PCLoggingWie kann ich auf den Pfeil (vorzugsweise in der Mitte) zwischen den Kästchen und einen vertikalen, nach oben zeigenden Pfeil setzen STP?
Antwort1
Hinzufügen
\draw[->] ($(stp.west)!0.5!(pc.east)$) -- ++(0,1cm) node[above] {Text};
Es reicht aus, den Mittelpunkt zu finden und am Ende Text hinzuzufügen.
