Type Parameters:
  `X` - the X axis value type
  `Y` - the Y axis value type

All Implemented Interfaces:
  `Styleable`, `EventTarget`

public class StackedBarChart<X,Y> extends XYChart<X,Y>
StackedBarChart is a variation of `BarChart` that plots bars indicating data values for a category. The bars can be vertical or horizontal depending on which axis is a category axis. The bar for each series is stacked on top of the previous series.

Since:
  JavaFX 2.1

  - ### categoryGapProperty

    public DoubleProperty categoryGapProperty()
    The gap to leave between bars in separate categories
    Returns:
      the `categoryGap` property
    See Also:
      - `getCategoryGap()`
      - `setCategoryGap(double)`

  - ### dataItemAdded

    protected void dataItemAdded(XYChart.Series<X,Y> series, int itemIndex, XYChart.Data<X,Y> item)
    Description copied from class: `XYChart`
    Called when a data item has been added to a series. This is where implementations of XYChart can create/add new nodes to getPlotChildren to represent this data item. They also may animate that data add with a fade in or similar if animated = true.
    Specified by:
      `dataItemAdded` in class `XYChart<X,Y>`
    Parameters:
      `series` - The series the data item was added to
      `itemIndex` - The index of the new item within the series
      `item` - The new data item that was added

  - ### dataItemRemoved

    protected void dataItemRemoved(XYChart.Data<X,Y> item, XYChart.Series<X,Y> series)
    Description copied from class: `XYChart`
    Called when a data item has been removed from data model but it is still visible on the chart. Its still visible so that you can handle animation for removing it in this method. After you are done animating the data item you must call removeDataItemFromDisplay() to remove the items node from being displayed on the chart.
    Specified by:
      `dataItemRemoved` in class `XYChart<X,Y>`
    Parameters:
      `item` - The item that has been removed from the series
      `series` - The series the item was removed from

  - ### dataItemChanged

    protected void dataItemChanged(XYChart.Data<X,Y> item)
    Called when a data item has changed, ie its xValue, yValue or extraValue has changed.
    Specified by:
      `dataItemChanged` in class `XYChart<X,Y>`
    Parameters:
      `item` - The data item who was changed

  - ### seriesAdded

    protected void seriesAdded(XYChart.Series<X,Y> series, int seriesIndex)
    A series has been added to the charts data model. This is where implementations of XYChart can create/add new nodes to getPlotChildren to represent this series. Also you have to handle adding any data items that are already in the series. You may simply call dataItemAdded() for each one or provide some different animation for a whole series being added.
    Specified by:
      `seriesAdded` in class `XYChart<X,Y>`
    Parameters:
      `series` - The series that has been added
      `seriesIndex` - The index of the new series

  - ### seriesRemoved

    protected void seriesRemoved(XYChart.Series<X,Y> series)
    Description copied from class: `XYChart`
    A series has been removed from the data model but it is still visible on the chart. Its still visible so that you can handle animation for removing it in this method. After you are done animating the data item you must call removeSeriesFromDisplay() to remove the series from the display list.
    Specified by:
      `seriesRemoved` in class `XYChart<X,Y>`
    Parameters:
      `series` - The series that has been removed

  - ### layoutPlotChildren

    protected void layoutPlotChildren()
    Called to update and layout the plot children. This should include all work to updates nodes representing the plot on top of the axis and grid lines etc. The origin is the top left of the plot area, the plot area with can be got by getting the width of the x axis and its height from the height of the y axis.
    Specified by:
      `layoutPlotChildren` in class `XYChart<X,Y>`

  - ### getClassCssMetaData

    public static List<CssMetaData<? extends Styleable, ?>> getClassCssMetaData()
    Gets the `CssMetaData` associated with this class, which may include the `CssMetaData` of its superclasses.
    Returns:
      the `CssMetaData`
    Since:
      JavaFX 8.0

  - ### getCssMetaData

    public List<CssMetaData<? extends Styleable, ?>> getCssMetaData()
    This method should delegate to `Node.getClassCssMetaData()` so that a Node's CssMetaData can be accessed without the need for reflection.
    Specified by:
      `getCssMetaData` in interface `Styleable`
    Overrides:
      `getCssMetaData` in class `XYChart<X,Y>`
    Returns:
      The CssMetaData associated with this node, which may include the CssMetaData of its superclasses.
    Since:
      JavaFX 8.0
