Aspose.Words for .NET使用教程（十三）：从Scratch创建OOXML图表（上）

Aspose.Words无需Microsoft Word也可在任何平台上满足Word文档的一切操作需求。本文将与大家分享如何插入柱形图到文档中。

Aspose.Word提供了 InsertChart 方法，该方法已添加到 DocumentBuilder 类中。那么，让我们看看如何使用 DocumentBuilder-> InsertChart 方法将简单的柱形图插入到文档中：

如何插入柱形图。

下面的示例代码显示了如何插入柱形图。

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);

该代码会产生以下结果：

Add系列方法有四种不同的重载，它们涵盖了所有图表类型的所有可能的数据源变体：

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);

该代码会产生以下结果：
