![如何更改 TikZ 图表中的标签距离](https://linux22.com/image/316122/%E5%A6%82%E4%BD%95%E6%9B%B4%E6%94%B9%20TikZ%20%E5%9B%BE%E8%A1%A8%E4%B8%AD%E7%9A%84%E6%A0%87%E7%AD%BE%E8%B7%9D%E7%A6%BB.png)
就 TikZ 而言,我完全是一个初学者,所以请原谅我的一些愚蠢行为。
我想用 TikZ 制作一个字段塔,但是内部标签和边缘的距离太大。我想减少这个距离。有没有一种简单的方法可以实现这一点,而不需要重写整个代码?我之前搜索过答案,但我发现的所有问题要么略有不同,要么答案变得非常复杂(至少对我来说)。
这是一个最小工作示例:
\documentclass[a4paper,12pt]{scrartcl}
\usepackage[utf8]{inputenc} % input encoding
\usepackage[T1]{fontenc} % use T1 fonts for font encoding
\usepackage{amsfonts} % math font
\usepackage{tikz}
\newcommand{\Fr}{\textbf{F}}
\newcommand{\F}{\mathbb{F}}
\begin{document}
\begin{center}
\begin{tikzpicture}[node distance = 2cm, auto]
\node (F3) {$\F_3$};
\node (F33) [above of=F3, left of=F3] {$\F_{3^3}$};
\node (F32) [above of=F3, right of=F3] {$\F_{3^2}$};
\node (F36) [above of=F3, node distance = 4cm] {$\F_{3^6}$};
\node (F318)[above of=F33, node distance = 4cm] {$\F_{3^{18}}$};
\node (F39) [above of=F33, left of=F33] {$\F_{3^9}$};
\draw[-] (F3) to node {3} (F33);
\draw[-] (F3) to node [swap] {2} (F32);
\draw[-] (F32) to node [swap] {3} (F36);
\draw[-] (F33) to node {2} (F36);
\draw[-] (F33) to node {3} (F39);
\draw[-] (F36) to node [swap] {3} (F318);
\draw[-] (F39) to node {2} (F318);
\draw (F3) to node [swap] {$\langle \Fr \rangle$} (F33);
\draw (F3) to node {$\langle \Fr \rangle$} (F32);
\draw (F32) to node {$\langle \Fr^2 \rangle$}(F36);
\draw (F33) to node [swap] {$\langle \Fr^3\rangle$} (F39);
\draw (F33) to node [swap] {$\langle \Fr^3\rangle$} (F36);
\draw (F36) to node {$\langle \Fr^6\rangle$} (F318);
\draw (F39) to node [swap] {$\langle \Fr^9\rangle$} (F318);
\end{tikzpicture}
\end{center}
\end{document}

笨拙的解决方案:
\documentclass[a4paper,12pt]{scrartcl}
\usepackage[utf8]{inputenc} % input encoding
\usepackage[T1]{fontenc} % use T1 fonts for font encoding
\usepackage{amsfonts} % math font
\usepackage{tikz}
\newcommand{\Fr}{\textbf{F}}
\newcommand{\F}{\mathbb{F}}
\begin{document}
\begin{center}
\begin{tikzpicture}[
node distance = 2cm, auto,
every node/.style = {inner sep=1pt,outer sep=0pt},
vrtc/.style = {inner sep=3pt}]
\node (F3) [vrtc] {$\F_3$};
\node (F33) [vrtc,above of=F3, left of=F3] {$\F_{3^3}$};
\node (F32) [vrtc,above of=F3, right of=F3] {$\F_{3^2}$};
\node (F36) [vrtc,above of=F3, node distance = 4cm] {$\F_{3^6}$};
\node (F318)[vrtc,above of=F33, node distance = 4cm] {$\F_{3^{18}}$};
\node (F39) [vrtc,above of=F33, left of=F33] {$\F_{3^9}$};
\draw[-] (F3) to node {3} (F33);
\draw[-] (F3) to node [swap] {2} (F32);
\draw[-] (F32) to node [swap] {3} (F36);
\draw[-] (F33) to node {2} (F36);
\draw[-] (F33) to node {3} (F39);
\draw[-] (F36) to node [swap] {3} (F318);
\draw[-] (F39) to node {2} (F318);
\draw (F3) to node [swap] {$\langle \Fr \rangle$} (F33);
\draw (F3) to node {$\langle \Fr \rangle$} (F32);
\draw (F32) to node {$\langle \Fr^2 \rangle$}(F36);
\draw (F33) to node [swap] {$\langle \Fr^3\rangle$} (F39);
\draw (F33) to node [swap] {$\langle \Fr^3\rangle$} (F36);
\draw (F36) to node {$\langle \Fr^6\rangle$} (F318);
\draw (F39) to node [swap] {$\langle \Fr^9\rangle$} (F318);
\end{tikzpicture}
\end{center}
\end{document}
在上面的代码中,我将所有节点的内部分离减少到 1pt 并定义节点vrtc
,然后将其返回到 3pt。
