      org.jfree.chart.labels.StandardPieSectionLabelGenerator

StandardPieSectionLabelGenerator
public class StandardPieSectionLabelGenerator extends AbstractPieItemLabelGenerator implements PieSectionLabelGenerator,Cloneable,Serializable(Code)
A standard item label generator for plots that use data from a PieDataset .

For the label format, use {0} where the pie section key should be inserted, {1} for the absolute section value and {2} for the percent amount of the pie section, e.g. "{0} = {1} ({2})" will display as apple = 120 (5%).



Field Summary
final public static  StringDEFAULT_SECTION_LABEL_FORMAT
     The default section label format.

Constructor Summary
public  StandardPieSectionLabelGenerator()
     Creates a new section label generator using StandardPieSectionLabelGenerator.DEFAULT_SECTION_LABEL_FORMAT as the label format string, and platform default number and percentage formatters.
public  StandardPieSectionLabelGenerator(String labelFormat)
     Creates a new section label generator using the specified label format string, and platform default number and percentage formatters.
public  StandardPieSectionLabelGenerator(String labelFormat, NumberFormat numberFormat, NumberFormat percentFormat)
     Creates an item label generator using the specified number formatters.

Method Summary
public  Objectclone()
     Returns an independent copy of the generator.
public  booleanequals(Object obj)
     Tests the generator for equality with an arbitrary object.
Parameters:
  obj - the object to test against (null permitted).
public  AttributedStringgenerateAttributedSectionLabel(PieDataset dataset, Comparable key)
     Generates an attributed label for the specified series, or null if no attributed label is available (in which case, the string returned by StandardPieSectionLabelGenerator.generateSectionLabel(PieDataset,Comparable) will provide the fallback).
public  StringgenerateSectionLabel(PieDataset dataset, Comparable key)
     Generates a label for a pie section.
Parameters:
  dataset - the dataset (null not permitted).
Parameters:
  key - the section key (null not permitted).
public  AttributedStringgetAttributedLabel(int section)
     Returns the attributed label for a section, or null if none is defined.
Parameters:
  section - the section index.
public  voidsetAttributedLabel(int section, AttributedString label)
     Sets the attributed label for a section.

Field Detail
DEFAULT_SECTION_LABEL_FORMAT
final public static String DEFAULT_SECTION_LABEL_FORMAT(Code)
The default section label format.




Constructor Detail
StandardPieSectionLabelGenerator
public StandardPieSectionLabelGenerator()(Code)
Creates a new section label generator using StandardPieSectionLabelGenerator.DEFAULT_SECTION_LABEL_FORMAT as the label format string, and platform default number and percentage formatters.



StandardPieSectionLabelGenerator
public StandardPieSectionLabelGenerator(String labelFormat)(Code)
Creates a new section label generator using the specified label format string, and platform default number and percentage formatters.
Parameters:
  labelFormat - the label format (null not permitted).



StandardPieSectionLabelGenerator
public StandardPieSectionLabelGenerator(String labelFormat, NumberFormat numberFormat, NumberFormat percentFormat)(Code)
Creates an item label generator using the specified number formatters.
Parameters:
  labelFormat - the label format string (null not permitted).
Parameters:
  numberFormat - the format object for the values (nullnot permitted).
Parameters:
  percentFormat - the format object for the percentages (null not permitted).




Method Detail
clone
public Object clone() throws CloneNotSupportedException(Code)
Returns an independent copy of the generator. A clone.
throws:
  CloneNotSupportedException - should not happen.



equals
public boolean equals(Object obj)(Code)
Tests the generator for equality with an arbitrary object.
Parameters:
  obj - the object to test against (null permitted). A boolean.



generateAttributedSectionLabel
public AttributedString generateAttributedSectionLabel(PieDataset dataset, Comparable key)(Code)
Generates an attributed label for the specified series, or null if no attributed label is available (in which case, the string returned by StandardPieSectionLabelGenerator.generateSectionLabel(PieDataset,Comparable) will provide the fallback). Only certain attributes are recognised by the code that ultimately displays the labels:
Parameters:
  dataset - the dataset (null not permitted).
Parameters:
  key - the key. An attributed label (possibly null).



generateSectionLabel
public String generateSectionLabel(PieDataset dataset, Comparable key)(Code)
Generates a label for a pie section.
Parameters:
  dataset - the dataset (null not permitted).
Parameters:
  key - the section key (null not permitted). The label (possibly null).



getAttributedLabel
public AttributedString getAttributedLabel(int section)(Code)
Returns the attributed label for a section, or null if none is defined.
Parameters:
  section - the section index. The attributed label.



setAttributedLabel
public void setAttributedLabel(int section, AttributedString label)(Code)
Sets the attributed label for a section.
Parameters:
  section - the section index.
Parameters:
  label - the label (null permitted).
