Constructor Details

XYTextAnnotation

public XYTextAnnotation(String text,
double x,
double y)

Creates a new annotation to be displayed at the given coordinates. The coordinates are specified in data space (they will be converted to Java2D space for display).

Parameters:

text - the text.

x - the x-coordinate.

y - the y-coordinate.

Method Details

getX

public double getX()

Returns the x coordinate for the text anchor point (measured against the domain axis).

Returns:

The x coordinate.

setX

public void setX(double x)

Sets the x coordinate for the text anchor point (measured against the domain axis).

Parameters:

x - the x coordinate.

getY

public double getY()

Returns the y coordinate for the text anchor point (measured against the range axis).

Returns:

The y coordinate.

setY

public void setY(double y)

Sets the y coordinate for the text anchor point (measured against the range axis).

Parameters:

y - the y coordinate.

draw

public void draw(Graphics2D g2,
XYPlot plot,
Rectangle2D dataArea,
ValueAxis domainAxis,
ValueAxis rangeAxis)

Draws the annotation.

Specified by:

draw in interface XYAnnotation

Parameters:

g2 - the graphics device.

plot - the plot.

dataArea - the data area.

domainAxis - the domain axis.

rangeAxis - the range axis.

clone

public Object clone()
             throws CloneNotSupportedException

Returns a clone of the annotation.

Returns:

A clone.

Throws:

CloneNotSupportedException - if the annotation can't be cloned.
