Kreisdiagramm mit Führungslinien erstellen
Um die Verwendung von Aspose.Cells for .NET API zum Erstellen eines Kreisdiagramms mit Führungslinien zu demonstrieren, erstellen wir zunächst ein neuesArbeitsmappe und geben Sie einige Daten ein, die als Datenquelle für die Serie dienen. Sobald die Daten vorhanden sind, werden wir a hinzufügenDiagramm des TypsChartType.Piezur Sammlung von Diagrammen und stellen Sie die verschiedenen Aspekte ein, um die gewünschte Diagrammansicht zu erhalten.

Bisher haben wir ein Tortendiagramm erstellt und seine verschiedenen Aspekte festgelegt. Jetzt werden wir die Führungslinien für das Diagramm einschalten. Bitte beachten Sie, dass wir die Datenbeschriftungen ein wenig verschieben müssen, um die Führungslinien anzuzeigen.
Der folgende Codeabschnitt aktiviert die Führungslinien, aktualisiert das Diagramm und berechnet dann die Positionen der Datenbeschriftungen, um sie entsprechend zu verschieben.
