如何在两个节点之间移动边

Question

(a4) edge [line width=7pt] (a10)我想问一下如何才能将这张图片中的分隔线向上移动：

\documentclass[border=1mm,tikz]{standalone}
\usetikzlibrary{arrows,automata,shapes.multipart,calc,decorations.text}
\begin{document}

    \begin{tikzpicture}[-,>=stealth',shorten >=1pt,auto,node distance=4cm,semithick,
        every text node part/.style={align=center},
        %,inner sep=0pt
        %,scale=0.5
        ]
      % \tikzstyle{every state}=[fill=blue!25,text=black,draw=none]

      \node[](a1)   {};
      \node[state,minimum size=1cm](a2) [right of=a1] {\Large$3$};
      \node[](a3) [right of=a2] {};
      \node[](a4) [above of=a2] {};
      \node[](a5) [above of=a4] {};
      \node[](a10) [above of=a5] {};
      \node[state,minimum size=1cm](a6) [left of=a5] {\Large$2$};
      \node[state,minimum size=1cm](a7) [above of=a6] {\Large$1$};
      %
      \node[state,minimum size=1cm](a8) [right of=a5] {\Large$4$};
      \node[state,minimum size=1cm](a9) [above of=a8] {\Large$5$};


    \begin{scope}[every node/.style={scale=1.5}] 
        \path (a7)  edge [sloped, anchor=center,above] node {31.6 m} (a2)
              (a6)  edge [sloped, anchor=center,above] node {22.36 m} (a2)
              (a8)  edge [sloped, anchor=center,above] node {22.36 m} (a2)
              (a9)  edge [sloped, anchor=center,above] node {31.6 m} (a2)
              (a6)  edge [sloped, anchor=center,above] node {10 m} (a7)
              (a8)  edge [sloped, anchor=center,above] node {10 m} (a9)
              (a4)  edge [line width=7pt] (a10)
              ;


    \end{scope}
    \end{tikzpicture}

\end{document}

不改变节点的相对位置。该线(a4) edge [line width=7pt] (a10)表示标记为 1、2 和 4、5 的节点对之间的无线信号屏障。

我想设置节点 a4 和 a10 的 yshift，而不改变其余节点的位置。

问候

仅从看你的照片我怀疑你想要类似的东西(a6.south-|a2) edge [line width=7pt] (a7.north-|a2)。

\documentclass[border=1mm,tikz]{standalone}
\usetikzlibrary{arrows,automata}
\begin{document}

    \begin{tikzpicture}[-,>=stealth',shorten >=1pt,auto,node distance=4cm,semithick,
        every text node part/.style={align=center},
        ]

      \node[](a1)   {};
      \node[state,minimum size=1cm](a2) [right of=a1] {\Large$3$};
      \node[](a3) [right of=a2] {};
      \node[](a4) [above of=a2] {};
      \node[](a5) [above of=a4] {};
      \node[](a10) [above of=a5] {};
      \node[state,minimum size=1cm](a6) [left of=a5] {\Large$2$};
      \node[state,minimum size=1cm](a7) [above of=a6] {\Large$1$};
      %
      \node[state,minimum size=1cm](a8) [right of=a5] {\Large$4$};
      \node[state,minimum size=1cm](a9) [above of=a8] {\Large$5$};


    \begin{scope}[every node/.style={scale=1.5}] 
        \path (a7)  edge [sloped, anchor=center,above] node {31.6 m} (a2)
              (a6)  edge [sloped, anchor=center,above] node {22.36 m} (a2)
              (a8)  edge [sloped, anchor=center,above] node {22.36 m} (a2)
              (a9)  edge [sloped, anchor=center,above] node {31.6 m} (a2)
              (a6)  edge [sloped, anchor=center,above] node {10 m} (a7)
              (a8)  edge [sloped, anchor=center,above] node {10 m} (a9)
              (a6.south-|a2)  edge [line width=7pt] (a7.north-|a2)
              ;


    \end{scope}
    \end{tikzpicture}

\end{document}

当然，你可以进一步调整，例如([yshift=-5mm]a6.south-|a2) edge [line width=7pt] (a7.north-|a2)收益率

请注意，您定义的节点并非都是必需的。我建议使用positioning和根据节点的内容命名节点，这将引导我们：

\documentclass[border=1mm,tikz]{standalone}
\usetikzlibrary{arrows,automata,positioning}
\begin{document}

    \begin{tikzpicture}[-,>=stealth',shorten >=1pt,auto,
    node distance=3.5cm and 3.5cm,semithick,
        every text node part/.style={align=center},
        ]

      \node[state,minimum size=1cm](a3){\Large$3$};
      \node[state,minimum size=1cm](a2) [above left=7cm and 3.5cm of a3] {\Large$2$};
      \node[state,minimum size=1cm](a1) [above=of a2] {\Large$1$};
      %
      \node[state,minimum size=1cm](a4) [above right=7cm and 3.5cm of a3] {\Large$4$};
      \node[state,minimum size=1cm](a5) [above=of a4] {\Large$15$};


    \begin{scope}[every node/.style={scale=1.5}] 
        \path (a1)  edge [sloped, anchor=center,above] node {31.6 m} (a3)
              (a2)  edge [sloped, anchor=center,above] node {22.36 m} (a3)
              (a4)  edge [sloped, anchor=center,above] node {22.36 m} (a3)
              (a5)  edge [sloped, anchor=center,above] node {31.6 m} (a3)
              (a2)  edge [sloped, anchor=center,above] node {10 m} (a1)
              (a4)  edge [sloped, anchor=center,above] node {10 m} (a5)
              ([yshift=-5mm]a2.south-|a3)  edge [line width=7pt] (a1.north-|a3)
              ;


    \end{scope}
    \end{tikzpicture}

\end{document}
