气泡图

气泡图大小缩放

Aspose.Slides for C++ 支持气泡图大小缩放。在 Aspose.Slides for C++ 中添加了 IChartSeries.BubbleSizeScale 和 IChartSeriesGroup.BubbleSizeScale 属性。下面给出了示例代码。

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/SettingBubbleChartScaling_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::Bubble, 0, 0, 500, 500);

	chart->get_ChartData()->get_SeriesGroups()->idx_get(0)->set_BubbleSizeScale(150);

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

将数据表示为气泡图大小

新的 get_BubbleSizeRepresentation() 方法已添加到 IChartSeries 和 ChartSeries 类中。BubbleSizeRepresentation 指定气泡图中气泡大小值的表示方式。可能的值为：BubbleSizeRepresentationType.Area 和 BubbleSizeRepresentationType.Width。因此，添加了 BubbleSizeRepresentationType 枚举以指定将数据表示为气泡图大小的可能方式。示例代码如下。

	System::SharedPtr<Presentation> pres = System::MakeObject<Presentation>();

	System::SharedPtr<IChart> chart = pres->get_Slides()->idx_get(0)->get_Shapes()->AddChart(Aspose::Slides::Charts::ChartType::Bubble, 50.0f, 50.0f, 600.0f, 400.0f, true);

	chart->get_ChartData()->get_SeriesGroups()->idx_get(0)->set_BubbleSizeRepresentation(Aspose::Slides::Charts::BubbleSizeRepresentationType::Width);

	pres->Save(u"../out/Presentation.pptx", Aspose::Slides::Export::SaveFormat::Pptx);
