Ich habe es geschafft, ein gut aussehendes Diagramm zu erstellen, möchte aber eine „Schleife“ hinzufügen, die auf einen von mir festgelegten Schwellenwert (das 95. Perzentil) zoomt. In das gezoomte Bild möchte ich Text einfügen können (um zu zeigen, welchen Wert x und y haben). Ist das möglich? Unten habe ich eine Abbildung erstellt, wie es aussehen soll, wobei der Code ganz unten steht (tut mir leid wegen der Menge an Datenpunkten).

Antwort1
Diese Antwort zeigt nur einige geringfügige Verbesserungen anMurmeltier hat schon eine tolle Antwort. Ich definiere die zu vergrößernde KoordinateErsteund dann diese Koordinate verwenden, um die roten gestrichelten Linien hinzuzufügen, den Knoten "on spy" zu platzieren und die Koordinaten des zu vergrößernden Punktes unter die Vergrößerung zu schreiben. (Ich habe mich auch entschieden, den Koordinatentextuntendie Vergrößerung, da sich dann nichts überlappt.)
Weitere Einzelheiten entnehmen Sie bitte den Kommentaren zum Code.
