Implements abstract javafx.scene.chart.XYChart.dataItemAdded.

Doc from javafx.scene.chart.XYChart.dataItemAdded.

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.

Implements abstract javafx.scene.chart.XYChart.dataItemRemoved.

Doc from javafx.scene.chart.XYChart.dataItemRemoved.

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.

protected void layoutPlotChildren()

Implements abstract javafx.scene.chart.XYChart.layoutPlotChildren.

Doc from javafx.scene.chart.XYChart.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.

Doc from javafx.scene.chart.XYChart.seriesAdded.

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.
