3D Chart

Set RotationX, RotationY and DepthPercents properties of 3D Chart

Aspose.Slides for C++ provides a simple API for setting these properties. This following article will help you how set different properties like X,Y Rotation , DepthPercents etc. The sample code applies setting the above said properties.

1. Create an instance of the Presentation class.
2. Access first slide.
3. Add chart with default data.
4. Set Rotation3D properties.
5. Write the modified presentation to a PPTX file.

For complete examples and data files, please go to https://github.com/aspose-slides/Aspose.Slides-for-C

	// The path to the documents directory.
	const String outPath = u"../out/ManagePropertiesCharts_out.pptx";

	//Instantiate Presentation class that represents PPTX file
	SharedPtr<Presentation> pres = MakeObject<Presentation>();

	//Access first slide
	SharedPtr<ISlide> slide = pres->get_Slides()->idx_get(0);

	// Add chart with default data
	SharedPtr<IChart> chart = slide->get_Shapes()->AddChart(Aspose::Slides::Charts::ChartType::StackedColumn3D, 0, 0, 500, 500);


	// Setting the index of chart data sheet
	int defaultWorksheetIndex = 0;

	// Getting the chart data worksheet
	SharedPtr<IChartDataWorkbook> fact = chart->get_ChartData()->get_ChartDataWorkbook();

	// Now, Adding a new series
	chart->get_ChartData()->get_Series()->Add(fact->GetCell(defaultWorksheetIndex, 0, 1, ObjectExt::Box<System::String>(u"Series 1")), chart->get_Type());
	chart->get_ChartData()->get_Series()->Add(fact->GetCell(defaultWorksheetIndex, 0, 2, ObjectExt::Box<System::String>(u"Series 2")), chart->get_Type());

	// Add Catrgories
	chart->get_ChartData()->get_Categories()->Add(fact->GetCell(defaultWorksheetIndex, 1, 0, ObjectExt::Box<System::String>(u"Caetegoty 1")));
	chart->get_ChartData()->get_Categories()->Add(fact->GetCell(defaultWorksheetIndex, 2, 0, ObjectExt::Box<System::String>(u"Caetegoty 2")));
	chart->get_ChartData()->get_Categories()->Add(fact->GetCell(defaultWorksheetIndex, 3, 0, ObjectExt::Box<System::String>(u"Caetegoty 3")));
	
	// Set Rotation3D properties
	chart->get_Rotation3D()->set_RightAngleAxes(true);
	chart->get_Rotation3D()->set_RotationX ( 40);
	chart->get_Rotation3D()->set_RotationY ( 270);
	chart->get_Rotation3D()->set_DepthPercents ( 150);

	// Take second chart series
	SharedPtr<IChartSeries> series = chart->get_ChartData()->get_Series()->idx_get(1);

	// Now populating series data
	series->get_DataPoints()->AddDataPointForBarSeries(fact->GetCell(defaultWorksheetIndex, 1, 1, ObjectExt::Box<double>(20)));
	series->get_DataPoints()->AddDataPointForBarSeries(fact->GetCell(defaultWorksheetIndex, 2, 1, ObjectExt::Box<double>(50)));
	series->get_DataPoints()->AddDataPointForBarSeries(fact->GetCell(defaultWorksheetIndex, 3, 1, ObjectExt::Box<double>(30)));
	series->get_DataPoints()->AddDataPointForBarSeries(fact->GetCell(defaultWorksheetIndex, 1, 2, ObjectExt::Box<double>(30)));
	series->get_DataPoints()->AddDataPointForBarSeries(fact->GetCell(defaultWorksheetIndex, 2, 2, ObjectExt::Box<double>(10)));
	series->get_DataPoints()->AddDataPointForBarSeries(fact->GetCell(defaultWorksheetIndex, 3, 2, ObjectExt::Box<double>(60)));

	// Set OverLap value
	series->get_ParentSeriesGroup()->set_Overlap ( 100);


	// Write the presentation file to disk
	pres->Save(outPath, Aspose::Slides::Export::SaveFormat::Pptx);
