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 theXYPlot
class, you don't normally need to call this method directly.- Specified by:
draw
in interfaceXYAnnotation
- Specified by:
draw
in classAbstractXYAnnotation
- 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
in classAbstractXYAnnotation
- Parameters:
obj
- the object (null
permitted).- Returns:
- A boolean.
-
hashCode
Returns a hash code for this object.- Overrides:
hashCode
in classAbstractXYAnnotation
- Returns:
- A hash code.
-
clone
Returns a clone of the annotation.- Specified by:
clone
in interfacePublicCloneable
- Overrides:
clone
in classAbstractAnnotation
- Returns:
- A clone.
- Throws:
