Beispiele

Im folgenden Codebeispiel wird veranschaulicht, wie Sie der Entwurfsoberfläche eine Schwellenwertlinie hinzufügen, nachdem das Diagrammsteuerelement hinzugefügt wurde. Das Diagramm verwendet eine nicht wiederkehrende Streifenlinie, um eine Berechnung des Mittelwerts aller Datenpunkte in einer Datenreihe anzuzeigen.

Hinweise

Wenn diese Eigenschaft auf einen Wert festgelegt Autoist, wird der Text basierend auf dem Diagrammtyp ausgerichtet. Bei allen anderen X-Y-Diagrammtypen als Balken wird der Text der X-Achse horizontal von links nach rechts am unteren Rand der Streifenlinie ausgerichtet. Bei Balkendiagrammen wird der Text der X-Achse von oben nach unten rechts von der Streifenlinie vertikal ausgerichtet.
