Ich habe einen Fehler mit der Aktualisierung von Daten auf LineChart bekommen. Nach dem Aktualisieren von LineChart x Werte nicht gut aktualisiert. Sieht so aus, als ob neue Werte aus der Funktion "gemischt" sind. Nach der Implementierung von Wave packetJavaFX Liniendiagramm wird nicht gut aktualisiert. Datenprobleme
Mit dispersive und ohne es, sollte auf der aktuellen Animation aus Wikipedia rechten Seite der Seite für beide Fälle aussehen. Ich versuche dieses Problem zu finden, was falsch ist, aber ehrlich gesagt kann ich das nicht sehen. Zählen von Daten ist ziemlich sicher in 100% gut. Ich rötete mich irgendwo über diese Art von Problemen, konnte aber mein Problem nicht lösen.

Für extrimly hoch für diese Art von equantion x Werte, die wir dort beobachten können, ist hugh Chaos mit Daten, sollten geht reibungslos wie bei Wikipedia Sample, aber es nicht. Kann mir jemand sagen, wo das Problem ist? Es ist auch sehr schlaff während der Verwendung kleiner x/y Tick und größer x und y Achsen. Was dafür? Vielen Dank im Voraus.
P.S. 
SS zeigt, wie es nach einiger Aktualisierung des Liniendiagramms aussieht.
