Hur man lägger till ett PivotDiagram med C++

Vad är PivotChart

Ett pivotdiagram är en visuell representation av datan i en pivottabell. Pivotdiagram ger ett sätt att sammanfatta, analysera, utforska och presentera summerad data. Här är några nyckelfunktioner och aspekter av pivotdiagram:

  1. Dynamisk datarapportering: Pivotdiagram uppdateras automatiskt för att återspegla förändringar i pivottabellen. Om du lägger till eller tar bort fält i pivottabellen, uppdateras pivotdiagrammet därefter.

  2. Interaktiv: Pivotdiagram är interaktiva, vilket tillåter användare att filtrera, sortera och fördjupa sig i data. Detta gör det enkelt att utforska olika aspekter av datamängden.

  3. Flexibelt layout: Användare kan ändra layouten på pivotdiagrammet genom att dra och släppa fält, vilket ger flexibilitet i hur data visualiseras.

  4. Olika diagramtyper: Pivotdiagram kan skapas med olika diagramtyper som stapeldiagram, linjediagram, cirkeldiagram och fler, beroende på datans natur och insseiten du vill få.

  5. Sammanfattning: Pivotdiagram sammanfattar stora datamängder och kan visa totalsummor, medelvärden, antal eller andra sammanfattande statistik.

  6. Filtrering: De erbjuder filtreringsmöjligheter, vilket gör att du kan visa endast den data som uppfyller vissa kriterier.


Pivotdiagram används ofta inom affärsintelligens och dataanalys för att ge en tydlig och koncis visuell sammanfattning av komplexa datamängder. De är ett kraftfullt verktyg för datadrivna beslut.

Hur man lägger till en PivotChart med hjälp av Aspose.Cells

Lägga till en pivottabell

För att skapa en pivot tabell med Aspose.Cells:

  1. Lägg till data i ett kalkylblad med hjälp av Cell-objektets PutValue eller SetValue metod. Du kan också använda en mallfil som redan är ifylld med data. Data kommer att användas som datakälla för pivot-tabellen.
  2. Lägg till en pivot-tabell i kalkylbladet genom att anropa PivotTables-samlingen Add-metod (inkapslad i Worksheet-objektet).
  3. Få tillgång till det nya PivotTable-objektet från PivotTables-samlingen genom att ange dess index. Använd något av pivot-tabellobjekten som kapslas in i PivotTable-objektet för att hantera tabellen.

Kodexempel ges nedan.

Lägga till en PivotChart

För att skapa en PivotChart med Aspose.Cells:

  1. Lägg till en graf.
  2. Ställ in PivotSource för diagrammet att hänvisa till en befintlig pivot-tabell i kalkylbladet.
  3. Ange andra attribut.
#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);
