Detailed Description

Represents a series labels.

Member Function Documentation

◆ get_Count()

virtual int32_t Aspose::Slides::Charts::IDataLabelCollection::get_Count ( )
pure virtual

Gets the number of all data labels in the collection. Read-only int32_t.

Implemented in Aspose::Slides::Charts::DataLabelCollection.

◆ get_CountOfVisibleDataLabels()

virtual int32_t Aspose::Slides::Charts::IDataLabelCollection::get_CountOfVisibleDataLabels ( )
pure virtual

Gets the number of visible data labels in the collection. Read-only int32_t.

Implemented in Aspose::Slides::Charts::DataLabelCollection.

◆ get_DefaultDataLabelFormat()

virtual System::SharedPtr<IDataLabelFormat> Aspose::Slides::Charts::IDataLabelCollection::get_DefaultDataLabelFormat ( )
pure virtual

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

Implemented in Aspose::Slides::Charts::DataLabelCollection.

◆ get_IsVisible()

virtual bool Aspose::Slides::Charts::IDataLabelCollection::get_IsVisible ( )
pure virtual

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

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.

Implemented in Aspose::Slides::Charts::DataLabelCollection.

◆ get_ParentSeries()

virtual System::SharedPtr<IChartSeries> Aspose::Slides::Charts::IDataLabelCollection::get_ParentSeries ( )
pure virtual

Returns parent chart series. Read-only IChartSeries.

Implemented in Aspose::Slides::Charts::DataLabelCollection.

◆ Hide()

virtual void Aspose::Slides::Charts::IDataLabelCollection::Hide ( )
pure virtual

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.

Implemented in Aspose::Slides::Charts::DataLabelCollection.

◆ idx_get()

virtual System::SharedPtr<IDataLabel> Aspose::Slides::Charts::IDataLabelCollection::idx_get ( int32_t  index)
pure virtual

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

Alternate way to access data label is:

  • SeriesEx.DataPoints[i].Label - manage label properties.

Implemented in Aspose::Slides::Charts::DataLabelCollection.

◆ IndexOf()

virtual int32_t Aspose::Slides::Charts::IDataLabelCollection::IndexOf ( System::SharedPtr< IDataLabel value)
pure virtual

Returns an index of the specified DataLabel in the collection.

Parameters
valueDataLabel to find.
Returns
Index of a DataLabel or -1 if DataLabel not from this collection.

Implemented in Aspose::Slides::Charts::DataLabelCollection.
