ER図の関係ノードのサイズ調整

私は、CONTRACTED_ByこのERモデルの関係の大きさを、tikz-er2パッケージ高さは幅に合わせて自然に拡大縮小されますが、高さをもっと短くしたいです。それを実現する方法はありますか? (申し訳ありませんが、これは最小限ではありませんが、私が持っている図を再現することにしました。)

\documentclass[12pt]{article}
\usepackage{tikz,tikz-er2}

\usetikzlibrary{positioning}
\begin{document}

\begin{tikzpicture}[node distance=1.5cm]
\tikzset={every entity/.style = {minimum width=1cm,minimum height=0.8cm, text width=1cm,inner sep=1pt},
every attribute/.style = {minimum width=1.2cm,minimum height=0.5cm, text width=1.2cm,inner sep=1pt},
every relationship/.style = {minimum width=1.2cm,minimum height=0.5cm, text width=1.2cm,inner sep=1pt},
every edge/.style = {link}
}

\node[entity] (worker) {WORKER};
\node[attribute] (w1) [above left=1cm of worker,xshift=1cm] {\uline{Number}} edge (worker);

aspectキーを使用して、そのノードの比率を変更できますaspect。スタイルではデフォルトで に設定されています1。ここでは に変更しました2。

every relationship/.style = {minimum width=1.2cm,minimum height=0.5cm, text width=1.2cm,inner sep=1pt},
every edge/.style = {link}

コードの出力

答え2

tikz-er2 がないのでコードをコンパイルできませんが、コードを見ると、テキストの長さのために「CONTRACTED_BY」のボックスが大きくなっています。テキストのサイズを小さくすると、ボックスも小さくなると思います。次の操作を試してください。

\node[relationship] (contract) [below=of project] {\small CONTRACTED\_BY} edge node[above right] {N} (project);
