Class XYLineAnnotation

Implemented Interfaces:
Cloneable, PublicCloneable, Serializable, XYAnnotation
public class XYLineAnnotation
extends AbstractXYAnnotation
implements Cloneable, PublicCloneable, Serializable
A simple line annotation that can be placed on an XYPlot.

Constructor Summary

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).

Method Summary

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.

XYLineAnnotation

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.

XYLineAnnotation

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).

Method Details

clone

public Object clone()
            throws CloneNotSupportedException
Returns a clone of the annotation.
Returns:
A clone.

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 XYPlot class, you won't normally need to call it yourself.
Specified by:
draw in interface XYAnnotation
Overrides:
draw in interface AbstractXYAnnotation
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 interface AbstractXYAnnotation
Parameters:
obj - the object to test against (null permitted).
Returns:
true or false.

hashCode

public int hashCode()
Returns a hash code.
Overrides:
hashCode in interface AbstractXYAnnotation
Returns:
A hash code.
