为什么形状会转移离子旋转？

我想用 tikz 画一幅类似的画 在此处输入图片描述

到目前为止创建了一个自定义形状

我开始画一幅类似上面的画

\documentclass{article}

\usepackage{tikz}
\usepackage{wesys}
\usetikzlibrary{positioning}
\makeatletter


\makeatother

\begin{document}
\begin{tikzpicture}
    \node[ windturbine, draw=black,dashed, minimum width=3cm, rotate=-10, xshift=5cm](turbineirot) {};
    \node[ windturbine, draw=black, fill=black, rotate=-40, xshift=5cm, minimum width=3cm,label={[midway,above]i}](turbinei) {};    

    \node[ windturbine, below=2cm of turbinei,rotate=-10, draw=black, fill=black, minimum width=3cm,label={[below= of turbinej, xshift=-8pt]j}](turbinej) {};

    \draw[-] (turbinei.center) -- (turbinej.center)node [midway,right,draw=none] {};
\end{tikzpicture}
\end{document}

当我旋转形状时，所有形状都会发生偏移，如何防止偏移？如何用标签绘制线条和用标签绘制角度？

答案1

这里问题的根源是xshift参数。您的形状并不完美（正如@JohnKormylo 在评论中提到的那样），但可以通过这种方式修复此问题（如果这是所需的输出）。

附言：您确实不需要那里的\makeatletter和\makeatother命令。

PS：你可能会注意到这里使用 filecontents 环境来创建单部分 MWE
