Dies ist eine sehr spezifische Frage zu zwei Objekten von Tikz-Zeichnungen. Das erste zeigt Folgendes:
Das zweite stammt aus dieser Diskussion:Krähenfuß-ERM auf nette Art
Ich muss die tikset{oder tikzpicture{Einstellungen ändern, damit beide funktionieren.
dies ist ein MWE:

Wie kann ich den ersten Teil ändern, damit beides funktioniert?
Bearbeiten: es scheint, als gäbe es ein weiteres Problem, das ich mit dem MWE nicht reproduzieren kann. Dies ist ein Screenshot des Fehlercodes. Ich habe keine Ahnung, wo sich der Thinspace (U+2009) befindet ... das Inputenc-Handbuch zeigt auch auf Seite 4 keine hilfreicheren Informationen. (oder ich verstehe den Sinn nicht ...) Jede Hilfe ist willkommen ...
Antwort1
Der erste Teil gibt mit oder ohne den zweiten Teil einen Fehler aus, da der Schlüssel arrownicht definiert ist.
Fügen Sie die Zeile hinzu
\tikzset{arrow/.style={-stealth})
zur Präambel.
