尝试连接 tikz 中的节点

Question

我正在尝试构建网络结构（图表）。我使用以下命令：

\begin{figure}[h]
\begin{center}
\begin{tikzpicture}
\tikzstyle{block} = [rectangle, draw=blue, thick, fill=blue!20,
text width=5em, text centered, rounded corners]
\tikzstyle{line} = [draw, -latex’]
\tikzstyle{cloud} = [draw=red, thick, ellipse,fill=red!20, minimum height=8em];
\matrix [column sep=6mm,row sep=10mm]
{
% row 1
 & &
\node [block] (init) {Lack of information}; &
 \\
% row 2
& & & & & \\
% row 3
& &
\node [block] (identify) {Perceptions about Nato's presence}; & \\
% row 3
\node [block] (update) {Positive perceptions}; &
& & &
\node [block] (evaluate) {Negative perceptions}; & \\
% row 4
 \node [block] (decide) {Desirable presence}; &
& & &
\node [block] (evaluate) {Non-desirable presence}; & \\
% row 5
& & & & & \\
% row 6
\node [block] (stop) {Efficient presence}; & 
\node [block] (stop) {Useless presence}; &
\node [block] (stop) {Service to others’ interests}; &
\node [block] (stop) {No institutional role}; &
\node [block] (stop) {Inefficient presence}; &\\
};
%arrows
\end{tikzpicture}
\end{center}
\end{figure}

我的问题是我不知道如何用线连接我的一些节点。我尝试使用命令：\pathline--(); 但它不起作用。

什么是假的？

先感谢您

欢迎使用 TeX.SE！有几种绘制箭头的选项：

1. \draw[line] (init) -- (identify);line将从节点绘制一条样式线init来“识别”。
2. 或者，将从节点\draw (identify) edge[line] (update);绘制一条线样式来`更新。lineidentify
3. 如果您厌倦了总是指定样式，那么您可以使用在范围内绘制边缘every edge/.style={line}。
4. 为了能够绘制指向所有节点的箭头，您需要为它们赋予唯一的名称。但是，您命名了一堆节点stop。

以下是符合本网站惯例的代码：以 开头\documentclass，以 结尾\end{document}，可以编译。请考虑在将来发布此类文档。

\documentclass[tikz,border=3.14mm]{standalone}
\usetikzlibrary{matrix,arrows}

  text width=5em, text centered, rounded corners},
