Ich versuche drei Antworten auf eine Reihe von Variablen auf zwei Achsen Plot mit R-Basis-Grafiken zu plotten. Ähnliche Zahlen kommen gut heraus, aber mit einigen meiner Datensätze flammen die Kurven zum höheren Ende des Bereichs von x auf. Ich habe keine doppelten Y-Werte (außer dort, wo sich die Kurven kreuzen).Warum flimmern Kurven in zwei Achsen?

Warum flimmern die Kurven so? Ist es ein Problem mit dem Skript oder mit den Daten?

Plot, Skript und Daten sind unten.

Ihre x-Werte nicht sortiert sind, so sind die Parzellen Linien horizontal hin und her zu ziehen. Wenn Sie die Daten zuerst anhand der x-Werte sortieren, wird dies nicht mehr angezeigt.
