All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`AttributedString`	`generateAttributedSectionLabel(PieDataset<K> dataset, K key)`	Generates an attributed label for the specified series, or `null` if no attributed label is available (in which case, the string returned by `generateSectionLabel(PieDataset, Comparable)` will provide the fallback).
`String`	`generateSectionLabel(PieDataset<K> dataset, K key)`	Generates a label for a pie section.

- Method Detail
  - generateSectionLabel
```
String generateSectionLabel(PieDataset<K> dataset,
                            K key)
```
    Generates a label for a pie section.
    
    Parameters:
    
    dataset - the dataset (null not permitted).
    
    key - the section key (null not permitted).
    
    Returns:
    
    The label (possibly null).
  - generateAttributedSectionLabel
```
AttributedString generateAttributedSectionLabel(PieDataset<K> dataset,
                                                K key)
```
    Generates an attributed label for the specified series, or null if no attributed label is available (in which case, the string returned by generateSectionLabel(PieDataset, Comparable) will provide the fallback). Only certain attributes are recognised by the code that ultimately displays the labels:
    
    TextAttribute.FONT: will set the font;
    
    TextAttribute.POSTURE: a value of TextAttribute.POSTURE_OBLIQUE will add Font.ITALIC to the current font;
    
    TextAttribute.WEIGHT: a value of TextAttribute.WEIGHT_BOLD will add Font.BOLD to the current font;
    
    TextAttribute.FOREGROUND: this will set the Paint for the current
    
    TextAttribute.SUPERSCRIPT: the values TextAttribute.SUPERSCRIPT_SUB and TextAttribute.SUPERSCRIPT_SUPER are recognised.
    Parameters:
    
    dataset - the dataset.
    
    key - the key.
    
    Returns:
    
    An attributed label (possibly null).
