tikz 中带边的箭头

我有一个用于概念模型的 tikz 图。我试图从上下文因素到输入绘制一个有边的箭头。不知道该怎么做

\begin{figure}[h]

comment/.style={rectangle, inner sep= 5pt, text width=4cm, node distance=0.25cm, font=\scriptsize\sffamily},
% The force style is used to draw the forces' name
force/.style={rectangle, draw, fill=black!10, inner sep=5pt, text width=4cm, text badly centered, minimum height=1.2cm, font=\bfseries\footnotesize\sffamily}]

\path[->,thick] 
(state) edge (input)
(state) edge (organization)
(state) edge  (output)
(external) edge (output)
(input) edge (organization)
(organization) edge (output);

答案1

类似于此。由于内部名称 (external) 和 (input) 已定义，因此只需将以下几行（从 到 连接west of external）添加north of input到代码的最后一行即可。

 \draw [->,thick] (external.west) -| (input.north);

在此处输入图片描述

代码

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{calc,arrows,positioning}

\tikzstyle{vertex}=[circle,draw,minimum size=1cm]
\tikzstyle{every node}=[vertex]
