产生相同错误的最小示例

以下代码块包含一个最小工作示例。它显示一组 2 行 3 列的圆圈，顶部有一个箭头（见下图中的结果）。

\documentclass{standalone}

\usepackage{tikz}

\usetikzlibrary{positioning}
\usetikzlibrary{decorations.markings}

\tikzset{
  clockwise/.style={
    decoration = {
      markings,
      mark = at position 0.25 with {\arrow{<}},
    },
    postaction = {decorate}
  }
}

\begin{document}
\begin{tikzpicture}
  % Row no. 1
  \coordinate(center11) at (0,0);
  \draw[clockwise, red] (center11) circle (0.1);

  \coordinate[right = 1 of center11] (center12);
  \draw[clockwise, red] (center12) circle (0.1);

  \coordinate[right = 1 of center12] (center13);
  \draw[clockwise, red] (center13) circle (0.1);

  % Row no. 2
  \coordinate[below = 1 of center11] (center21);
  \draw[clockwise, blue] (center21) circle (0.1);

  \coordinate[below = 1 of center12] (center22);
  \draw[clockwise, blue] (center22) circle (0.1);

  \coordinate[below = 1 of center13] (center23);
  \draw[clockwise, blue] (center23) circle (0.1);
\end{tikzpicture}
\end{document}

在此处输入图片描述

我现在尝试显示一组 3 行 3 列的相同圆圈，但Dimension too large.在尝试绘制第三行中的第一个节点时出现错误。下面的第一个代码块显示了我的尝试。下面的第二个代码块显示了错误的最后几行。

\documentclass{standalone}

\usepackage{tikz}

\usetikzlibrary{positioning}
\usetikzlibrary{decorations.markings}

\tikzset{
  clockwise/.style={
    decoration = {
      markings,
      mark = at position 0.25 with {\arrow{<}},
    },
    postaction = {decorate}
  }
}

\begin{document}
\begin{tikzpicture}
  % Row no. 1
  \coordinate(center11) at (0,0);
  \draw[clockwise, red] (center11) circle (0.1);

  \coordinate[right = 1 of center11] (center12);
  \draw[clockwise, red] (center12) circle (0.1);

  \coordinate[right = 1 of center12] (center13);
  \draw[clockwise, red] (center13) circle (0.1);

  % Row no. 2
  \coordinate[below = 1 of center11] (center21);
  \draw[clockwise, blue] (center21) circle (0.1);

  \coordinate[below = 1 of center12] (center22);
  \draw[clockwise, blue] (center22) circle (0.1);

  \coordinate[below = 1 of center13] (center23);
  \draw[clockwise, blue] (center23) circle (0.1);

  % Row no. 3
  \coordinate[below = 1 of center21] (center31);
  \draw[clockwise, red] (center31) circle (0.1);
\end{tikzpicture}

如何解决这个问题呢？

答案1

1mm您可以通过替换来避免错误0.1，它们是等效的。

请注意，您的代码相当于

\documentclass{standalone}

\usepackage{tikz}

\usetikzlibrary{positioning}
\usetikzlibrary{decorations.markings}

\tikzset{
  clockwise/.style={
    decoration = {
      markings,
      mark = at position 0.25 with {\arrow{<}},
    },
    postaction = {decorate}
  }
}

\begin{document}
\begin{tikzpicture}
  \foreach \i/\k [count=\n] in {0/red,1/blue,2/red}
    \foreach \j [count=\m] in {0,1,2}
      \draw [clockwise,\k] (\j cm,\i cm) coordinate (center\n\m) circle (1mm);
\end{tikzpicture}
\end{document}

3x3 顺时针卷发

您可能还会考虑pic为此使用，但除非您需要绘制很多，否则这可能会不必要地复杂。

答案2

加载fputikzlibrary 并使用如下所示的选项[/pgf/fpu/install only = {reciprocal}]。此解决方案在 PGF 手册的第 50.2 节“处理“尺寸过大”错误”中建议。

\documentclass{standalone}

\usepackage{tikz}

\usetikzlibrary{positioning}
\usetikzlibrary{decorations.markings}
\usetikzlibrary{fpu}

\tikzset{
  clockwise/.style={
    decoration = {
      markings,
      mark = at position 0.25 with {\arrow{<}},
    },
    postaction = {decorate}
  }
}

\begin{document}
\begin{tikzpicture}[/pgf/fpu/install only = {reciprocal}]
  % Row no. 1
  \coordinate(center11) at (0,0);
  \draw[clockwise, red] (center11) circle (0.1);

  \coordinate[right = 1 of center11] (center12);
  \draw[clockwise, red] (center12) circle (0.1);

  \coordinate[right = 1 of center12] (center13);
  \draw[clockwise, red] (center13) circle (0.1);

  % Row no. 2
  \coordinate[below = 1 of center11] (center21);
  \draw[clockwise, blue] (center21) circle (0.1);

  \coordinate[below = 1 of center12] (center22);
  \draw[clockwise, blue] (center22) circle (0.1);

  \coordinate[below = 1 of center13] (center23);
  \draw[clockwise, blue] (center23) circle (0.1);

  % Row no. 3
  \coordinate[below = 1 of center21] (center31);
  \draw[clockwise, red] (center31) circle (0.1);
\end{tikzpicture}
\end{document}

产生相同错误的最小示例

我找到了一个产生相同错误的更简单示例。以下代码块包含一个编译时没有错误的文档：

\documentclass{standalone}

\usepackage{tikz}

\usetikzlibrary{decorations.markings}

\tikzset{
  clockwise/.style={
    decoration = {
      markings,
      mark = at position 0.25 with {\arrow{<}},
    },
    postaction = {decorate}
  }
}

\begin{document}
\begin{tikzpicture}
  \coordinate(center1) at (0, 0);
  \draw[clockwise] (center1) circle (1mm);
  \coordinate(center2) at (0, 1);
  \draw[clockwise] (center2) circle (1mm);
\end{tikzpicture}
\end{document}

以下代码块向上面显示的示例添加了一个附加节点，并产生了相同的错误。

\documentclass{standalone}

\usepackage{tikz}

\usetikzlibrary{decorations.markings, fpu}

\tikzset{
  clockwise/.style={
    decoration = {
      markings,
      mark = at position 0.25 with {\arrow{<}},
    },
    postaction = {decorate}
  }
}

\begin{document}
\begin{tikzpicture}[/pgf/fpu/install only = {reciprocal}]
  \coordinate(center1) at (0, 0);
  \draw[clockwise] (center1) circle (1mm);
  \coordinate(center2) at (0, 1);
  \draw[clockwise] (center2) circle (1mm);
  \coordinate(center2) at (0, 2);
  \draw[clockwise] (center2) circle (1mm);
\end{tikzpicture}
\end{document}

这个问题可以用同样的方法解决：

\documentclass{standalone}

\usepackage{tikz}

\usetikzlibrary{decorations.markings, fpu}

\tikzset{
  clockwise/.style={
    decoration = {
      markings,
      mark = at position 0.25 with {\arrow{<}},
    },
    postaction = {decorate}
  }
}

\begin{document}
\begin{tikzpicture}[/pgf/fpu/install only = {reciprocal}]
  \coordinate(center1) at (0, 0);
  \draw[clockwise] (center1) circle (1mm);
  \coordinate(center2) at (0, 1);
  \draw[clockwise] (center2) circle (1mm);
  \coordinate(center2) at (0, 2);
  \draw[clockwise] (center2) circle (1mm);
\end{tikzpicture}
\end{document}
