    Draws the visual representation of a single data item.
    
    Specified by:
    
    drawItem in interface XYItemRenderer
    
    Parameters:
    
    g2 - the graphics device.
    
    state - the renderer state.
    
    dataArea - the area within which the plot is being drawn.
    
    info - collects information about the drawing.
    
    plot - the plot (can be used to obtain standard color information etc).
    
    domainAxis - the domain axis.
    
    rangeAxis - the range axis.
    
    dataset - the dataset.
    
    series - the series index (zero-based).
    
    item - the item index (zero-based).
    
    crosshairState - crosshair information for the plot (null permitted).
    
    pass - the pass index.
  - drawItemLabel
```
protected void drawItemLabel(java.awt.Graphics2D g2,
                             XYDataset dataset,
                             int series,
                             int item,
                             XYPlot plot,
                             XYItemLabelGenerator generator,
                             java.awt.geom.Rectangle2D bar,
                             boolean negative)
```
    Draws an item label. This method is provided as an alternative to AbstractXYItemRenderer.drawItemLabel(Graphics2D, PlotOrientation, XYDataset, int, int, double, double, boolean) so that the bar can be used to calculate the label anchor point.
    
    Parameters:
    
    g2 - the graphics device.
    
    dataset - the dataset.
    
    series - the series index.
    
    item - the item index.
    
    plot - the plot.
    
    generator - the label generator (null permitted, in which case the method does nothing, just returns).
    
    bar - the bar.
    
    negative - a flag indicating a negative value.
  - findDomainBounds
```
public Range findDomainBounds(XYDataset dataset)
```
    Returns the lower and upper bounds (range) of the x-values in the specified dataset. Since this renderer uses the x-interval in the dataset, this is taken into account for the range.
    
    Specified by:
    
    findDomainBounds in interface XYItemRenderer
    
    Overrides:
    
    findDomainBounds in class AbstractXYItemRenderer
    
    Parameters:
    
    dataset - the dataset (null permitted).
    
    Returns:
    
    The range (null if the dataset is null or empty).
    
    See Also:
    
    AbstractXYItemRenderer.findRangeBounds(XYDataset)
  - findRangeBounds
```
public Range findRangeBounds(XYDataset dataset)
```
    Returns the lower and upper bounds (range) of the y-values in the specified dataset. If the renderer is plotting the y-interval from the dataset, this is taken into account for the range.
    
    Specified by:
    
    findRangeBounds in interface XYItemRenderer
    
    Overrides:
    
    findRangeBounds in class AbstractXYItemRenderer
    
    Parameters:
    
    dataset - the dataset (null permitted).
    
    Returns:
    
    The range (null if the dataset is null or empty).
    
    See Also:
    
    AbstractXYItemRenderer.findDomainBounds(XYDataset)
  - clone
```
public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException
```
    Returns a clone of the renderer.
    
    Specified by:
    
    clone in interface org.jfree.util.PublicCloneable
    
    Overrides:
    
    clone in class AbstractXYItemRenderer
    
    Returns:
    
    A clone.
    
    Throws:
    
    java.lang.CloneNotSupportedException - if the renderer cannot be cloned.
  - equals
```
public boolean equals(java.lang.Object obj)
```
    Tests this renderer for equality with an arbitrary object.
    
    Overrides:
    
    equals in class AbstractXYItemRenderer
    
    Parameters:
    
    obj - the object to test against (null permitted).
    
    Returns:
    
    A boolean.
