# Class XYChart<X,​Y>

java.lang.Object
javafx.scene.Node
javafx.scene.Parent
javafx.scene.layout.Region
javafx.scene.chart.Chart
javafx.scene.chart.XYChart<X,​Y>

All Implemented Interfaces:
  `Styleable`, `EventTarget`

Direct Known Subclasses:
  `AreaChart`, `BarChart`, `BubbleChart`, `LineChart`, `ScatterChart`, `StackedAreaChart`, `StackedBarChart`

    public abstract class XYChart<X,​Y>
    extends Chart

Chart base class for all 2 axis charts. It is responsible for drawing the two axes and the plot content. It contains a list of all content in the plot and implementations of XYChart can add nodes to this list that need to be rendered.

It is possible to install Tooltips on data items / symbols. For example the following code snippet installs Tooltip on the 1st data item.

      XYChart.Data item = ( XYChart.Data)series.getData().get(0);
      Tooltip.install(item.getNode(), new Tooltip("Symbol-0"));

Since:
  JavaFX 2.0

  - ### updateLegend

    protected void updateLegend()
    This is called whenever a series is added or removed and the legend needs to be updated

  - ### dataItemAdded

    protected abstract void dataItemAdded​(XYChart.Series<X,​Y> series, int itemIndex, XYChart.Data<X,​Y> item)
    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.
    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

After you are done animating the data item you must call removeDataItemFromDisplay() to remove the items node from being displayed on the chart.
    Parameters:
      `item` - The item that has been removed from the series
      `series` - The series the item was removed from

  - ### dataItemChanged

    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.
    Parameters:
      `series` - The series that has been added
      `seriesIndex` - The index of the new series

  - ### seriesRemoved

  - ### seriesChanged

    protected void seriesChanged​(ListChangeListener.Change<? extends XYChart.Series> c)
    Called when each atomic change is made to the list of series for this chart
    Parameters:
      `c` - a Change instance representing the changes to the series

  - ### updateAxisRange

    protected void updateAxisRange()
    This is called when the range has been invalidated and we need to update it. If the axis are auto ranging then we compile a list of all data that the given axis has to plot and call invalidateRange() on the axis passing it that data.

  - ### layoutPlotChildren

    protected abstract 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.

  - ### layoutChartChildren

    protected final void layoutChartChildren​(double top, double left, double width, double height)
    Called to update and layout the chart children available from getChartChildren()
    Specified by:
      `layoutChartChildren` in class `Chart`
    Parameters:
      `top` - The top offset from the origin to account for any padding on the chart content
      `left` - The left offset from the origin to account for any padding on the chart content
      `width` - The width of the area to layout the chart within
      `height` - The height of the area to layout the chart within

  - ### removeSeriesFromDisplay

    protected final void removeSeriesFromDisplay​(XYChart.Series<X,​Y> series)
    This should be called from seriesRemoved() when you are finished with any animation for deleting the series from the chart. It will remove the series from showing up in the Iterator returned by getDisplayedSeriesIterator().
    Parameters:
      `series` - The series to remove

  - ### getDisplayedSeriesIterator

    protected final Iterator<XYChart.Series<X,​Y>> getDisplayedSeriesIterator()
    XYChart maintains a list of all series currently displayed this includes all current series + any series that have recently been deleted that are in the process of being faded(animated) out. This creates and returns a iterator over that list. This is what implementations of XYChart should use when plotting data.
    Returns:
      iterator over currently displayed series

  - ### getCurrentDisplayedXValue

    protected final X getCurrentDisplayedXValue​(XYChart.Data<X,​Y> item)
    The current displayed data value plotted on the X axis. This may be the same as xValue or different. It is used by XYChart to animate the xValue from the old value to the new value. This is what you should plot in any custom XYChart implementations. Some XYChart chart implementations such as LineChart also use this to animate when data is added or removed.
    Parameters:
      `item` - The XYChart.Data item from which the current X axis data value is obtained
    Returns:
      The current displayed X data value

      `getCurrentDisplayedXValue(Data)`

  - ### getCurrentDisplayedYValue

    protected final Y getCurrentDisplayedYValue​(XYChart.Data<X,​Y> item)
    The current displayed data value plotted on the Y axis. This may be the same as yValue or different. It is used by XYChart to animate the yValue from the old value to the new value. This is what you should plot in any custom XYChart implementations. Some XYChart chart implementations such as LineChart also use this to animate when data is added or removed.
    Parameters:
      `item` - The XYChart.Data item from which the current Y axis data value is obtained
    Returns:
      The current displayed Y data value

  - ### setCurrentDisplayedYValue

    protected final void setCurrentDisplayedYValue​(XYChart.Data<X,​Y> item, Y value)
    Set the current displayed data value plotted on Y axis.
