如何使用 Tikz 获得正确的 -| 键图箭头？

Question

-|当我尝试在 Tikzpicture 中使用或|-与 Bond Graph 箭头（f_out或）绘制路径时，e_out我得到了这个（红色圆圈显示箭头末端的错误位置）：

我更喜欢这样：

这里是 MWE：

\documentclass{article}
\usepackage{tikz}
\usepackage{bondgraphs}
\usetikzlibrary{calc}

\begin{document}%
\begin{tikzpicture}%
\node (node1) [draw, text width=5em, minimum height=8em] {node1};%
\path (node1.east)+(3,0) node (node2) [draw, text width=3em, minimum height=3em] {node2};%
\draw [bond, e_out] ( $ (node1.north east)!0.15!(node1.east) $ ) -| node [above, pos=0.2] {label1} (node2.north);%
\draw [bond, f_out]  (node2.south)  |- node [below, pos=0.8] {label2}  ( $ (node1.south east)!0.15!(node1.east) $ );%
\end{tikzpicture}%
\end{document}

有人能帮我解决这个问题吗？

Answer 1

看起来bondgraph不能正确处理使用-|或绘制的路径|-。我能提供的最简单的解决方案

1. 使用no bond样式在您不想要的部分获得相同的厚度bond。

2. 将路径分成两个部分，并no_bond在第一个和bond第二个部分使用：

   \draw [no bond, f_out] (node2.south) -- (X);
   \draw [bond] (X) -- (Y);
   

   其中(X)和(Y)是中间点。

代码：

\documentclass{article}
\usepackage{tikz}
\usepackage{bondgraphs}
\usetikzlibrary{calc}

\tikzset{no bond/.style={thick}}% <-- to get similar appearange

\begin{document}%
\begin{tikzpicture}%
    \node (node1) [draw, text width=5em, minimum height=8em] {node1};%
    \path (node1.east)+(3,0) node (node2) [draw, text width=3em, minimum height=3em] {node2};%
    
    \draw [no bond, e_out] ( $ (node1.north east)!0.15!(node1.east) $ ) -| node [above, pos=0.2] {label1} (node2.north);% <-- changed style
    %\draw [bond, f_out]  (node2.south)  |- node [below, pos=0.8] {label2}  ( $ (node1.south east)!0.15!(node1.east) $ );%
    \coordinate (Y) at ($(node1.south east)!0.15!(node1.east)$);
    \coordinate (X) at ($(node2.south)!(Y)!(node2.south)$);
    \draw [no bond, f_out] (node2.south) -- (X);
    \draw [bond] (X) -- (Y);
\end{tikzpicture}
\end{document}
