我想要在菱形节点旁边添加两个标签。右边的一条写着“Ja”，位于道路上方，另一条写着“Nein”，位于道路旁边。目前看来创建了两个新节点。我认为我使用选项列表的方式不对。另一个问题是，我想要一个第一列和第二列之间的间隔更大这样路径就不会越过“]”符号。最后，我想改变节点之间的水平距离，这样整个图片就会更纤细。
标签现在位于菱形节点下方。

抱歉，当我粘贴代码时，它看起来和我之前组织的方式不一样。无论如何它都应该能工作。
答案1
- 为了改变第一列和第二列之间的距离，我将选项
[2mm]纳入了第二个单元格。 为了向路径添加标签，我在路径操作中包含了一个节点，例如：
\path (pap-9-2)--(pap-10-2) **node [near start, right] {Your Text here};
这会在near start路径的右侧添加一个节点，连接第 2 列的第 9 个和第 10 个单元格。
- 为了改变距离，我去掉了列，这样最后就只剩下两列了，而且我能够在操作中设置第一列和第二列之间的距离
every matrix/.style。此外，我在一个单元格中添加了两个节点，例如：
...
\usetikzlibrary{...,定位,...}
...
\begin{tikzpicture}[每个矩阵/.style ={column sep=2mm}]
...
\matrix (矩阵名称) {
...
& \node (produktion) [操作] {Produktion}; \node (wartung) [operation,right=3mm of produktion] {Wartung}; \\\\}；
...
以下是一个例子：
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{positioning,arrows,matrix}
\begin{document}
\begin{tikzpicture}[
every matrix/.style={matrix of nodes,nodes in empty cells,column sep=1cm,row sep=1cm},
every node/.style ={text centered,anchor=center},
arrow/.style ={draw,->},
line/.style ={draw,dashed}]
\matrix (matrix)
{
& |[draw]| {Cell 1-2}\\
Cell 2-1] & \node (A) [draw,anchor=east,xshift=-2mm,text width=2cm] {Node A in Cell 2-2}; \node (B) [draw,right=2mm of A,,text width=2cm] {Node B in Cell 2-2};\\
& |[draw]| {Cell 3-2}\\
};
\begin{scope} [every path/.style=arrow]
\path (matrix-1-2)-| (A) node [near start,below] {1};
\path (matrix-1-2)-| (B) node [near start,below] {2};
\path (A) |- (matrix-3-2) node [near end,above]{3};
\path (B) |- (matrix-3-2) node [near end,above]{4};
\path (matrix-3-2)-- ([yshift=-2mm]matrix-3-2.south)-|([xshift=-2mm]A.west)|-([yshift=2mm]matrix-1-2.north) --(matrix-1-2) node [near end,above=2mm] {5};
\end{scope}
\begin{scope} [every path/.style=line]
\path(matrix-2-1)--(A);
\end{scope}
\end{tikzpicture}
\end{document}
它看起来是这样的：
