3D 图表

设置 3D 图表的 RotationX、RotationY 和 DepthPercents 属性

Aspose.Slides for C++ 提供了一个简单的 API 来设置这些属性。以下文章将帮助您设置不同的属性，如 X、Y 旋转，DepthPercents 等。示例代码应用了上述属性的设置。

1. 创建一个 Presentation 类的实例。
2. 访问第一张幻灯片。
3. 添加带有默认数据的图表。
4. 设置 Rotation3D 属性。
5. 将修改后的演示文稿写入 PPTX 文件。

	// 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);
