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支持 数据透视表 和 数据透视图。

添加数据透视表和数据透视图

Aspose.Cells 提供了一组特殊的类，用于创建数据透视表。这些类用于创建和设置 PivotTable 对象，作为数据透视表对象的基本构建快：

• 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

1. 下载并安装Aspose.Cells.Zip：
   1. 下载Aspose.Cells for Java.
   2. 在开发计算机上解压缩。 所有 Aspose 组件在安装后都是以评估模式运行。 评估模式没有时间限制，只会在生成的文档中添加水印。
2. 创建一个项目
   1. 您可以使用Java编辑器（例如Eclipse）创建项目，或者使用NotePad创建一个简单的程序。
3. 添加类路径： 在Eclipse中设置类路径：
   1. 从 Aspose.Cells.zip 中提取 Aspose.Cells.jar 和 dom4j_1.6.1.jar。
   2. 在 Eclipse 的项目中设置类路径：
   3. 在Eclipse中选择您的项目，然后点击菜单Project-Properties。
   4. 在弹出窗口的左侧选择“Java Build Path”，然后选择“Libraries”选项卡，单击“Add JARs”或“Add External JARs”以选择Aspose.Cells.jar和dom4j_1.6.1.jar，并将它们添加到构建路径中。
   5. 编写调用Aspose组件API的应用程序。 或者您可以在Windows的dos提示符下在运行时设置它。

 javac \-classpath %classpath%;e:\Aspose.Cells.jar; ClassName .javajava \-classpath %classpath%;e:\Aspose.Cells.jar; ClassName 

创建数据透视表

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. 通过传递其索引从PivotTables集合中访问新的PivotTable对象。
4. 使用PivotTable对象中封装的任何数据透视表对象来管理表。

下面给出了一段代码示例。执行该代码将生成一个新文件：pivotTable_test.xls。

基于数据透视表创建数据透视图

使用Aspose.Cells创建一个数据透视图:

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。

以下是组件用于完成任务的代码。执行代码会生成一个新文件：pivotChart_test.xls。

数据透视图表工作表

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java
// The path to the documents directory.
String dataDir = Utils.getDataDir(CreatePivotChartbasedonPivotTable.class);
// Instantiating an Workbook object
Workbook workbook = new Workbook(dataDir + "pivotTable_test.xls");
// Adding a new sheet
int sheetIndex = workbook.getWorksheets().add(SheetType.CHART);
Worksheet sheet3 = workbook.getWorksheets().get(sheetIndex);
// Naming the sheet
sheet3.setName("PivotChart");
// Adding a column chart
int chartIndex = sheet3.getCharts().add(ChartType.COLUMN, 0, 5, 28, 16);
Chart chart = sheet3.getCharts().get(chartIndex);
// Setting the pivot chart data source
chart.setPivotSource("PivotTable!PivotTable1");
chart.setHidePivotFieldButtons(false);
// Saving the Excel file
workbook.save(dataDir + "pivotChart_test.xls");
