Tikz Matrix hat große Lücken zwischen den Zeilen

Question

Ich habe ein Problem, bei dem die Matrix, die ich einfüge, extrem große Lücken zwischen den Zeilen aufweist. Aus irgendeinem Grund beträgt die Lücke zwischen jeder Zeile etwa 10,5 cm, und ich kann nicht herausfinden, warum. Der folgende Code erstellt dieses Bild, wobei die Oberseite der Matrixbox über die Seite hinausragt. Wie man sehen kann, besteht zwischen den Aufgabenknoten „Legende“ und „Moderator“ eine beträchtliche Lücke.

Ich bin derzeit neu bei Latex und lerne aus einer Reihe unterschiedlicher Quellen und Tutorials, daher ist mein Code möglicherweise nicht sinnvoll.

Willkommen! Die Knoten in der Matrix haben die Schlüssel on chainund on grid, die sie von erben base. Sie müssen diese Schlüssel löschen.
