Skapa pivottabeller och pivottabell diagram med C++

En pivottabell är en interaktiv sammanställning av poster. Till exempel kan du ha hundratals fakturaposter i en lista i ett kalkylblad. En pivottabell kan sammanställa fakturor efter kund, produkt eller datum. Med Microsoft Excel är det möjligt att snabbt omorganisera informationen i pivottabellen genom att dra knappar till en ny position.

Ett pivotdiagram är en interaktiv grafisk representation av data i en pivottabell. Pivotdiagram introducerades i Excel 2000. Att använda ett pivotdiagram gör det ännu enklare att förstå data eftersom pivottabellen skapar delsummer och totaler automatiskt.

Aspose.Cells stöder pivottabeller och pivottabell-diagram.

Lägg till Pivottabeller och Diagram

Aspose.Cells tillhandahåller en speciell uppsättning klasser som används för att skapa pivottabeller. Dessa klasser används för att skapa och ställa in PivotTable-objekt, som fungerar som en pivottabells grundläggande byggstenar:

PivotField, ett fält i en pivottabellsrapport.
PivotFields, en samling av alla PivotField-objekt i en pivottabell.
PivotTable, en Pivottabell-rapport i ett kalkylblad.
PivotTables, en samling av alla PivotTable-objekt på kalkylbladet.

Förberedelser för att använda Aspose.Cells

Ladda ner och installera Aspose.Cells:
1. Ladda ner Aspose.Cells.
2. Installera det på din utvecklingsdator. Alla Aspose-komponenter, när de är installerade, fungerar i utvärderingsläge. Utvärderingsläget har ingen tidsbegränsning och infogar endast vattenstämplar i genererade dokument. För att arbeta med komponenten i dess fulla kapacitet, måste du ha en giltig licens.
Skapa ett projekt:
1. Starta din C++-IDE (t.ex. Visual Studio).
2. Skapa en ny konsolapplikation.
Lägg till referenser: Lägg till referens till Aspose.Cells-komponenten i ditt projekt, till exempel, ...\Program Files\Aspose\Aspose.Cells\Bin\Net1.0\Aspose.Cells.dll.

Lägga till en pivottabell

För att skapa en pivot tabell med Aspose.Cells:

Lägg till data i ett kalkylblad genom att använda PutValue-metoden för ett Cell-objekt. Du kan även använda en mallfil som redan är fylld med data. Data kommer att användas som pivot-tabellens datakälla.
Lägg till en pivot-tabell i kalkylbladet genom att anropa PivotTables-samlingen Add-metod (inkapslad i Worksheet-objektet).
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.

Lägga till en PivotChart

För att skapa en PivotChart med Aspose.Cells:

Lägg till en graf.
Ställ in PivotSource för diagrammet att hänvisa till en befintlig pivot-tabell i kalkylbladet.
Ange andra attribut.

#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\\");

    // 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
    Worksheet sheet3 = workbook.GetWorksheets().Get(workbook.GetWorksheets().Add(SheetType::Chart));

    // 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();
