- Method Detail
  - customInitialize
```
protected void customInitialize()
```
    Description copied from class: JRFillElementDataset
    
    Initializes the element dataset.
    The dataset is initialized before being used and after each time the dataset gets reset.
    
    Specified by:
    
    customInitialize in class JRFillElementDataset
    
    See Also:
    
    JRFillElementDataset.getDatasetResetType()
  - customEvaluate
```
protected void customEvaluate(JRCalculator calculator)
                       throws JRExpressionEvalException
```
    Description copied from class: JRFillElementDataset
    
    Evaluates the expressions associated with the dataset.
    Usually, the result of the evaluation would be preserved so that it is used in JRFillElementDataset.customIncrement()
    
    Specified by:
    
    customEvaluate in class JRFillElementDataset
    
    Parameters:
    
    calculator - used to evaluate expressions
    
    Throws:
    
    JRExpressionEvalException - any exception that occurs while evaluating expressions
  - evaluateSectionHyperlink
```
protected void evaluateSectionHyperlink(JRCalculator calculator)
                                 throws JRExpressionEvalException
```
    Throws:
    
    JRExpressionEvalException
  - customIncrement
```
protected void customIncrement()
```
    Description copied from class: JRFillElementDataset
    
    Increments the dataset by collecting the result of the expression evaluation.
    
    Specified by:
    
    customIncrement in class JRFillElementDataset
  - getCustomDataset
```
public org.jfree.data.general.Dataset getCustomDataset()
```
    Specified by:
    
    getCustomDataset in class JRFillChartDataset
  - getLabelGenerator
```
public Object getLabelGenerator()
```
    Specified by:
    
    getLabelGenerator in class JRFillChartDataset
  - getSeriesExpression
```
public JRExpression getSeriesExpression()
```
    Specified by:
    
    getSeriesExpression in interface JRHighLowDataset
    
    Returns:
    
    the expression of the series name. Currently only one series is supported inside a High-Low or Candlestick chart. This limitation is documented inside JFreeChart, the library used for the built-in chart support. However, this single series must be identified by a java.lang.Comparable value returned by this expression, and it must also be used as the series name in the chart's legend.
  - getDateExpression
```
public JRExpression getDateExpression()
```
    Specified by:
    
    getDateExpression in interface JRHighLowDataset
    
    Returns:
    
    the expression of the date to which the current (high, low, open, close, volume) item refers.
  - getHighExpression
```
public JRExpression getHighExpression()
```
    Specified by:
    
    getHighExpression in interface JRHighLowDataset
    
    Returns:
    
    a numeric expression that will be part of the data item added to the series when the dataset gets incremented.
  - getLowExpression
```
public JRExpression getLowExpression()
```
    Specified by:
    
    getLowExpression in interface JRHighLowDataset
    
    Returns:
    
    a numeric expression that will be part of the data item added to the series when the dataset gets incremented.
  - getOpenExpression
```

```
    Specified by:
    
    getOpenExpression in interface JRHighLowDataset
    
    Returns:
    
    a numeric expression that will be part of the data item added to the series when the dataset gets incremented.
  - getCloseExpression
```
public JRExpression getCloseExpression()
```
    Specified by:
    
    getCloseExpression in interface JRHighLowDataset
    
    Returns:
    
    a numeric expression that will be part of the data item added to the series when the dataset gets incremented.
  - getVolumeExpression
```
public JRExpression getVolumeExpression()
```
    Specified by:
    
    getVolumeExpression in interface JRHighLowDataset
    
    Returns:
    
    a numeric expression representing the volume value to use for the current data item. It is used only for Candlestick charts.
  - getDatasetType
```
public byte getDatasetType()
```
    Description copied from interface: JRChartDataset
    
    Gets the dataset type. Must be one of the dataset type constants defined in this class.

  - getItemHyperlink
```
public JRHyperlink getItemHyperlink()
```
    Description copied from interface: JRHighLowDataset
    
    Returns the hyperlink specification for chart items.
    The hyperlink will be evaluated for every chart item and a image map will be created for the chart.
    
    Specified by:
    
    getItemHyperlink in interface JRHighLowDataset
    
    Returns:
    
    hyperlink specification for chart items
