PublicCloneable, Serializable, XYAnnotation
public class XYShapeAnnotation
extends AbstractXYAnnotation
implements Cloneable, PublicCloneable, Serializable
A simple Shape annotation that can be placed on an XYPlot. The shape coordinates are specified in data space.

Constructor Summary

XYShapeAnnotation(Shape shape)
Creates a new annotation (where, by default, the shape is drawn with a black outline).
XYShapeAnnotation(Shape shape, Stroke stroke, Paint outlinePaint)
Creates a new annotation where the shape is drawn as an outline using the specified stroke and outlinePaint.
XYShapeAnnotation(Shape shape, Stroke stroke, Paint outlinePaint, Paint fillPaint)
Creates a new annotation.

Method Summary

clone()
Returns a clone.
void
draw(Graphics2D g2, XYPlot plot, Rectangle2D dataArea, ValueAxis domainAxis, ValueAxis rangeAxis, int rendererIndex, PlotRenderingInfo info)
Draws the annotation.
boolean

Method Details

clone

public Object clone()
            throws CloneNotSupportedException
Returns a clone.
Returns:
A clone.

draw

public void draw(Graphics2D g2,
                 XYPlot plot,
                 Rectangle2D dataArea,
                 ValueAxis domainAxis,
                 ValueAxis rangeAxis,
                 int rendererIndex,
                 PlotRenderingInfo info)
Draws the annotation. This method is usually called by the XYPlot class, you shouldn't need to call it directly.
Specified by:
draw in interface XYAnnotation
Overrides:
draw in interface 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 - the plot rendering info.

equals

public boolean equals(Object obj)
Tests this annotation for equality with an arbitrary object.
Overrides:
equals in interface AbstractXYAnnotation
Parameters:
obj - the object (null permitted).
Returns:
A boolean.

hashCode

public int hashCode()
Returns a hash code for this instance.
Overrides:
