Einstellen der Titel von Diagrammen oder Achsen
Sie können Microsoft Excel verwenden, um in einer WYSIWYG-Umgebung die Titel eines Diagramms und seiner Achsen festzulegen. Aspose.Cells for JavaScript über C++ erlaubt es auch Entwicklern, die Titel eines Diagramms und seiner Achsen zur Laufzeit festzulegen. Alle Diagramme und ihre Achsen enthalten eine Title Eigenschaft, mit der ihre Titel wie im folgenden Beispiel gesetzt werden können.
Das folgende Codebeispiel zeigt, wie man Titel für Diagramme und Achsen setzt.
