Class Overview

A simple line annotation that can be placed on an XYPlot.

Summary

Public Constructors
XYLineAnnotation(double x1, double y1, double x2, double y2)
Creates a new annotation that draws a line from (x1, y1) to (x2, y2) where the coordinates are measured in data space (that is, against the plot's axes).
XYLineAnnotation(double x1, double y1, double x2, double y2, Stroke stroke, Paint paint)
Creates a new annotation that draws a line from (x1, y1) to (x2, y2) where the coordinates are measured in data space (that is, against the plot's axes).
Public Methods
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.
int hashCode()
Returns a hash code.

public XYLineAnnotation (double x1, double y1, double x2, double y2)

Creates a new annotation that draws a line from (x1, y1) to (x2, y2) where the coordinates are measured in data space (that is, against the plot's axes).

Parameters
x1 the x-coordinate for the start of the line.
y1 the y-coordinate for the start of the line.
x2 the x-coordinate for the end of the line.
y2 the y-coordinate for the end of the line.

public XYLineAnnotation (double x1, double y1, double x2, double y2, Stroke stroke, Paint paint)

Creates a new annotation that draws a line from (x1, y1) to (x2, y2) where the coordinates are measured in data space (that is, against the plot's axes).

Parameters
x1 the x-coordinate for the start of the line.
y1 the y-coordinate for the start of the line.
x2 the x-coordinate for the end of the line.
y2 the y-coordinate for the end of the line.
stroke the line stroke (null not permitted).
paint the line color (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 XYPlot class, you won't normally need to call it yourself.

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 to test against (null permitted).
Returns
  • true or false.

public int hashCode ()

Returns a hash code.

Returns
  • A hash code.
