    This method is not supported by this renderer, because it is associated with the entire data source, not with a single data set.
    
    Specified by:
    
    setAnnotation in class IlvChartRenderer
    
    Parameters:
    
    dataSet - The considered data set.
    
    annotation - The new annotation, or null if the global annotation must be removed.
    
    Throws:
    
    UnsupportedOperationException

public IlvDataAnnotation getAnnotation(IlvDataSet dataSet,
                                       int idx)
```
    This method always returns null, because this renderer is associated with the entire data source, not with a single data set.
    
    Specified by:
    
    getAnnotation in class IlvChartRenderer
    
    Parameters:
    
    dataSet - The considered data set.
    
    idx - The index of the point within the data set.
    
    Returns:
    
    The annotation associated with the data point.

                             IlvDataRenderingHint hint)
```
    This method is not supported by this renderer, because it is associated with the entire data source, not with a single data set.
    
    Specified by:
    
    setRenderingHint in class IlvChartRenderer
    
    Parameters:
    
    dataSet - The considered data set.
    
    idx - The index of the considered point in the data set.
    
    hint - The new rendering hint, or null if the hint associated with the specified point must be removed. If an hint has already been specified globally with the IlvChartRenderer.setRenderingHint(IlvDataSet, IlvDataRenderingHint)} method, it is overridden by this new hint. In that case, a null value has no effect.
    
    Throws:
    
    UnsupportedOperationException

  - computeDataLabel
```
public String computeDataLabel(IlvDataSetPoint dp)
```
    Computes the data label associated with the specified object.
    This method is used for data labeling. The returned string depends on the column specified through the setLabelColumnName(java.lang.String) method.
    
    Overrides:
    
    computeDataLabel in class IlvChartRenderer
    
    Parameters:
    
    dp - An instance of IlvDisplayObjectArea.
    
    Returns:
    
    The string corresponding to the specified data object, or null if no label is available.
  - computeDataLabelLocation
```
public Point computeDataLabelLocation(IlvDisplayPoint dp,
                                      Dimension size)
```
    Computes the location of the data label associated with the specified object.
    
    Overrides:
    
    computeDataLabelLocation in class IlvChartRenderer
    
    Parameters:
    
    dp - An instance of IlvDisplayObjectArea.
    
    size - The size of the label.
    
    Returns:
    
    The location of the center of the label.

  - computeInfoTextDescriptionPart
```
public String computeInfoTextDescriptionPart(IlvDisplayObjectArea da)
```
    Computes the part of the tooltip that describes an object.
    This method is used by the default implementation of getInfoTextDescriptionPart in IlvChartInfoViewInteractor.
    
    See Also:
    
    IlvChartInfoViewInteractor, IlvChartInfoViewInteractor.getInfoTextDescriptionPart(ilog.views.chart.IlvDisplayPoint)
  - computeInfoTextValuePart
```
public String computeInfoTextValuePart(IlvDisplayObjectArea da)
```
    Computes the part of the tooltip that describes the value for an object.
    This method is used by the default implementation of getInfoTextValuePart in IlvChartInfoViewInteractor.
    This method uses the value from the color column (see setColorColumn(ilog.views.chart.datax.IlvDataColumnInfo)) and formats it to a string (see setLegendLabelFormat(java.text.Format)).

  - applyStyles
```
public void applyStyles(boolean newStyles)
                 throws Exception
```
    Applies styling to the renderer. Internal method.

  - applyStyles
```
public ilog.views.chart.styling.IlvDataModelStyle applyStyles(ilog.views.chart.styling.IlvStylingSupport support)
```
    Applies styles on the specified data model. Internal method.
    
    Parameters:
    
    support - CSS manager.
    
    Returns:
    
    An IlvDataModelStyle that holds the styling information on the data model.
