Wie man ein Wasserfalldiagramm erstellt

Contents
[ ]

Aspose.Cells für Python via .NET APIs ermöglichen es, mit Hilfe eines Liniendiagramms ein Wasserfalldiagramm zu erstellen. Die API erlaubt auch die Anpassung des Diagramm-Aussehens, um die Form eines Wasserfalls durch Setzen der Series.up_bars- und Series.down_bars-Eigenschaften zu erhalten.

Nachstehender Codeausschnitt zeigt, wie man die Aspose.Cells für Python via .NET API verwendet, um ein Wasserfalldiagramm von Grund auf neu zu erstellen.
