与图片的其余部分相比，节点字体大小很大

Question

如何调整节点 (h) 的字体大小，使其与图片的其余部分相比具有 "reasonable" 大小？我不得不使用 \fontsize 非常小的数字，但仍然不够！

\begin{figure}[!htbp]
    \begin{center}

    \begin{tikzpicture}[>=latex,scale=4, every node/.style={transform shape}]

    \foreach \x/\y in {-0.8368/0.3636,-0.9218/0.267,-0.9721/0.1317,-0.9218/-0.1775,-0.8098/-0.3128}
    { \draw[thick] (\x,\y) -- (-0.5968,0);}

    \foreach \x/\y in {0.7247/-0.3244,0.8368/-0.2316,0.9103/-0.05771,0.9141/0.1394,0.8136/0.3559}
    { \draw[thick] (\x,\y) -- (0.5968,0);}

    \draw[thick] (-0.5968,0.) -- (0.5968,0.) node(h)[pos = 0.25,above]{\fontsize{0.001cm}{0.01cm}\selectfont $S_I^2$} node(i)[pos = 0.75]{};

    \filldraw[gray] (-0.5968,0.) circle (0.2);
    \filldraw[gray] (0.5968,0.) circle (0.2);

    \filldraw[white] (0,0.) circle (0.2);
    \draw[thick] (0,0.) circle (0.2);

    \end{tikzpicture}


    \end{center}
\end{figure}

Answer 1

您可以使用特定于节点的缩放属性（参见 scale=0.35）：

\begin{figure}[!htbp]
  \begin{center}
    \begin{tikzpicture}[>=latex,scale=4, every node/.style={transform shape}]
      \foreach \x/\y in {-0.8368/0.3636,-0.9218/0.267,-0.9721/0.1317,-0.9218/-0.1775,-0.8098/-0.3128}
      { \draw[thick] (\x,\y) -- (-0.5968,0);}
      \foreach \x/\y in {0.7247/-0.3244,0.8368/-0.2316,0.9103/-0.05771,0.9141/0.1394,0.8136/0.3559}
      { \draw[thick] (\x,\y) -- (0.5968,0);}
      \draw[thick] (-0.5968,0.) -- (0.5968,0.) node(h)[pos = 0.25,above,scale=0.35]{\fontsize{0.001cm}{0.01cm}\selectfont $S_I^2$} node(i)[pos = 0.75]{};
      \filldraw[gray] (-0.5968,0.) circle (0.2);
      \filldraw[gray] (0.5968,0.) circle (0.2);
      \filldraw[white] (0,0.) circle (0.2);
      \draw[thick] (0,0.) circle (0.2);
    \end{tikzpicture}
  \end{center}
\end{figure}

与图片的其余部分相比，节点字体大小很大

Node font size is huge compared to the rest of the picture
