Ich verwende die Google-Diagramme Treemap, um eine sehr große Anzahl von Knoten anzuzeigen. Das Standardverhalten besteht darin, sich in der Struktur nach unten zu bewegen, wenn ein Benutzer mit der linken Maustaste auf einen Knoten klickt und sich in der Struktur nach oben bewegt, wenn ein Benutzer mit der rechten Maustaste auf die Grafik klickt. Klicken Sie mit der rechten Maustaste, um das Diagramm für jeden Klick neu zu zeichnen. Das Neuzeichnen ist wegen der großen Anzahl von Knoten sehr langsam. Wie deaktiviere ich die Knoten-Abwärtsbewegung, ohne das Mausklick-Ereignis zu deaktivieren? Wie kann man die Leistung von Treemap Draw verbessern?Deaktivieren Sie eine Verschiebung in Google Charts Treemap

Dank

der Knoten nach unten bewegen Funktion auftritt, wenn ein Diagrammelement

zu disable ausgewählt wird, um die Auswahl löschen, wenn die 'select' Ereignis ausgelöst

tree.setSelection([]);

Diese verhindert, dass das Diagramm die nächste Ebene anzeigt ...
