如何用C++添加透视图表

什么是数据透视图

透视图表是数据透视表的可视化表现形式。透视图表提供了汇总、分析、探索和展示汇总数据的方式。以下是透视图表的一些主要功能和特性：

  1. 动态数据表现：透视图表会自动更新以反映数据透视表的变化。若添加或删除字段，图表相应变动。

  2. 交互性：透视图表支持交互操作，用户可以筛选、排序或深入探索数据。这使得分析更便捷。

  3. 布局灵活：用户可以通过拖放字段改变透视图表的布局，增强可定制性。

  4. 多种图表类型：透视图表支持柱状图、线图、饼图等多种类型，根据数据特性和分析需求定制。

  5. 汇总统计：透视图表可以汇总大量数据，并显示总计、平均值、计数或其他统计结果。

  6. 筛选功能：提供筛选功能，只显示符合条件的数据。


透视图表常用于商业智能和数据分析，帮助客户清晰、简洁地展示复杂数据，是做出数据驱动决策的强大工具。

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 或 SetValue 方法向工作表单元格添加数据。您也可以使用已填充数据的模板文件。数据将用作枢轴表的数据源。
  2. 通过调用PivotTables集合的Add方法（封装在Worksheet对象中）向工作表添加数据透视表。
  3. 通过传递索引从PivotTables集合中访问新的PivotTable对象。使用任何封装在PivotTable对象中的数据透视表对象来管理表格。

下面是代码示例。

#include <iostream>
#include "Aspose.Cells.h"
using namespace Aspose::Cells;

int main()
{
    Aspose::Cells::Startup();

    // Source directory path
    U16String srcDir(u"..\\Data\\01_SourceDirectory\\");

    // Output directory path
    U16String outDir(u"..\\Data\\02_OutputDirectory\\");

    // Create a new workbook
    Workbook workbook;

    // Get the first worksheet
    Worksheet sheet = workbook.GetWorksheets().Get(0);

    // Name the sheet
    sheet.SetName(u"Data");

    // Get the cells collection
    Cells cells = sheet.GetCells();

    // Setting the values to the cells
    Cell cell = cells.Get(u"A1");
    cell.PutValue(u"Employee");
    cell = cells.Get(u"B1");

添加数据透视图

使用Aspose.Cells创建数据透视图：

  1. 添加图表。
  2. 设置图表的PivotSource，指向工作表中的现有数据透视表。
  3. 设置其他属性。
#include <iostream>
#include "Aspose.Cells.h"
using namespace Aspose::Cells;
using namespace Aspose::Cells::Charts;

int main()
{
    Aspose::Cells::Startup();

    // Source directory path
    U16String srcDir(u"..\\Data\\01_SourceDirectory\\");

    // Output directory path
    U16String outDir(u"..\\Data\\02_OutputDirectory\\");

    // Path of input excel file
    U16String inputFilePath = srcDir + u"pivotTable_test.xlsx";

    // Path of output excel file
    U16String outputFilePath = outDir + u"pivotChart_test_out.xlsx";

    // Create workbook
    Workbook workbook(inputFilePath);

    // Adding a new sheet
    int sheetIndex = workbook.GetWorksheets().Add(SheetType::Chart);
    Worksheet sheet3 = workbook.GetWorksheets().Get(sheetIndex);

    // Naming the sheet
    sheet3.SetName(u"PivotChart");

    // Adding a column chart
    int index = sheet3.GetCharts().Add(ChartType::Column, 0, 5, 28, 16);

    // Setting the pivot chart data source
    sheet3.GetCharts().Get(index).SetPivotSource(u"PivotTable!PivotTable1");
    sheet3.GetCharts().Get(index).SetHidePivotFieldButtons(false);

    // Saving the Excel file
    workbook.Save(outputFilePath);

    std::cout << "Pivot chart created successfully!" << std::endl;

    Aspose::Cells::Cleanup();
