Ich versuche (erfolglos), die Größe der CONTRACTED_ByBeziehung in diesem ER-Modell zu reduzieren, indem ichtikz-er2Paket. Die Höhe skaliert natürlich mit der Breite, aber ich hätte lieber eine geringere Höhe. Gibt es eine Möglichkeit, das zu erreichen? (Tut mir leid, das ist nicht so minimal, wie es sein könnte, aber ich habe mich entschieden, die Figur, die ich habe, nachzubilden.)

Antwort1
aspectSie können das Verhältnis dieses Knotens mit der Taste ändern aspect. Standardmäßig ist es im Stil auf eingestellt 1. Hier habe ich es auf geändert 2.

Antwort2
Ich kann Ihren Code nicht kompilieren, da mir tikz-er2 fehlt, aber wenn ich mir Ihren Code ansehe, ist das Feld „CONTRACTED_BY“ aufgrund der Textlänge größer. Ich nehme an, wenn Sie die Textgröße reduzieren, wäre das Feld auch kleiner. Sie können Folgendes versuchen:
\node[relationship] (contract) [below=of project] {\small CONTRACTED\_BY} edge node[above right] {N} (project);
