你应该看一下venndiagram
手动的。特别是radius
和overlap
键值选项,以及\setpostvennhook
带有其描述段落的命令。
\documentclass{article}
\usepackage{venndiagram}
\begin{document}
This:
\begin{venndiagram2sets}[overlap=-0.5cm,radius=0.8cm]
\node at ([shift={(-0.2cm,0.2cm)}] venn top left) {$\Omega$};
\end{venndiagram2sets}
Or this:
\begin{venndiagram2sets}[overlap=-0.5cm,radius=0.8cm,labelA={},labelB={}]
\node at ([shift={(-0.2cm,0.2cm)}] venn top left) {$\Omega$};
\setpostvennhook{
\node[below] at ([shift={(-0.3cm,-1.4cm)}] labelA) {$A$};
\node[below] at ([shift={(0.3cm,-1.4cm)}] labelB) {$B$};
}
\end{venndiagram2sets}
\end{document}
