Ist es möglich, nur den unteren Teil eines Diagramms abzuschneiden? Ich habe ein Diagramm mit einem Knoten über dem Bereich davon. Wenn das Abschneiden über das gesamte Objekt aktiviert ist, wird der Knoten abgeschnitten. Kein Abschneiden bedeutet jedoch, dass die Funktion leicht über die untere x-Achse hinausgeht.
Nehmen Sie Folgendes in Ihre Präambel auf:
