Class StackedXYBarRenderer

    java.lang.Object
      org.jfree.chart.renderer.AbstractRenderer
          org.jfree.chart.renderer.xy.AbstractXYItemRenderer
              org.jfree.chart.renderer.xy.XYBarRenderer
                  org.jfree.chart.renderer.xy.StackedXYBarRenderer

All Implemented Interfaces:
  java.io.Serializable, java.lang.Cloneable, LegendItemSource, XYItemRenderer, org.jfree.util.PublicCloneable

    public class StackedXYBarRenderer

extends XYBarRenderer

A bar renderer that displays the series items stacked. The dataset used together with this renderer must be a `IntervalXYDataset` and a `TableXYDataset`. For example, the dataset class `CategoryTableXYDataset` implements both interfaces.

Constructor Summary
`StackedXYBarRenderer()` Creates a new renderer.
`StackedXYBarRenderer(double margin)` Creates a new renderer.

Method Summary
`void` | `drawItem(java.awt.Graphics2D g2, XYItemRendererState state, java.awt.geom.Rectangle2D dataArea, PlotRenderingInfo info, XYPlot plot, ValueAxis domainAxis, ValueAxis rangeAxis, XYDataset dataset, int series, int item, CrosshairState crosshairState, int pass)` Draws the visual representation of a single data item.
`boolean` | `equals(java.lang.Object obj)` Tests this renderer for equality with an arbitrary object.
`Range` | `findRangeBounds(XYDataset dataset)` Returns the range of values the renderer requires to display all the items from the specified dataset.
`int` | `getPassCount()` Returns `2` to indicate that this renderer requires two passes for drawing (item labels are drawn in the second pass so that they always appear in front of all the bars).
`boolean` | `getRenderAsPercentages()` Returns `true` if the renderer displays each item value as a percentage (so that the stacked bars add to 100%), and `false` otherwise.
`int` | `hashCode()` Returns a hash code for this instance.
`XYItemRendererState` | `initialise(java.awt.Graphics2D g2, java.awt.geom.Rectangle2D dataArea, XYPlot plot, XYDataset data, PlotRenderingInfo info)` Initialises the renderer and returns a state object that should be passed to all subsequent calls to the drawItem() method.
`void` | `setRenderAsPercentages(boolean asPercentages)` Sets the flag that controls whether the renderer displays each item value as a percentage (so that the stacked bars add to 100%), and sends a `RendererChangeEvent` to all registered listeners.

### StackedXYBarRenderer

    public StackedXYBarRenderer()

  Creates a new renderer.

### StackedXYBarRenderer

    public StackedXYBarRenderer(double margin)

  Creates a new renderer.

  Parameters:
    `margin` - the percentual amount of the bars that are cut away.

Method Detail

### getRenderAsPercentages

    public boolean getRenderAsPercentages()

  Returns `true` if the renderer displays each item value as a percentage (so that the stacked bars add to 100%), and `false` otherwise.

  Returns:
    A boolean.
  Since:
    1.0.5

    `setRenderAsPercentages(boolean)`

### setRenderAsPercentages

    public void setRenderAsPercentages(boolean asPercentages)

  Sets the flag that controls whether the renderer displays each item value as a percentage (so that the stacked bars add to 100%), and sends a `RendererChangeEvent` to all registered listeners.

  Parameters:
    `asPercentages` - the flag.
  Since:
    1.0.5
  See Also:
    `getRenderAsPercentages()`

### getPassCount

    public int getPassCount()
