我已经定义了正 n 边形，逐个输出它们没有问题。但是，我想在一页上排列多个正 n 边形。运行我的代码时，有些图形超出了页边距。我该怎么做？

\documentclass[12pt,a4paper]{article}
\usepackage{tikz}
\begin{document}

% General function: Draw a regular n-sided polygon
\newcommand{\drawPolygon}[1]{%
    \begin{tikzpicture}
        \pgfmathsetmacro{\n}{#1} % Set the number of sides
        \pgfmathsetmacro{\angleStep}{360/\n} % Calculate the step angle for each side
        \pgfmathsetmacro{\startAngle}{-90 + \angleStep} % Calculate the starting angle
        % Draw vertices
        \foreach \i in {1,...,\n} {
            \node[draw, circle, fill=white, inner sep=2pt] (v\i) at ({\startAngle + (\i - 1) * \angleStep}:2) {};
        }
        % Connect adjacent vertices
        \foreach \i in {1,...,\n} {
            \pgfmathtruncatemacro{\next}{mod(\i, \n) + 1}
            \draw (v\i) -- (v\next);
        }
    \end{tikzpicture}
}


\begin{figure}
\centering
\begin{tikzpicture}
    \foreach [count=\i] \n in {3, 4, 5, 6, 7, 8, 9, 10} {
        \begin{scope}
            \drawPolygon{\n}
        \end{scope}
    }
\end{tikzpicture}
\caption{Regular 3- to 10-gons}
\end{figure}
\end{document}

我希望它以类似于网站（链接）的方式显示，每行 3 个项目，

另一个需要注意的问题是，当我使用图形标题时，标题和多边形中间之间的间隙似乎太大。

您不需要tikzpicture使用\foreach。我甚至会说您不应该嵌套tikzpictures。

\documentclass[12pt,a4paper]{article}
\usepackage{tikz}
\begin{document}

% General function: Draw a regular n-sided polygon
\newcommand{\drawPolygon}[2][1]{%
  \begin{tikzpicture}[scale=#1]
    \pgfmathsetmacro{\n}{#2} % Set the number of sides
    \pgfmathsetmacro{\angleStep}{360/\n} % Calculate the step angle for each side
    \pgfmathsetmacro{\startAngle}{-90 + \angleStep} % Calculate the starting angle
    % Draw vertices
    \foreach \i in {1,...,\n} {
      \node[draw, circle, fill=white, inner sep=2pt] (v\i) at
        ({\startAngle + (\i - 1) * \angleStep}:2) {};
    }
    % Connect adjacent vertices
    \foreach \i in {1,...,\n} {
      \pgfmathtruncatemacro{\next}{mod(\i, \n) + 1}
      \draw (v\i) -- (v\next);
    }
  \end{tikzpicture}
}


\begin{figure}
\centering

\foreach [count=\i] \n in {3, 4, ..., 10} {
  \makebox[0.2\textwidth]{%
    \begin{tabular}[t]{@{}c@{}}
      $n=\n$ \\[1ex]
      \drawPolygon[0.5]{\n}
    \end{tabular}%
  }\ifnum\i=4 \\[2ex]\fi
}

\caption{Regular 3- to 10-gons}

\end{figure}

\end{document}

我添加了一个可选参数来\drawPolygon设置比例。

每个多边形都排版在一个占文本宽度 20% 的框中；该框包含一个顶部对齐的框tabular，其中第一行是边数。在第四个多边形之后，插入一个换行符（具有垂直间距）。

像这样？

获取上图的一种方法是：

\documentclass[12pt,a4paper]{article}
\usepackage{tikz}
\usetikzlibrary{chains,
                positioning,
                shapes.geometric}

\begin{document}
    \begin{figure}[ht]
    \centering
\begin{tikzpicture}[
node distance = 23mm and 7mm,
  start chain = going right,
N/.style = {regular polygon, regular polygon sides=\i, minimum size=12mm, draw,
            node contents={}}
                    ]
\foreach \i in {3,...,5}%
{
    \node (n1\i)   [N, on chain];
\coordinate[above=3mm of n13] (y);
    \node at (y -| n1\i) {$n=\i$};
}
\foreach \i [count=\j from 3] in {6,...,8}%
{
    \node (n2\j)   [N, below=of y -| n1\j];
\coordinate[above=3mm of n23] (z);
    \node at (z -| n2\j) {$n=\i$};
}
\end{tikzpicture}
\caption{Regular 3- to 8-gons}
    \end{figure}
\end{document}

正如您所看到的，我使用Ti kregular polygon Z 库而不是您的宏。shapes.geometric

  • 還是很好的。
