    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>`

      `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)
    Description copied from class: `XYChart`
    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()

    Specified by:
      `getCssMetaData` in interface `Styleable`
    Overrides:
      `getCssMetaData` in class `XYChart<X,Y>`
