创建数据透视表和数据透视图

数据透视表是记录的互动摘要。例如，您可能有数百个工作表中列表中的发票条目。数据透视表可以按客户、产品或日期总计发票。使用Microsoft Excel，可以通过将按钮拖到新位置，快速重新排列数据透视表中的信息。

数据透视图图表是数据透视表中数据的交互式图形表示。数据透视图图表在Excel 2000中引入。使用数据透视图图表使数据更容易理解，因为数据透视表会自动创建小计和总计。

Aspose.Cells for Node.js via C++ 支持 数据透视表 和 数据透视图。

使用Aspose.Cells for Node.js via C++添加数据透视表和图表

Aspose.Cells for Node.js via C++ 提供了一组用于创建数据透视表的特殊类。这些类用于创建和设置数据透视表对象，它们作为数据透视表对象的基本构建块：

• PivotField，数据透视表报告中的字段。
• PivotFields，数据透视表中所有 PivotField 对象的集合。
• 一个工作表上的数据透视表。
• 数据透视表是工作表上所有数据透视表对象的集合。

准备使用 Aspose.Cells for Node.js via C++

1. 从 NPM 安装 Aspose.Cells for Node.js via C++，使用命令：$ npm install aspose.cells.node。
2. 你也可以按照逐步指引将“Aspose.Cells for Node.js via C++”安装到你的开发环境中。

如何使用 Aspose.Cells for Node.js via C++ 添加数据透视表

使用 Aspose.Cells for Node.js via C++ 创建数据透视表的方法：

1. 使用Cell对象的put_value方法向工作表单元格添加一些数据。也可以使用填充了数据的模板文件。这些数据将被用作数据透视表的数据源。
2. 通过调用PivotTables集合的add方法（封装在Worksheet对象中）向工作表添加一个数据透视表。
3. 通过传入索引从PivotTables集合中访问新的 PivotTable 对象。# 使用 PivotTable 对象中封装的任何数据透视表对象来管理表。

下面是代码示例。

如何使用 Aspose.Cells for Node.js via C++ 库添加数据透视图

使用 Aspose.Cells for Node.js via C++ 创建数据透视图的方法：

1. 添加图表。
2. 将图表的数据源设置为引用电子表格中的现有数据透视表。
3. 设置其他属性。

const AsposeCells = require("aspose.cells.node");

//For complete examples and data files, please go to https:# github.com/aspose-cells/Aspose.Cells-for-.NET
//The path to the documents directory.
var dataDir = RunExamples.GetDataDir(".");
//Instantiating an Workbook object
//Opening the excel file
var workbook = new AsposeCells.Workbook(dataDir + "pivotTable_test.xlsx");
//Adding a new sheet
var sheet3 = workbook.getWorksheets().get(workbook.getWorksheets().add(AsposeCells.SheetType.Chart));
//Naming the sheet
sheet3.setName("PivotChart");
//Adding a column chart
index = sheet3.getCharts().add(AsposeCells.ChartType.Column, 0, 5, 28, 16);
//Setting the pivot chart data source
sheet3.getCharts().get(index).setPivotSource("PivotTable!PivotTable1");

sheet3.getCharts().get(index).setHidePivotFieldButtons(false);
//Saving the Excel file
workbook.save(dataDir + "pivotChart_test_out.xlsx");
