Aspose.Words for C++提供了 InsertChart 方法，該方法已添加到 DocumentBuilder 類中。那么，讓我們看看如何使用 DocumentBuilder-> InsertChart 方法將簡單的柱形圖插入到文檔中：

如何插入柱形圖。

下面的示例代碼顯示了如何插入柱形圖。

System::SharedPtr<Document> doc = System::MakeObject<Document>();
System::SharedPtr<DocumentBuilder> builder = System::MakeObject<DocumentBuilder>(doc);

// Add chart with default data. You can specify different chart types and sizes.
System::SharedPtr<Shape> shape = builder->InsertChart(ChartType::Column, 432, 252);

// Chart property of Shape contains all chart related options.
System::SharedPtr<Chart> chart = shape->get_Chart();

// Get chart series collection.
System::SharedPtr<ChartSeriesCollection> seriesColl = chart->get_Series();
// Check series count.
std::cout << seriesColl->get_Count() << std::endl;

// Delete default generated series.
seriesColl->Clear();

// Create category names array, in this example we have two categories.
System::ArrayPtr<System::String> categories = System::MakeArray<System::String>({u"AW Category 1", u"AW Category 2"});

// Adding new series. Please note, data arrays must not be empty and arrays must be the same size.
seriesColl->Add(u"AW Series 1", categories, System::MakeArray<double>({1, 2}));
seriesColl->Add(u"AW Series 2", categories, System::MakeArray<double>({3, 4}));
seriesColl->Add(u"AW Series 3", categories, System::MakeArray<double>({5, 6}));
seriesColl->Add(u"AW Series 4", categories, System::MakeArray<double>({7, 8}));
seriesColl->Add(u"AW Series 5", categories, System::MakeArray<double>({9, 10}));

System::String outputPath = dataDir + GetOutputFilePath(u"CreateColumnChart.InsertSimpleColumnChart.doc");
doc->Save(outputPath);

該代碼會產(chǎn)生以下結(jié)果：

Add系列方法有四種不同的重載，它們涵蓋了所有圖表類型的所有可能的數(shù)據(jù)源變體：

System::SharedPtr<Document> doc = System::MakeObject<Document>();
System::SharedPtr<DocumentBuilder> builder = System::MakeObject<DocumentBuilder>(doc);

// Insert Column chart.
System::SharedPtr<Shape> shape = builder->InsertChart(ChartType::Column, 432, 252);
System::SharedPtr<Chart> chart = shape->get_Chart();

// Use this overload to add series to any type of Bar, Column, Line and Surface charts.
chart->get_Series()->Add(u"AW Series 1", System::MakeArray<System::String>({u"AW Category 1", u"AW Category 2"}), System::MakeArray<double>({1, 2}));

System::String outputPath = dataDir + GetOutputFilePath(u"CreateColumnChart.InsertColumnChart.doc");
doc->Save(outputPath);

該代碼會產(chǎn)生以下結(jié)果：
