图表是简洁显示数据的绝佳工具。此外,它们通过直观地表示,使使用大量数据变得更加容易。在演示诸如公司的增长趋势或产品采用率之类的数据时,向演示文稿中添加图表可能会有所帮助。为此,本文将教您如何 使用C ++在PowerPoint演示文稿中创建图表。
Aspose.Slides for C ++ 是本机C ++库,支持创建,读取和操作PowerPoint文件。该API还支持在PowerPoint演示文稿中创建图表。您可以点击下方按钮下载体验。
以下是在PowerPoint演示文稿中创建柱形图的步骤。
以下是使用C ++在PowerPoint Presentation中添加柱形图的示例代码。
// Output File Path. const String outputFilePath = u"OutputDirectory\\column_chart.pptx"; // Instantiate Presentation class that represents PPTX file SharedPtrpres = MakeObject(); // Access first slide SharedPtrslide = pres->get_Slides()->idx_get(0); // Add chart with default data SharedPtrchart = slide->get_Shapes()->AddChart(Aspose::Slides::Charts::ChartType::ClusteredColumn, 0, 0, 500, 500); // Setting the index of chart data sheet int defaultWorksheetIndex = 0; // Getting the chart data workbook SharedPtrfact = chart->get_ChartData()->get_ChartDataWorkbook(); // Setting chart Title chart->get_ChartTitle()->AddTextFrameForOverriding(u"Sample Title"); chart->get_ChartTitle()->get_TextFrameForOverriding()->get_TextFrameFormat()->set_CenterText(NullableBool::True); chart->get_ChartTitle()->set_Height(20); chart->set_HasTitle(true); // Delete default generated series and categories chart->get_ChartData()->get_Series()->Clear(); chart->get_ChartData()->get_Categories()->Clear(); int s = chart->get_ChartData()->get_Series()->get_Count(); s = chart->get_ChartData()->get_Categories()->get_Count(); // Add series chart->get_ChartData()->get_Series()->Add(fact->GetCell(defaultWorksheetIndex, 0, 1, ObjectExt::Box(u"Series 1")), chart->get_Type()); chart->get_ChartData()->get_Series()->Add(fact->GetCell(defaultWorksheetIndex, 0, 2, ObjectExt::Box(u"Series 2")), chart->get_Type()); // Add categories chart->get_ChartData()->get_Categories()->Add(fact->GetCell(defaultWorksheetIndex, 1, 0, ObjectExt::Box(u"Category 1"))); chart->get_ChartData()->get_Categories()->Add(fact->GetCell(defaultWorksheetIndex, 2, 0, ObjectExt::Box(u"Category 2"))); chart->get_ChartData()->get_Categories()->Add(fact->GetCell(defaultWorksheetIndex, 3, 0, ObjectExt::Box(u"Category 3"))); // Take first chart series SharedPtrseries = chart->get_ChartData()->get_Series()->idx_get(0); // Populate series data series->get_DataPoints()->AddDataPointForBarSeries(fact->GetCell(defaultWorksheetIndex, 1, 1, ObjectExt::Box(20))); series->get_DataPoints()->AddDataPointForBarSeries(fact->GetCell(defaultWorksheetIndex, 2, 1, ObjectExt::Box(50))); series->get_DataPoints()->AddDataPointForBarSeries(fact->GetCell(defaultWorksheetIndex, 3, 1, ObjectExt::Box(30))); // Setting fill color for series series->get_Format()->get_Fill()->set_FillType(FillType::Solid); series->get_Format()->get_Fill()->get_SolidFillColor()->set_Color(System::Drawing::Color::get_Blue()); // Take second chart series series = chart->get_ChartData()->get_Series()->idx_get(1); // Populate series data series->get_DataPoints()->AddDataPointForBarSeries(fact->GetCell(defaultWorksheetIndex, 1, 2, ObjectExt::Box(30))); series->get_DataPoints()->AddDataPointForBarSeries(fact->GetCell(defaultWorksheetIndex, 2, 2, ObjectExt::Box(10))); series->get_DataPoints()->AddDataPointForBarSeries(fact->GetCell(defaultWorksheetIndex, 3, 2, ObjectExt::Box(60))); // Setting fill color for series series->get_Format()->get_Fill()->set_FillType(FillType::Solid); series->get_Format()->get_Fill()->get_SolidFillColor()->set_Color(System::Drawing::Color::get_Orange()); // First label will be show Category name SharedPtrlbl = series->get_DataPoints()->idx_get(0)->get_Label(); lbl->get_DataLabelFormat()->set_ShowCategoryName(true); lbl = series->get_DataPoints()->idx_get(1)->get_Label(); lbl->get_DataLabelFormat()->set_ShowSeriesName(true); // Show value for third label lbl = series->get_DataPoints()->idx_get(2)->get_Label(); lbl->get_DataLabelFormat()->set_ShowValue(true); lbl->get_DataLabelFormat()->set_ShowSeriesName(true); lbl->get_DataLabelFormat()->set_Separator(u"/"); // Save PPTX file pres->Save(outputFilePath, Aspose::Slides::Export::SaveFormat::Pptx);
