All Implemented Interfaces:

Annotation

Direct Known Subclasses:

AutoPositionedLabel, ChartLabel

public abstract class AbstractLabel
extends AbstractAnnotation

A superclass of labels that can be added to a Chart.

The default font is taken from UIManager's Chart.font key value.

The default color is taken from UIManager's Chart.foreground key value

Constructor Summary

AbstractLabel()
Construct a label with no text (i.e., the empty string), default color and default font

AbstractLabel(String label)

AbstractLabel(String label, Color color)

AbstractLabel(String label, Color color, Font font)

AbstractLabel(String label, LabelStyle labelStyle)

Method Summary

boolean	equals(Object obj)
Color	getColor()
Font	getFont()
String	getLabel()
protected JLabel	getLabelComponent()
LabelStyle	getLabelStyle()
Double	getRotation()
int	hashCode()
void	paint(Graphics g, int x, int y, double rotation)
void	paint(Graphics g, int x, int y, Rotation rotation)
void	setColor(Color color)
void	setFont(Font font)
void	setLabel(String label)
void	setLabelStyle(LabelStyle labelStyle)
void	setRotation(Double rotation) Set the rotation of the label in radians, relative to the normal horizontal position; for example Math.PI/2 = 90 degrees clockwise -Math.PI/2 = 90 degrees anticlockwise Math.PI/4 = 45 degrees clockwise -Math.PI/4 = 45 degrees anticlockwise
Dimension	size(Graphics g, Font f) This method assumes that the font to be used for the label has already been set on the graphics context.

Method Detail

getLabel

public String getLabel()

setLabel

public void setLabel(String label)

getLabelComponent

protected JLabel getLabelComponent()

getColor

public Color getColor()

setColor

public void setColor(Color color)

getFont

public Font getFont()

setFont

public void setFont(Font font)

getRotation

public Double getRotation()

setRotation

public void setRotation(Double rotation)

Set the rotation of the label in radians, relative to the normal horizontal position; for example

• Math.PI/2 = 90 degrees clockwise
• -Math.PI/2 = 90 degrees anticlockwise
• Math.PI/4 = 45 degrees clockwise
• -Math.PI/4 = 45 degrees anticlockwise

Parameters:

rotation - the radians to rotate; positive values rotate clockwise, negative values anticlockwise

getLabelStyle

public LabelStyle getLabelStyle()

setLabelStyle

public void setLabelStyle(LabelStyle labelStyle)

size

public Dimension size(Graphics g,
                      Font f)

This method assumes that the font to be used for the label has already been set on the graphics context.

Parameters:

g - - the graphics context for which the size is to be calculated

Returns:

the dimension of the label in the supplied graphics context

paint

public void paint(Graphics g,
                  int x,
                  int y,
                  Rotation rotation)

paint

public void paint(Graphics g,
                  int x,
                  int y,
                  double rotation)

Parameters:

g - the Graphics object onto which the method draws

x - the x coordinate of the centre of the label

y - the y coordinate of the centre of the label

rotation - in radians

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object
