Tikz 绘制不均匀的节点大小？

在下面的代码中，最后一个节点 (10) 在渲染时比其他节点大。我该如何阻止这种情况发生？

\usetikzlibrary{shapes.geometric}
\begin{tikzpicture}
[every node/.style={inner sep=0pt}]
[every node/.minimum size=2cm]
\node (1) [circle, fill=black, draw=black] at (87.5pt, -150.0pt) {\textcolor{black}{1}};
\node (2) [circle, fill=black, draw=black] at (112.5pt, -137.5pt) {\textcolor{black}{2}};
\node (3) [circle, fill=black, draw=black] at (137.5pt, -137.5pt) {\textcolor{black}{3}};
\node (4) [circle, fill=black, draw=black] at (112.5pt, -162.5pt) {\textcolor{black}{4}};
\node (5) [circle, fill=black, draw=black] at (137.5pt, -162.5pt) {\textcolor{black}{5}};
\node (6) [circle, fill=black, draw=black] at (162.5pt, -137.5pt) {\textcolor{black}{6}};
\node (7) [circle, fill=black, draw=black] at (162.5pt, -162.5pt) {\textcolor{black}{7}};
\node (8) [circle, fill=black, draw=black] at (187.5pt, -137.5pt) {\textcolor{black}{8}};
\node (9) [circle, fill=black, draw=black] at (187.5pt, -162.5pt) {\textcolor{black}{9}};
\node (10) [circle, fill=black, draw=black] at (212.5pt, -150.0pt) {\textcolor{black}{10}};
\draw [line width=0.625, color=black] (1) to  (2);
\draw [line width=0.625, color=black] (1) to  (4);
\draw [line width=0.625, color=black] (4) to  (5);
\draw [line width=0.625, color=black] (2) to  (3);
\draw [line width=0.625, color=black] (4) to  (2);
\draw [line width=0.625, color=black] (5) to  (3);
\draw [line width=0.625, color=black] (3) to  (6);
\draw [line width=0.625, color=black] (5) to  (7);
\draw [line width=0.625, color=black] (8) to  (6);
\draw [line width=0.625, color=black] (7) to  (9);
\draw [line width=0.625, color=black] (8) to  (10);
\draw [line width=0.625, color=black] (9) to  (10);
\draw [line width=0.625, color=black] (7) to  (6);
\draw [line width=0.625, color=black] (9) to  (8);
\end{tikzpicture}

答案1

使inner sep您选择的某个东西非零并从末尾删除数字。{10}在节点中写入 10，但由于您正在填充它，因此没有必要写入它们。然后初始正常括号例如，(10)设置标签。

答案2

例如使用[every node/.style={inner sep=0pt,minimum size=1.2em}]。如果数字不可见，那么添加数字有什么意义呢？

\begin{tikzpicture}[every node/.style={inner sep=0pt,minimum size=1.2em},
    ball/.style={circle, fill=black, draw=black},
    line/.style={line width=0.625, color=black},
    ]
\node (1)  [ball] at (87.5pt, -150.0pt) {\textcolor{black}{1}};
\node (2)  [ball] at (112.5pt, -137.5pt) {\textcolor{black}{2}};
\node (3)  [ball] at (137.5pt, -137.5pt) {\textcolor{black}{3}};
\node (4)  [ball] at (112.5pt, -162.5pt) {\textcolor{black}{4}};
\node (5)  [ball] at (137.5pt, -162.5pt) {\textcolor{black}{5}};
\node (6)  [ball] at (162.5pt, -137.5pt) {\textcolor{black}{6}};
\node (7)  [ball] at (162.5pt, -162.5pt) {\textcolor{black}{7}};
\node (8)  [ball] at (187.5pt, -137.5pt) {\textcolor{black}{8}};
\node (9)  [ball] at (187.5pt, -162.5pt) {\textcolor{black}{9}};
\node (10) [ball] at (212.5pt, -150.0pt) {\textcolor{black}{10}};
\draw [line] (1) to  (2);
\draw [line] (1) to  (4);
\draw [line] (4) to  (5);
\draw [line] (2) to  (3);
\draw [line] (4) to  (2);
\draw [line] (5) to  (3);
\draw [line] (3) to  (6);
\draw [line] (5) to  (7);
\draw [line] (8) to  (6);
\draw [line] (7) to  (9);
\draw [line] (8) to  (10);
\draw [line] (9) to  (10);
\draw [line] (7) to  (6);
\draw [line] (9) to  (8);
\end{tikzpicture}

使用明显更短的代码即可轻松获得相同的输出：

\begin{tikzpicture}[ball/.style={circle, draw, fill, inner sep=0pt, minimum size=1.2em}]
\draw [line width=0.625] (0,0) grid (3,1);
\foreach \x in {0,1,...,3}
  \path (\x,0) node [ball](\x0){} (\x,1) node [ball](\x1){};
\path (-1,.5) node[ball](left){} (4,.5) node[ball](right){};
\draw [line width=0.625] (left)--(00) (left)--(01) (right)--(30) (right)--(31);
\end{tikzpicture}

答案3

我以“自由”来扩展我的评论以进行回答。出于演示目的，我将可见的节点内容涂成白色（我想知道为什么在节点中放置数字，然后使用黑色填充覆盖？）同时使您的 MWE 更加简洁：

\begin{tikzpicture}[
    node distance=12.5 pt and 24pt,
    every node/.style={draw, circle, fill=black, inner sep=0pt},
                       minimum size=2.7ex, text=white]

\node (1)                       {1};
\node (2) [above right=of 1]    {2};
\node (3) [right=of 2]          {3};
\node (4) [below=of 1-| 2]      {4};
\node (5) [below=of 1-| 3]      {5};
\node (6) [right=of 3]          {6};
\node (7) [below=of 1-| 6]      {7};
\node (8) [right=of 6]          {8};
\node (9) [below=of 1-| 8]      {9};
\node (10)[below right=of 8]    {10};
\draw [line width=0.625pt]  (1) to  (2)
                            (1) to  (4)
                            (4) to  (5)
                            (2) to  (3)
                            (4) to  (2)
                            (5) to  (3)
                            (3) to  (6)
                            (5) to  (7)
                            (8) to  (6)
                            (7) to  (9)
                            (8) to  (10)
                            (9) to  (10)
                            (7) to  (6)
                            (9) to  (8);
\end{tikzpicture}

在序言中你需要添加\usetikzlibrary{positioning}。此代码生成以下图像：
