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 theXYPlot
class, you won't normally need to call it yourself.- 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
public boolean equals(Object obj)
Tests this object for equality with an arbitrary object.- Overrides:
equals
in classAbstractXYAnnotation
- Parameters:
obj
- the object to test against (null
permitted).- Returns:
true
orfalse
.
-
hashCode
public int hashCode()
Returns a hash code.- Overrides:
hashCode
in classAbstractXYAnnotation
- Returns:
- A hash code.
-
clone
public Object clone() throws CloneNotSupportedException
Returns a clone of the annotation.- Specified by:
clone
in interfaceorg.jfree.util.PublicCloneable
- Overrides:
clone
in classAbstractAnnotation
- Returns:
- A clone.
- Throws:
CloneNotSupportedException
- if the annotation can't be cloned.
