如何使用 tikz 调整节点中部分文本的大小？

我有一张图表，其中节点上方的时间是出发时间。我如何才能更好地格式化“+1”？它代表“第二天”。现在相对于时间来说太大了，而且“加号”也太夸张了。我试图把“+1”弄小一点，也许用不同的颜色。

我该如何实现这个？谢谢！

编辑：我怎样才能减少覆盖每个边缘的白色部分？（边缘中间被数字覆盖的部分）

我会稍微重新设计一下你的形象。我建议使用：

  • quotes边缘标签库
  • 在节点 O、A、H、E 和 D 使用labels时间信息
  • 大多数样式写为选项tikzpicture：

every edge quotes/.style = {font=\scriptsize, text=black, fill=white, inner sep=2pt}
                        ]
\node (O) [C=red!30, 
           label=below:\clock{18}{15}\\\scriptsize{18:15}]  {$\mathcal{O}$};

我可能一开始就读错了，你只想调整 +1 的大小。一种方法是向节点添加一个标签，其中包含 +1 并正确定位。我试过这个（注意每个节点的样式）：

\begin{scope}[font=\tiny,every node/.style={inner sep=0pt}]
            \node [above=0.5pt of A] {\clock{15}{30} 15:30};
            \node [below=0.5pt of Orig] {\clock{18}{15} 18:15};
            \node [above=0.5pt of H,label={[scale=0.7]10:$+1$}] {\clock{8}{30} 8:30};

这就导致了：

不同的标签

您可以看到节点 H（带标签）和节点 E（旧样式）之间的区别。以下是完整代码，其中到达也作为节点标签：

不相关，但是您的代码可以改进得更短，您不需要所有这些scope。

答案3

在此处输入图片描述

我使用\scalebox命令来缩小+1。

通过设置来控制箭头标签周围的空白inner sep。

此外，我以一种对我来说更自然的方式重写了您的代码，没有所有的scopes。使用\foreach是一种设置坐标和边缘的简单方法，以防您想要添加或更改任何内容。

以下是代码：

\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{positioning}

\usepackage{clock}

\ClockFrametrue\ClockStyle=0

\newcommand{\orig}{\ensuremath{\mathcal{O}}} % origin position
\newcommand{\dest}{\ensuremath{\mathcal{D}}} % destination position

\tikzset{vertex/.style={circle, thick, inner sep=0mm, minimum width=7mm, draw}}

\begin{document}

\begin{tikzpicture}
\node[vertex, fill=red!30] (Orig) at (0,0) {$\orig$};
\node[vertex, fill=green!30] (Dest) at (8,1) {$\dest$};
\foreach \x/\y/\nm/\lbl in {2/2/A/A,2.3/.5/B/B,3.3/-1.2/C/C,4.2/2.1/H/H,6.4/-.5/L/L,5.9/1.9/E/E} 
    \node[vertex](\nm) at (\x,\y) {\lbl};
\foreach \a\b\lbl in {Orig/B/5,Orig/C/5,B/C/3,B/H/3,B/L/3,C/L/5,E/L/8,L/Dest/8}
    \draw [very thick,-stealth](\a)--(\b) node[circle, fill=white, inner sep=.5mm, midway]{\lbl};
\foreach \a\b\lbl in {Orig/A/5,A/H/5,H/E/3,E/Dest/8}
    \draw [draw=red, fill=black, very thick, arrows={-stealth[black]}](\a)--(\b) node[circle, fill=white, inner sep=.5mm, midway]{\lbl};
\foreach \n\hr\min\day in {A/15/30/,Orig/18/15/,H/8/30/+1,E/10/45/+1,Dest/12/00/+1}
    \node [font=\tiny, above=0.5pt of \n] {\clock{\hr}{\min} \hr:\min${}^{\scalebox{.8}{\day}}$};
