显示坐标而不是我想要的标签

Question

你好，我是硕士生，刚开始接触 LaTeX。我写了一个程序，可以在显示屏上显示坐标，而不是我想要的标签，就像这样显示。。

\documentclass[a4paper, oneside]{standalone}
\usepackage{tikz}


\begin{document}
    \begin{tikzpicture}



        \foreach  \Point/\PointLabel  in {(0,0), (-0.08,-0.75), (-0.22,-1.5), (-0.44,-2.25), (-1.01,-3.5), (-1.49,-4.25), (-2.09,-5), (-2.87,-5.75)/,}
        \draw[thick, fill=black] \Point circle (0.08) node[below right] {$\PointLabel$};


            \draw[thick, black] (0,0.4) arc (0:-52:8cm);


\end{tikzpicture}
\end{document}

仍然有问题，如果有配置问题，请帮助我

Answer 1

在 OP 的 MWE 中，没有提供标签，所以我将它们添加到\foreach数据列表中。

\documentclass[a4paper, oneside]{standalone}
\usepackage{tikz}


\begin{document}
    \begin{tikzpicture}



        \foreach  \Point/\PointLabel  in {(0,0)/B=P_n, (-0.08,-0.75)/P_{a=1},
         (-0.22,-1.5)/P_k, (-0.44,-2.25)/Q_k, (-1.01,-3.5)/P_{k-1},
         (-1.49,-4.25)/P_2, (-2.09,-5)/P_1, (-2.87,-5.75)/A=P_0,}
        \draw[thick, fill=black] \Point circle (0.08) node[below right] {$\PointLabel$};


            \draw[thick, black] (0,0.4) arc (0:-52:8cm);


\end{tikzpicture}
\end{document}
