如图所示,我已经有三个节点和相互连接的箭头。箭头形成一个循环,我想在三角形区域内添加一个带箭头的圆圈(可能带有文本)以指示形成了一个循环。我该怎么做?
我已经拥有的代码:
\documentclass[border={10pt 10pt 10pt 10pt}]{standalone}
\usepackage{tikz}
\usetikzlibrary{shapes, positioning, arrows.meta, decorations.pathmorphing}
\begin{document}
\begin{tikzpicture}[
node distance = 3.0cm and 1.5cm,
sa/.style = {->, thick},
sb/.style = {->, thick, dashed, red},
sc/.style = {->, thick, dotted, blue},
n/.style = {draw, inner sep = 3pt, align = center}]
\node[n] (ta)
{Content};
\node[n, left = of ta] (tb)
{Content};
\node[n, below right = of tb] (tc)
{Content};
\draw[sa, sloped] (ta) to (tb);
\draw[sb] (tb) to (tc);
\draw[sc] (tc) to (ta);
\end{tikzpicture}
\end{document}

作为一个快速技巧,你可以手动添加弧和文本:
\documentclass[border={10pt 10pt 10pt 10pt}]{standalone}
\usepackage{tikz}
\usetikzlibrary{shapes, positioning, arrows.meta, decorations.pathmorphing}
\begin{document}
\begin{tikzpicture}[
node distance = 3.0cm and 1.5cm,
sa/.style = {->, thick},
sb/.style = {->, thick, dashed, red},
sc/.style = {->, thick, dotted, blue},
n/.style = {draw, inner sep = 3pt, align = center}]
\node[n] (ta)
{Content};
\node[n, left = of ta] (tb)
{Content};
\node[n, below right = of tb] (tc)
{Content};
\draw[sa, sloped] (ta) to (tb);
\draw[sb] (tb) to (tc);
\draw[sc] (tc) to (ta);
\draw[->,red] (-0.4,-1) arc [radius=0.5cm,start angle=0,end angle=340];
\node at (-0.4-0.5,-1) {Text};
\end{tikzpicture}
\end{document}
