Skapa pivottabeller och pivotdiagram

En pivottabell är en interaktiv sammanfattning av poster. Till exempel kan du ha hundratals faktura-poster i en lista i ett kalkylblad. En pivottabell kan summera fakturorna 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 for Node.js via C++ stöder pivot-tabeller och pivot-diagram.

Lägg till pivot-tabeller och diagram med Aspose.Cells for Node.js via C++

Aspose.Cells for Node.js via C++ tillhandahåller en särskild uppsättning klasser för att skapa pivot-tabeller. Dessa klasser används för att skapa och ställa in PivotTable-objekt, som fungerar som grundläggande byggstenar för en PivotTable:

• PivotField, ett fält i en pivottabellrapport.
• PivotFields, en samling av alla PivotField-objekt i en pivottabell.
• PivotTable, en pivottabellrapport på ett kalkylblad.
• PivotTables, en samling av alla PivotTable-objekt på kalkylbladet.

Förbered att använda Aspose.Cells for Node.js via C++

1. Installera Aspose.Cells for Node.js via C++ från NPM, använd kommandot: $ npm install aspose.cells.node.
2. Du kan också följa steg-för-steg-instruktionerna för att installera “Aspose.Cells for Node.js via C++” i din utvecklarmiljö.

Hur man lägger till en Pivot-tabell med Aspose.Cells for Node.js via C++

För att skapa en pivot-tabell med Aspose.Cells for Node.js via C++:

1. Lägg till lite data i ett kalkylbladsceller med hjälp av en Cell-objekts put_value-metod. Du använder också en mallfil som redan är ifylld med data. Datan kommer att användas som pivottabellens datakälla.
2. Lägg till en pivot tabell till arbetsbladet genom att anropa PivotTables -samlingens add-metod (inkapslad i Worksheet-objektet).
3. Hämta det nya PivotTable-objektet från PivotTables-samlingen genom att ange dess index. # Använd något av de pivottabellobjekt som är inkapslade i PivotTable-objektet för att hantera tabellen.

Hur man lägger till ett Pivot-diagram med Aspose.Cells for Node.js via C++-biblioteket

För att skapa ett PivotDiagram med Aspose.Cells for Node.js via C++:

1. Lägg till en graf.
2. Ange grafens PivotSource så att den hänvisar till en befintlig pivot tabell i kalkylarket.
3. Ange andra attribut.

const AsposeCells = require("aspose.cells.node");

//For complete examples and data files, please go to https:# github.com/aspose-cells/Aspose.Cells-for-.NET
//The path to the documents directory.
var dataDir = RunExamples.GetDataDir(".");
//Instantiating an Workbook object
//Opening the excel file
var workbook = new AsposeCells.Workbook(dataDir + "pivotTable_test.xlsx");
//Adding a new sheet
var sheet3 = workbook.getWorksheets().get(workbook.getWorksheets().add(AsposeCells.SheetType.Chart));
//Naming the sheet
sheet3.setName("PivotChart");
//Adding a column chart
index = sheet3.getCharts().add(AsposeCells.ChartType.Column, 0, 5, 28, 16);
//Setting the pivot chart data source
sheet3.getCharts().get(index).setPivotSource("PivotTable!PivotTable1");

sheet3.getCharts().get(index).setHidePivotFieldButtons(false);
//Saving the Excel file
workbook.save(dataDir + "pivotChart_test_out.xlsx");
