我正在尝试在图表中的节点之间绘制箭头，如下图所示。圆弧不太好看，因为它们与我想要的半径不一致，而且我画的是虚线。非常感谢您的任何建议。
更新：我忘了说我还想在每个弧上方写一段文字。更新 2：新代码和结果位于本文末尾。

\begin{document}
\begin{tikzpicture}[auto, node distance = 30mm and 40mm,
dot/.style = {circle, fill=red, inner sep=2pt, node contents={}},

\draw[-latex,dashed] (5,0) arc[start angle=0, end angle=360,radius=5cm];

这是我根据以下答案编写的更新后的代码。
\documentclass[border=1cm]{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows.meta, automata,
calc,

\begin{document}
\begin{tikzpicture}[auto, node distance = 30mm and 40mm,

every edge/.style = {draw=blue, line width=1pt, -Stealth,
shorten >=2pt, shorten <=2pt,
},
every edge quotes/.style = {auto, sloped, inner sep=2pt},
every label/.style = {rectangle, inner sep=2pt, font=\large},
mincut/.style = {draw=green!40!black, line width=3pt, dashed}
]
\foreach [count=\i] \ang in {60}
{
\node[state] (5) at (0:5cm) {$5$};
\node[state] (4) at (60:5cm) {$4$};
\node[state] (1) at (120:5cm) {$1$};
\node[state] (2) at (180:5cm) {$2$};
\node[state] (3) at (240:5cm) {$3$};
\node[state] (6) at (300:5cm) {$6$};
}
;
\path (1) edge["text 7",near start] (6)
(3) edge["text 8", near start] (4);
% 1-4
\draw[{Stealth}-,line width=1pt, blue] (60*1+5:5cm) arc (60*1+5:60*1+55:5cm) node [pos=0.5, above, red, sloped] {text 2};
% 4-5
\draw[{Stealth}-,line width=1pt, blue] (60*6+5:5cm) arc (60*6+5:60*6+55:5cm) node [pos=0.5, above, red, sloped] {text 4};
% 5-6
\draw[{Stealth}-,line width=1pt, blue] (60*5+5:5cm) arc (60*5+5:60*5+55:5cm) node [pos=0.5, above, red, sloped] {text 5};
% 6-3
\draw[{Stealth}-,line width=1pt, blue] (60*4+5:5cm) arc (60*4+5:60*4+55:5cm) node [pos=0.5, above, red, sloped] {text 5};
% 1-2
\draw[-{Stealth},line width=1pt, blue] (60*2+5:5cm) arc (60*2+5:60*2+55:5cm) node [pos=0.5, above, red, sloped] {text 1};
% 2-3
\draw[-{Stealth},line width=1pt, blue] (60*3+5:5cm) arc (60*3+5:60*3+55:5cm) node [pos=0.5, above, red, sloped] {text 3};
\end{tikzpicture}
\end{document}
由此得到此图。
答案1
您可以使用它arc在节点之间绘制完美的曲线，但您应该提供一些偏移以免与节点重叠。
\documentclass[border=1cm]{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows.meta, automata, calc, positioning, quotes}
\begin{document}
\begin{tikzpicture}[auto, node distance = 30mm and 40mm,
dot/.style = {circle, fill=red, inner sep=2pt, node contents={}},
every state/.style = {circle, draw=red, very thick},
every edge/.style = {draw=blue, line width=1pt, -Stealth, shorten >=2pt, shorten <=2pt,},
every edge quotes/.style = {auto, sloped, inner sep=2pt},
every label/.style = {rectangle, inner sep=2pt, font=\large},
mincut/.style = {draw=green!40!black, line width=3pt, dashed}
]
\foreach [count=\i] \ang in {60} {
\node[state] (1) at (120:5cm) {$1$};
\node[state] (2) at (\ang+120:5cm) {$2$};
\node[state] (3) at (2*\ang+120:5cm) {$3$};
\node[state] (6) at (3*\ang+120:5cm) {$6$};
\node[state] (5) at (4*\ang+120:5cm) {$5$};
\node[state] (4) at (5*\ang+120:5cm) {$4$};
};
\foreach \i in {0,...,5}
\draw[{Stealth}-,line width=1pt] (60*\i+5:5cm) arc (60*\i+5:60*\i+55:5cm);
\end{tikzpicture}
\end{document}

没有专家解决方案：
\documentclass[border=1cm]{standalone}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\foreach \i in {1,...,6}{%
\draw[-latex,line width=2pt] (60*\i+5:5cm) arc (60*\i+5:60*\i+55:5cm);
\draw[red] (60*\i:5cm) circle(12pt);
\node at (60*\i:5cm) () {$\i$};
}
\filldraw (0,0) circle(2pt); % comment this line if you dont want the circle center
\end{tikzpicture}
\end{document}
