Public Constructors

public XYImageAnnotation (double x, double y, Image image)

Creates a new annotation to be displayed at the specified (x, y) location.

Parameters
x the x-coordinate (in data space).
y the y-coordinate (in data space).
image the image (null not permitted).

public XYImageAnnotation (double x, double y, Image image, RectangleAnchor anchor)

Creates a new annotation to be displayed at the specified (x, y) location.

Parameters
x the x-coordinate (in data space).
y the y-coordinate (in data space).
image the image (null not permitted).
anchor the image anchor (null not permitted).

Public Methods

public Object clone ()

Returns a clone of the annotation.

Returns
  • A clone.
Throws
CloneNotSupportedException if the annotation can't be cloned.

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.

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.

public boolean equals (Object obj)

Tests this object for equality with an arbitrary object.

Parameters
obj the object (null permitted).
Returns
  • A boolean.

public Image getImage ()

Returns the image for the annotation.

Returns
  • The image.

public RectangleAnchor getImageAnchor ()

Returns the image anchor for the annotation.

Returns
  • The image anchor.

public double getX ()

Returns the x-coordinate (in data space) for the annotation.

Returns
  • The x-coordinate.

public double getY ()

Returns the y-coordinate (in data space) for the annotation.

Returns
  • The y-coordinate.

public int hashCode ()

Returns a hash code for this object.

Returns
  • A hash code.
