### 创建 PPT 文件图表 - C++

```cs
// Output File Path.
const String outputFilePath = u"OutputDirectory\\column_chart.ppt";

// Instantiate Presentation class
SharedPtr<Presentation> pres = MakeObject<Presentation>();

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

// Add chart with default data
SharedPtrv<IChart> chart = 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
SharedPtr<IChartDataWorkbook> fact = 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<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 categories
chart->get_ChartData()->get_Categories()->Add(fact->GetCell(defaultWorksheetIndex, 1, 0, ObjectExt::Box<System::String>(u"Category 1")));
chart->get_ChartData()->get_Categories()->Add(fact->GetCell(defaultWorksheetIndex, 2, 0, ObjectExt::Box<System::String>(u"Category 2")));
chart->get_ChartData()->get_Categories()->Add(fact->GetCell(defaultWorksheetIndex, 3, 0, ObjectExt::Box<System::String>(u"Category 3")));

// Take first chart series
SharedPtr<IChartSeries> series = 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
SharedPtr<IDataLabel> lbl = 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 PPT file
pres->Save(outputFilePath, Aspose::Slides::Export::SaveFormat::Ppt);

```

## 关于 Aspose.Slides for C++ API

 .现场演示有以下好处

A file with PPT extension represents PowerPoint file that consists of a collection of slides for displaying as SlideShow. It specifies the Binary File Format used by Microsoft PowerPoint 97-2003. A PPT file can contain several different types of information such as text, bulleted points, images, multimedia and other embedded OLE objects. Microsoft came up with newer file format for PowerPoint, known as PPTX, from 2007 onwards that is based on Office OpenXML and is different from this binary file format. Several other application programs such as OpenOffice Impress and Apple Keynote can also create PPT files.
