我正在尝试绘制类似这样的图像:
但是,我只想将三个节点绘制为文本(“A”,“B”,“C”),带有双箭头和较大的重叠圆圈......
我在以下方面取得了一些成功:
\begin{tikzpicture}[->,>=stealth',shorten >=1pt,auto,node distance=2.8cm,semithick]
\tikzstyle{style}=[fill=white,draw=none,text=white]
\tikzstyle{line} = [draw, -latex']
\node[state] (A) {A};
\node[state] (B) [right of=A] {B};
\node[state] (C) [right of=B] {C};
\path [line, <->] (A) -- (B);
\path [line, <->] (B) -- (C);
\end{tikzpicture}
但是我无法得到重叠的外圆。它们应该重叠,使得围绕 A 的圆包含 B,围绕 B 的圆包含 A 和 C,而围绕 C 的圆包含 B。

也许 :
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{arrows,calc,through}
\begin{document}
\begin{tikzpicture}[->,>=stealth',shorten >=1pt,auto,node distance=2.8cm,semithick]
\tikzset{style/.style={fill=white,draw=none,text=white}}
\tikzset{line/.style = {draw, -latex'}}
\node (A) {A};
\node (B) [right of=A] {B};
\node (C) [right of=B] {C};
\node [draw] at (A) [circle through={($(B)+(1,1)$)}] {};
\node [draw] at (B) [circle through={($(A)-(1,1)$)}] {};
\node [draw] at (C) [circle through={($(B)-(1,1)$)}] {};
\path [line, <->] (A) -- (B);
\path [line, <->] (B) -- (C);
\end{tikzpicture}
\end{document}
