概述和调整矩阵

Question

请耐心等待，因为这是一个由多部分组成的问题。首先，我尝试弄清楚如何概述矩阵并且不改变矩阵中节点的样式。也许更好的问题是如何配置节点/矩阵而不改变其范围内的任何东西。

其次，我希望第二个/右矩阵的顶部与c.southpositioning我尝试使用via来实现这一点right = of c.south，但它会产生奇怪的重叠现象，并将锚点从节点原点更改为节点的西锚点。（蓝点是当前正在使用的锚点）

下面是我希望它最终呈现的样子，我通过使用right = of c.south east, anchor = north west选项强制mtrx2这样做，会将锚点推到错误的位置（我不想要）。那么有没有更好的方法来定位矩阵呢？

您可以使用距离来明确输入移位量，也可以使用来nodes={}覆盖常规选项。这就是matrix of nodes键很重要的原因。

\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{shapes, arrows, calc, positioning,matrix}

\tikzset{
state/.style={rounded rectangle, draw, text centered, minimum height=3em ,minimum width = 6em, inner sep = 5pt},
test/.style = {diamond, draw, shape aspect=2, inner sep = 0pt,text width = 7em,text centered},
action/.style ={rectangle, draw,text width=8em,inner sep = 3pt, minimum height=5em},
data/.style = {trapezium, draw, trapezium left angle=60, trapezium right angle=120pt, minimum height = 6em},
line/.style = {draw, -triangle 45},
list/.style = {rectangle, draw,minimum width = 6em},
ptr-box/.style = {rectangle, text width = 8em}
}

\begin{document}
\begin{tikzpicture}[font = \small]
    \matrix [matrix of nodes, column sep = 0.5em, row sep = 1.3em] (mtrx1)
    {  
    |[state]| a\\
    |[data]|  b\\
    |[test]|  c\\
    |[action]|d\\
    |[test]|  e\\
    |[action]|f\\
    |[action]|g\\
    }; 

    \matrix [matrix of nodes,column sep = 0.5em, row sep = 1.3em, 
    draw, dashed,
    nodes = {solid,red}, %<- Overrides
    right = 2cm of mtrx1-3-1.south, %How much further from right of the node...
    anchor = north west,
    ] (mtrx2)
    {
                    &|[state]| aa\\
                    &|[test]|  bb\\
                    &|[action]|cc\\
                    &|[data]|  dd\\
    |[state]|  ee   &|[state]| ff\\
    }; 

    % Draw edges
    \path [draw] (mtrx1-1-1) -- (mtrx1-7-1);    
    \path [draw] (mtrx2-1-2) -- (mtrx2-5-2);
\end{tikzpicture}
