- Method Detail
  - 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.
  - setSeriesExpression
```
public void setSeriesExpression(JRExpression seriesExpression)
```
  - 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.
  - setDateExpression
```
public void setDateExpression(JRExpression dateExpression)
```
  - 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.
  - setHighExpression
```
public void setHighExpression(JRExpression highExpression)
```
  - 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.
  - setLowExpression
```
public void setLowExpression(JRExpression lowExpression)
```
  - getOpenExpression
```
public JRExpression 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.
  - setOpenExpression
```
public void setOpenExpression(JRExpression openExpression)
```
  - 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.
  - setCloseExpression
```
public void setCloseExpression(JRExpression closeExpression)
```
  - 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.
  - setVolumeExpression
```
public void setVolumeExpression(JRExpression volumeExpression)
```
  - 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.
    
    Specified by:
    
    getDatasetType in interface JRChartDataset
    
    Overrides:
    
    getDatasetType in class JRDesignChartDataset

```
public void collectExpressions(JRExpressionCollector collector)
```
    Specified by:
    
    collectExpressions in interface JRElementDataset
    
    Overrides:
    
    collectExpressions in class JRBaseElementDataset
  - 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
  - setItemHyperlink
```
public void setItemHyperlink(JRHyperlink itemHyperlink)
```
    Sets the hyperlink specification for chart items.
    
    Parameters:
    itemHyperlink - the hyperlink specification
    See Also:
    getItemHyperlink()
  - validate
```
public void validate(JRVerifier verifier)
```
    Description copied from interface: JRChartDataset
    
    Validates the dataset using a verifier.
    Broken rules are collected by the verifier.
    
    Specified by:
    
    validate in interface JRChartDataset
    
    Parameters:
    verifier - the verifier to use for validation
  - clone
```
public Object clone()
```
    Specified by:
    
    clone in interface JRCloneable
    
    Overrides:
