Method Detail

applyStyles

public void applyStyles(boolean newStyles)
                 throws Exception

Applies styling to the renderer. Internal method.

Overrides:

applyStyles in class IlvChartRenderer

Throws:

Exception

Since:

JViews 5.5

getSingleChild

public IlvChartRenderer getSingleChild(IlvDataSet dataSet)

Returns the child renderer that renders the specified data set.

Since:

JViews 6.5

createChild

protected IlvChartRenderer createChild(IlvDataSet dataSet)

Creates a new child renderer to display the specified data set. This method is called whenever a new data set is connected to this renderer.

Specified by:

createChild in class IlvCompositeChartRenderer

Returns:

A freshly created renderer that is connected to an empty data source. It will be connected to dataSet by the caller.

getType

public static int getType(IlvDataSet dataSet)

Returns the type of the graphical representation of the given data set.

setType

public static void setType(IlvDataSet dataSet,
                           int type)

Sets the type of the graphical representation of the given data set.

Parameters:

dataSet - The data set to represent.

type - The type of the graphical representation.

setAnnotation

public void setAnnotation(IlvDataAnnotation annotation)

Specifies an annotation for all the data points of a data set.

Overrides:

setAnnotation in class IlvChartRenderer

Parameters:

annotation - The new annotation. If this parameter is null, all the global annotations previously defined are removed.

See Also:

IlvChartRenderer.setAnnotation(IlvDataSet, IlvDataAnnotation)

setRenderingHint

public void setRenderingHint(IlvDataRenderingHint hint)

Specifies a global rendering hint for all the data sets displayed by this renderer. The specified hint will also be associated with all the data sets that are connected to this renderer.

Overrides:

setRenderingHint in class IlvChartRenderer

Parameters:

hint - The new rendering hint. If this parameter is null, all the global hints previously defined are removed.

See Also:

IlvCompositeChartRenderer.setRenderingHint(IlvDataSet, IlvDataRenderingHint)

dataSetsRemoved

protected void dataSetsRemoved(int firstIdx,
                               int lastIdx,
                               IlvDataSet[] oldDataSets)

Called when data sets are disconnected from this renderer.

Overrides:

dataSetsRemoved in class IlvChartRenderer

Parameters:

firstIdx - The index of the first data set.

lastIdx - The index of the last data set.

oldDataSets - The data sets previously connected to this renderer.

Since:

JViews 6.5

dataSetsAdded

protected void dataSetsAdded(int firstIdx,
                             int lastIdx,
                             IlvDataSet[] oldDataSets)

Called when data sets are connected to this renderer.

Overrides:

dataSetsAdded in class IlvChartRenderer

Parameters:

firstIdx - The index of the first data set.

lastIdx - The index of the last data set.

oldDataSets - The data sets previously connected to this renderer.

Since:

JViews 6.5

dataSetsChangesBatchStarting

protected void dataSetsChangesBatchStarting()

Called when a series of data sets insertions or removals is starting.

Overrides:

dataSetsChangesBatchStarting in class IlvChartRenderer

Since:

JViews 8.5

See Also:

IlvChartRenderer.dataSetsChangesBatchEnding()

dataSetsChangesBatchEnding

protected void dataSetsChangesBatchEnding()

Called when a series of data sets insertions or removals is terminating.

Overrides:

dataSetsChangesBatchEnding in class IlvChartRenderer

Since:

JViews 8.5

See Also:

IlvChartRenderer.dataSetsChangesBatchStarting()

has3DSupport

public boolean has3DSupport()

Indicates whether this renderer supports three-dimensional drawing.

Specified by:

has3DSupport in interface IlvChart3DSupport

Overrides:

has3DSupport in class IlvChartRenderer

Returns:

true

Since:

JViews 6.5

updateChildren

protected void updateChildren()

Called when children have been added or removed from this renderer. This method lets you carry out a specific operation on the children whenever their number changes.

Overrides:

updateChildren in class IlvCompositeChartRenderer

createLegendItems

public IlvLegendItem[] createLegendItems()

Creates the legend item instances associated to this renderer. This method is automatically called by the legend to populate itself. This implementation differs from the super implementation such that the items are ordered according to the dataset order and not according to the children renderers order.

Overrides:

createLegendItems in class IlvCompositeChartRenderer

Returns:

An array containing all the legend items associated to its child renderers, or null.
