Class XYImageAnnotation
- Cloneable, PublicCloneable, Serializable, XYAnnotation
implements Cloneable, PublicCloneable, Serializable
An annotation that allows an image to be placed at some location on
an
XYPlot
.
TODO: implement serialization properly (image is not serializable).
XYImageAnnotation(double x, double y, Image image) - Creates a new annotation to be displayed at the specified (x, y)
location.

Object | clone() - Returns a clone of the annotation.
|
void | draw(Graphics2D g2, XYPlot plot, Rectangle2D dataArea, ValueAxis domainAxis, ValueAxis rangeAxis, int rendererIndex, PlotRenderingInfo info) - Draws the annotation.
|
boolean | equals(Object obj) - Tests this object for equality with an arbitrary object.

XYImageAnnotation
public XYImageAnnotation(double x,
double y,
Image image)
Creates a new annotation to be displayed at the specified (x, y)
location.
x
- the x-coordinate (in data space).y
- the y-coordinate (in data space).image
- the image (null
not permitted).
clone
public Object clone()
throws CloneNotSupportedException
Returns a clone of the annotation.
draw
public void draw(Graphics2D g2,
XYPlot plot,
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.
- draw in interface XYAnnotation
- draw in interface AbstractXYAnnotation
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(Object obj)
Tests this object for equality with an arbitrary object.
- equals in interface AbstractXYAnnotation
obj
- the object (null
permitted).
hashCode
public int hashCode()
Returns a hash code for this object.
