Bubble Chart

Bubble Chart Size Scaling

Aspose.Slides for C++ provides support for Bubble chart size scaling. In Aspose.Slides for C++ IChartSeries.BubbleSizeScale and IChartSeriesGroup.BubbleSizeScale properties have been added. Below sample example is given.

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);

Represent Data as Bubble Chart Sizes

New get_BubbleSizeRepresentation() method has been added to IChartSeries and ChartSeries classes. BubbleSizeRepresentation specifies how the bubble size values are represented in the bubble chart. Possible values are: BubbleSizeRepresentationType.Area and BubbleSizeRepresentationType.Width. Accordingly, BubbleSizeRepresentationType enum has been added to specify the possible ways to represent data as bubble chart sizes. Sample code is given below.

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);
