XYTitleAnnotation

public XYTitleAnnotation(double x,
                         double y,
                         Title title)

Creates a new annotation to be displayed at the specified (x, y) location.

Parameters:

x - the x-coordinate (in data space).

y - the y-coordinate (in data space).

title - the title (null not permitted).

XYTitleAnnotation

public XYTitleAnnotation(double x,
                         double y,
                         Title title,
                         RectangleAnchor anchor)

Creates a new annotation to be displayed at the specified (x, y) location.

Parameters:

x - the x-coordinate (in data space).

y - the y-coordinate (in data space).

title - the title (null not permitted).

anchor - the title anchor (null not permitted).

Method Detail

getCoordinateType

public XYCoordinateType getCoordinateType()

Returns the coordinate type (set in the constructor).

Returns:

The coordinate type (never null).

getX

public double getX()

Returns the x-coordinate for the annotation.

Returns:

The x-coordinate.

getY

public double getY()

Returns the y-coordinate for the annotation.

Returns:

The y-coordinate.

getTitle

public Title getTitle()

Returns the title for the annotation.

Returns:

The title.

getTitleAnchor

public RectangleAnchor getTitleAnchor()

Returns the title anchor for the annotation.

Returns:

The title anchor.

getMaxWidth

public double getMaxWidth()

Returns the maximum width.

Returns:

The maximum width.

setMaxWidth

public void setMaxWidth(double max)

Sets the maximum width and sends an AnnotationChangeEvent to all registered listeners.

Parameters:

max - the maximum width (0.0 or less means no maximum).

getMaxHeight

public double getMaxHeight()

Returns the maximum height.

Returns:

The maximum height.

setMaxHeight

public void setMaxHeight(double max)

Sets the maximum height and sends an AnnotationChangeEvent to all registered listeners.

Parameters:

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 the XYPlot class, you don't normally need to call this method directly.

Specified by:

draw in interface XYAnnotation

Specified by:

draw in class 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 class AbstractXYAnnotation

Parameters:

obj - the object (null permitted).

Returns:

A boolean.

hashCode

public int hashCode()

Returns a hash code for this object.

Overrides:

hashCode in class AbstractXYAnnotation

Returns:

A hash code.

clone

public Object clone()
             throws CloneNotSupportedException

Returns a clone of the annotation.

Specified by:

clone in interface PublicCloneable

Overrides:

clone in class AbstractAnnotation

Returns:

A clone.

Throws:

CloneNotSupportedException - if the annotation can't be cloned.
