Aspose::Words::Drawing::Charts::Chart::get_Series method

Chart::get_Series method

Provides access to series collection.

System::SharedPtr<Aspose::Words::Drawing::Charts::ChartSeriesCollection> Aspose::Words::Drawing::Charts::Chart::get_Series()

Examples

Shows how to create an appropriate type of chart series for a graph type.
