为 tikz 图表添加图例

Question

我正在通过包创建图片tikz。它在两个不同的帧上显示了一个八辐马车轮。我如何添加图例 __ 帧 1 和 ....帧 2？当我尝试使用\addlegendentry它时，它给我一个错误。提前致谢

 \documentclass[10pt,a4paper]{report}
 \usepackage{tikz}

 \begin{document}
   \begin{tikzpicture}[scale=3]
   \draw (0,0) circle (1cm);

   \draw (0:1cm) -- (180:1cm);
   \draw (45:1cm) -- (225:1cm);
   \draw (90:1cm) -- (270:1cm);
   \draw (135:1cm) -- (315:1cm);

   \draw[dotted] (7.5:1cm) -- (187.5:1cm);
   \draw[dotted] (52.5:1cm) -- (232.5:1cm);
   \draw[dotted] (97.5:1cm) -- (277.5:1cm);
   \draw[dotted] (142.5:1cm) -- (322.5:1cm);
   \end{tikzpicture}
 \end{document}

像这样？

您的问题不是很清楚，所以这只能作为起点...给出上图的 MWE 是：

\documentclass[10pt,a4paper]{report}
\usepackage{tikz}
\usetikzlibrary{positioning}

\begin{document}
    \begin{tikzpicture}[scale=3]
\node (n1) [circle,draw,minimum size=6cm] {};% node size can not be scaled
\node (n2) [draw,right=of n1,align=left] {- - - frame 1 \dots\\
                                          -----frame 2 \dots};  
\draw   (  0:1) -- (180:1)
        ( 45:1) -- (225:1)
        ( 90:1) -- (270:1)
        (135:1) -- (315:1);
\draw[dotted] 
        (  7.5:1) -- (187.5:1)
        ( 52.5:1) -- (232.5:1)
        ( 97.5:1) -- (277.5:1)
        (142.5:1) -- (322.5:1);
    \end{tikzpicture}
\end{document}
