我需要包装节点的标签。Input \\ scripts但它不起作用。
\node[regular polygon, regular polygon sides=8, minimum width=3cm,draw,label=center:Input \\ Files] (reg2) at (12,0){};
答案1
考虑以下 MWE：
\documentclass{report}
\usepackage{tikz}
\usetikzlibrary{shapes.geometric}
\begin{document}
\tikzset{arrow/.style = {thick,->,>=stealth,}}
\tikzset{arrow2/.style = {thick,dotted,->,>=stealth,}}
\begin{tikzpicture}
\node[regular polygon, regular polygon sides=8, minimum width=3cm,draw, text width=1.2cm,align=center] (reg1) at (0,0){Input Scripts};
\node[circle,minimum size=3cm, draw, label=center:Export Files] (c1) at (6,0){};
\node[regular polygon, regular polygon sides=8, minimum width=3cm,draw,label=center:Input Files] (reg2) at (12,0){};
\node[regular polygon, regular polygon sides=4, minimum width=3cm,draw,label=center:Execute] (s1) at (6,-6){};
\draw[arrow] (reg1.east) -- (c1.west);
\draw[arrow] (c1.east) -- (reg2.west);
\draw[arrow] (reg1.east) -- (s1.north);
\draw[arrow] (reg2.west) -- (s1.north);
\end{tikzpicture}
\end{document}
结果如下：
