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.

Implements abstract javafx.scene.chart.XYChart.seriesAdded.

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.

protected void updateAxisRange()

Overrides javafx.scene.chart.XYChart.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.
