Was ist ein PivotChart
Ein Pivot-Chart ist eine visuelle Darstellung der Daten in einer Pivot-Tabelle. Pivot-Charts bieten eine Möglichkeit, Zusammenfassungen zu erstellen, zu analysieren, zu erkunden und präsentabel zu machen. Hier sind einige wichtige Funktionen und Aspekte von Pivot-Charts:
-
Dynamische Datenrepräsentation: Pivot-Charts aktualisieren sich automatisch, um Änderungen an der Pivot-Tabelle widerzuspiegeln. Wenn Felder in der Pivot-Tabelle hinzugefügt oder entfernt werden, wird das Pivot-Chart entsprechend aktualisiert.
-
Interaktiv: Pivot-Charts sind interaktiv, ermöglichen es Benutzern, Daten zu filtern, zu sortieren und zu vertiefen. Dadurch ist es einfach, verschiedene Aspekte des Datensatzes zu erkunden.
-
Flexibles Layout: Benutzer können das Layout des Pivot-Diagrams durch Ziehen und Ablegen von Feldern ändern, was Flexibilität bei der Visualisierung von Daten bietet.
-
Verschiedene Diagrammtypen: Pivot-Diagramme können mit verschiedenen Diagrammtypen wie Säulendiagrammen, Liniendiagrammen, Kreisdiagrammen und mehr erstellt werden, je nach Art der Daten und den gewünschten Erkenntnissen.
-
Zusammenfassung: Pivot-Diagramme fassen große Datenmengen zusammen und können Summen, Durchschnitte, Zählen oder andere Zusammenfassungsstatistiken anzeigen.
-
Filtern: Sie bieten Filterfunktionen, mit denen nur Daten angezeigt werden, die bestimmte Kriterien erfüllen.
Pivot-Diagramme werden häufig in Business Intelligence und Datenanalyse verwendet, um eine klare und prägnante visuelle Zusammenfassung komplexer Datensätze zu bieten. Sie sind ein mächtiges Werkzeug, um datengetriebene Entscheidungen zu treffen.

Hinzufügen einer Pivot-Tabelle
Um eine Pivot-Tabelle mit Aspose.Cells für Python via .NET zu erstellen:
- Fügen Sie einige Daten in Zellen eines Arbeitsblatts mit der PutValue/setValue-Methode eines Cell-Objekts ein. Sie können auch eine Vorlagendatei verwenden, die bereits mit Daten gefüllt ist. Die Daten werden als Datenquelle der Pivot-Tabelle verwendet.
- Fügen Sie dem Arbeitsblatt eine Pivot-Tabelle hinzu, indem Sie die Methode add der PivotTables-Sammlung aufrufen (die im Arbeitsblatt-Objekt gekapselt ist).
- Greifen Sie auf das neue PivotTable-Objekt aus der PivotTables-Sammlung zu, indem Sie seinen Index übergeben. # Verwenden Sie eines der in dem PivotTable-Objekt gekapselten Pivot-Tabellenobjekte, um die Tabelle zu verwalten.
