DataLabelCollection

public interface IDataLabelCollection
extends com.aspose.ms.System.Collections.Generic.IGenericEnumerable<IDataLabel>, IChartComponent

Represents a series labels.

Method Summary

Modifier and Type	Method and Description
IDataLabel	get_Item(int index) Gets the data label for the data point with the specified index.
int	getCount() Gets the number of all data labels in the collection.
int	getCountOfVisibleDataLabels() Gets the number of visible data labels in the collection.
IDataLabelFormat	getDefaultDataLabelFormat() Returns default format of all data labels in the collection.
IChartLinesFormat	getLeaderLinesFormat() Represents data labels leader lines format.
IChartSeries	getParentSeries() Returns parent chart series.
void	hide() Make data label hidden by default by setting all Show*-flags (ShowValue, ...) of the DefaultDataLabelFormat property to false state.
int	indexOf(IDataLabel value) Returns an index of the specified DataLabel in the collection.
boolean	isVisible() False means that data label is not visible by default (and so all Show*-flags (ShowValue, ...) of the DefaultDataLabelFormat property are false).

Method Detail

get_Item

IDataLabel get_Item(int index)

Gets the data label for the data point with the specified index.

Alternate way to access data label is: - getSeries().getDataPoints().get_Item(i).getLabel() - manage label properties.

getDefaultDataLabelFormat

IDataLabelFormat getDefaultDataLabelFormat()

Returns default format of all data labels in the collection. Read-only IDataLabelFormat.

getLeaderLinesFormat

IChartLinesFormat getLeaderLinesFormat()

Represents data labels leader lines format. Read-only IChartLinesFormat.

Example:
  
 Presentation pres = new Presentation("pres.pptx");
 try {
     IChart chart = (IChart) pres.getSlides().get_Item(0).getShapes().get_Item(0);
     IChartSeriesCollection series = chart.getChartData().getSeries();
     IDataLabelCollection labels = series.get_Item(0).getLabels();
     labels.getLeaderLinesFormat().getLine().getFillFormat().setFillType(FillType.Solid);
     labels.getLeaderLinesFormat().getLine().getFillFormat().getSolidFillColor().setColor(new java.awt.Color(255, 0, 0, 255));
 } finally {
     if (pres != null) pres.dispose();
 }
  
  

isVisible

boolean isVisible()

False means that data label is not visible by default (and so all Show*-flags (ShowValue, ...) of the DefaultDataLabelFormat property are false). Read-only boolean.

If data label is visible by default you can make it hidden by default with Hide() method. But if data label is not visible by default (IsVisible is false) you can make data label "visible by default" with setting Show*-flags (ShowValue, ...) of the DefaultDataLabelFormat property to true state.

hide

void hide()

Make data label hidden by default by setting all Show*-flags (ShowValue, ...) of the DefaultDataLabelFormat property to false state. IsVisible will be false after this.

If data label is not visible by default (IsVisible is false) you can make data label "visible by default" with setting Show*-flags (ShowValue, ...) of the DefaultDataLabelFormat property to true state.

getCountOfVisibleDataLabels

int getCountOfVisibleDataLabels()

Gets the number of visible data labels in the collection. Read-only int.

getCount

int getCount()

Gets the number of all data labels in the collection. Read-only int.

getParentSeries

IChartSeries getParentSeries()

Returns parent chart series. Read-only IChartSeries.

indexOf

int indexOf(IDataLabel value)

Returns an index of the specified DataLabel in the collection.

Parameters:

value - DataLabel to find.

Returns:

Index of a DataLabel or -1 if DataLabel not from this collection.
