getPlotChildren

protected ObservableList<Node> getPlotChildren()

Modifiable and observable list of all content in the plot. This is where implementations of XYChart should add any nodes they use to draw their plot.

Returns:

Observable list of plot children

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

dataItemRemoved

protected abstract void dataItemRemoved(XYChart.Data<X,Y> item,
                   XYChart.Series<X,Y> series)

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.

Parameters:

item - The item that has been removed from the series

series - The series the item was removed from

dataItemChanged

protected abstract void dataItemChanged(XYChart.Data<X,Y> item)

Called when a data item has changed, ie its xValue, yValue or extraValue has changed.

Parameters:

item - The data item who was changed

seriesAdded

protected abstract 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.

Parameters:

series - The series that has been added

seriesIndex - The index of the new series

seriesRemoved

protected abstract void seriesRemoved(XYChart.Series<X,Y> series)

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.

Parameters:

series - The series that has been removed

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

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)

Description copied from class: Chart

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 java.util.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.

setCurrentDisplayedXValue

protected final void setCurrentDisplayedXValue(XYChart.Data<X,Y> item,
                             X value)

Set the current displayed data value plotted on X axis.

Parameters:

item - The XYChart.Data item from which the current X axis data value is obtained.

See Also:

getCurrentDisplayedXValue(javafx.scene.chart.XYChart.Data)

currentDisplayedXValueProperty

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.

setCurrentDisplayedYValue

protected final void setCurrentDisplayedYValue(XYChart.Data<X,Y> item,
                             Y value)
