如何使用Aspose.Cells添加数据透视图

什么是数据透视图

数据透视表是数据的可视表示。数据透视图提供了一种总结、分析、探索和展示汇总数据的方法。以下是数据透视表的一些关键特性和方面：

1. 动态数据表示：数据透视图会自动更新以反映数据透视表中的更改。如果在数据透视表中添加或删除字段，数据透视图会相应地更新。

2. 交互式：数据透视图是交互式的，允许用户对数据进行筛选、排序和深入分析。这使得探索数据集的不同方面变得容易。

3. 灵活布局：用户可以通过拖放字段来更改数据透视图的布局，从而灵活可视化数据。

4. 各种图表类型：根据数据的性质和您希望获得的见解，可以使用各种图表类型来创建数据透视图，例如柱状图、折线图、饼图等。

5. 汇总：数据透视图总结大量数据并可显示总计、平均值、计数或其他汇总统计信息。

6. 筛选：它们提供筛选功能，允许您仅显示符合特定标准的数据。

数据透视图通常用于商业智能和数据分析，以对复杂数据集提供清晰简洁的可视汇总。它们是做出基于数据的决策的强大工具。

如何使用Aspose.Cells添加数据透视图

添加数据透视表

使用Aspose.Cells创建数据透视表：

1. 使用Cell对象的PutValue/setValue方法向工作表单元格添加一些数据。您还可以使用已填充数据的模板文件。这些数据将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。

添加数据透视图

使用Aspose.Cells创建数据透视图：

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。

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

// Instantiating an Workbook object
// Opening the excel file
Workbook workbook = new Workbook(dataDir+ "pivotTable_test.xlsx");
// Adding a new sheet
Worksheet sheet3 = workbook.Worksheets[workbook.Worksheets.Add(SheetType.Chart)];
// Naming the sheet
sheet3.Name = "PivotChart";
// Adding a column chart
int index = sheet3.Charts.Add(Aspose.Cells.Charts.ChartType.Column, 0, 5, 28, 16);
// Setting the pivot chart data source
sheet3.Charts[index].PivotSource = "PivotTable!PivotTable1";
sheet3.Charts[index].HidePivotFieldButtons = false;
// Saving the Excel file
workbook.Save(dataDir+ "pivotChart_test_out.xlsx");
