Ich habe beobachtet, dass die Funktionalität von "Zoom-In" und "Zoom-Out" ganz anders als erwartet umgesetzt wurde. Wie zum Beispiel wenn ich einen Schritt "Zoom-out" mache und dann wieder nach einem Schritt von " Hineinzoomen". Ich konnte das Originaldiagramm nicht mehr sehen.Abnormales Verhalten der Zoom- und Zoom-Out-Funktionalität des JFreeChart?
Ich sehe "Zoom-In" und "Zoom-Out" -Funktion von JFrechart nicht in der Synchronisierung.

Problem2: Nach zwei Klicks auf ZoomInX 
Und wieder nach zwei Klicks auf ZoomOutX (die die ursprüngliche Graph ist) 
aber wieder nach zwei Klicks auf ZoomInX sehe ich die Grafik ein anderes, nicht als das erste Bild in dieser Frage, die sein sollte. 
Ich habe die Frage mit dem Beispielcode aktualisiert, den ich versuchte. – JAVA
