CONTRACTED_By我正在尝试（但没有成功）使用以下方法来减少此 ER 模型中关系的大小tikz-er2包裹。它自然地将高度与宽度缩放，但我希望高度更短。有什么方法可以实现吗？（抱歉，这不是尽可能最小的，但我决定复制我拥有的图形。）
\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}

您可以aspect使用 键更改该节点的比例aspect。默认情况下，样式中它设置为1。这里我将其更改为2。
\documentclass[border=5pt]{standalone}
\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);
\node[attribute] (w2) [above right=1cm of worker,xshift=-1cm] {Name} edge (worker);
\node[attribute] (w3) [below left=1cm of worker,xshift=1cm] {Title} edge (worker);

\node[attribute] (wn2) [below=of worksin,yshift=0.5cm] {Duration} edge (worksin);
\node[entity] (project) [right=of worksin] {PROJECT} edge node[above left] {1} (worksin);

答案2
由于缺少 tikz-er2，我无法编译您的代码，但查看您的代码，由于文本长度，“CONTRACTED_BY”的框更大。我假设如果您减小文本的大小，框也会变小。您可以尝试以下操作：
\node[relationship] (contract) [below=of project] {\small CONTRACTED\_BY} edge node[above right] {N} (project);
