Property Detail

createSymbols

public final BooleanProperty createSymbolsProperty

When true, CSS styleable symbols are created for any data items that don't have a symbol node specified.

See Also:

setCreateSymbols(boolean)

Constructor Detail

LineChart

public LineChart(Axis<X> xAxis,
         Axis<Y> yAxis)

Construct a new LineChart with the given axis.

Parameters:

xAxis - The x axis to use

yAxis - The y axis to use

LineChart

public LineChart(Axis<X> xAxis,
         Axis<Y> yAxis,
         ObservableList<XYChart.Series<X,Y>> data)

Construct a new LineChart with the given axis and data.

Parameters:

xAxis - The x axis to use

yAxis - The y axis to use

data - The data to use, this is the actual list used so any changes to it will be reflected in the chart

Method Detail

getCreateSymbols

public final boolean getCreateSymbols()

Indicates whether symbols for data points will be created or not.

Returns:

true if symbols for data points will be created and false otherwise.

setCreateSymbols

public final void setCreateSymbols(boolean value)

Sets the value of the property createSymbols.

Property description:

When true, CSS styleable symbols are created for any data items that don't have a symbol node specified.

createSymbolsProperty

public final BooleanProperty createSymbolsProperty()

When true, CSS styleable symbols are created for any data items that don't have a symbol node specified.

See Also:

setCreateSymbols(boolean)

dataItemAdded

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

Description copied from class: XYChart

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>

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 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)

Description copied from class: XYChart

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

seriesChanged

protected void seriesChanged(ListChangeListener.Change<? extends XYChart.Series> c)

Description copied from class: XYChart

Called when each atomic change is made to the list of series for this chart

Overrides:

seriesChanged in class XYChart<X,Y>

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()

Description copied from class: XYChart

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.

Specified by:

layoutPlotChildren in class XYChart<X,Y>

updateLegend

protected void updateLegend()

This is called whenever a series is added or removed and the legend needs to be updated

Overrides:

updateLegend in class XYChart<X,Y>
