如何在图表下添加标题

如何在两个图表下添加标题（每个图表一个）？以下是代码

\begin{center}
\tikzset{ellipsenode/.style={draw, ellipse, thick, text width=5ex, align=center, inner sep=2pt}}
\begin{tikzpicture}[node distance={1mm}, thick]
\node (center) [circle] {};
\node (1) at ($(center)+(240:25mm)$)[ellipsenode] {$y_{1}$};
\node (2) at ($(center)+(300:25mm)$)[ellipsenode] {$y_{2}$};
\node (3) at ($(center)$)[ellipsenode] {$y_{3}$}; 
\node (4) at ($(center)+(60:25mm)$)[ellipsenode] {$y_{4}$};
\node (5) at ($(center)+(120:25mm)$)[ellipsenode] {$y_{5}$}; 
\draw[-] (1) -- (3);
\draw[-] (1) -- (2);
\draw[-] (2) -- (3);
\draw[-] (4) -- (3);
\draw[-] (5) -- (3);
\draw[-] (5) -- (4);
\end{tikzpicture} 

\hspace{30mm}
\tikzset{ellipsenode/.style={draw, ellipse, thick, text width=5ex, align=center, inner sep=2pt}}
\begin{tikzpicture}[node distance={1mm}, thick]
\node (center) [circle] {};
\node (1) at ($(center)+(240:25mm)$)[ellipsenode] {$y_{1}$};
\node (2) at ($(center)+(300:25mm)$)[ellipsenode] {$y_{2}$};
\node (3) at ($(center)$)[ellipsenode] {$y_{3}$}; 
\node (4) at ($(center)+(60:25mm)$)[ellipsenode] {$y_{4}$};
\node (5) at ($(center)+(120:25mm)$)[ellipsenode] {$y_{5}$}; 
\draw[-] (1) -- (3);
\draw[-] (1) -- (2);
\draw[-] (2) -- (3);
\draw[-] (5) -- (3);
\end{tikzpicture} 
\end{center}

答案1

我假设您希望有两张带有自己标题的平行图片。您可以通过将图片放入tabularx表格中轻松实现这一点：

在此处输入图片描述

在下面的 MWE（最小工作示例）中，使用环境保留它们在文档中的插入center，并使用包\captionof {figure}{<caption text>}中定义的标题caption，或者您可以使用小包capt-of ：

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{positioning,
                shapes.geometric}
\usepackage{caption}
\usepackage{tabularx}
\newcolumntype{C}{>{\centering\arraybackslash}X}

\begin{document}
    \begin{center}
\tikzset{ellipsenode/.style = {% common style for nodes
    ellipse, draw, thick, text width=2em, align=center, inner sep=2pt},
         node distance = 21mm and 7mm
}
    \begin{tabularx}{\linewidth}{@{} C @{\hspace{30mm}} C @{}}
    \begin{tikzpicture}
    \begin{scope}[nodes=ellipsenode]
\node (1) {$y_{1}$};
\node (2) [above right=of 1] {$y_{3}$};
\node (3) [below right=of 2] {$y_{2}$};
\node (4) [above  left=of 2] {$y_{5}$};
\node (5) [above right=of 2] {$y_{4}$};
    \end{scope}
%
\draw   (1) -- (3) -- (2) -- (1)
        (2) -- (4) -- (5) -- (2);
    \end{tikzpicture}
\captionof{figure}{Caption of left diagram}
\label{fig:diagram-left}
    &
    \begin{tikzpicture}
    \begin{scope}[nodes=ellipsenode]
\node (1) {$y_{1}$};
\node (2) [above right=of 1] {$y_{3}$};
\node (3) [below right=of 2] {$y_{2}$};
\node (4) [above  left=of 2] {$y_{5}$};
\node (5) [above right=of 2] {$y_{4}$};
    \end{scope}
%
\draw   (1) -- (3) -- (2) -- (1)
        (2) -- (4);
    \end{tikzpicture}
\captionof{figure}{Caption of right diagram}
\label{fig:diagram-right}
\end{tabularx}
    \end{center}
\end{document}

但是，如果您希望将图形浮动到文档中的最佳位置，您只需替换center并figure使用标准标题命令：

% preamble
    \begin{figure}[ht]
\tikzset{ellipsenode/.style = {% common style for nodes
    ellipse, draw, thick, text width=2em, align=center, inner sep=2pt},
         node distance = 21mm and 7mm
}
    \begin{tabularx}{\linewidth}{@{} C @{\hspace{30mm}} C @{}}
    \begin{tikzpicture}
    \begin{scope}[nodes=ellipsenode]
\node (1) {$y_{1}$};
\node (2) [above right=of 1] {$y_{3}$};
\node (3) [below right=of 2] {$y_{2}$};
\node (4) [above  left=of 2] {$y_{5}$};
\node (5) [above right=of 2] {$y_{4}$};
    \end{scope}
%
\draw   (1) -- (3) -- (2) -- (1)
        (2) -- (4) -- (5) -- (2);
    \end{tikzpicture}
\caption{Caption of left diagram}
\label{fig:diagram-left}
    &
    \begin{tikzpicture}
    \begin{scope}[nodes=ellipsenode]
\node (1) {$y_{1}$};
\node (2) [above right=of 1] {$y_{3}$};
\node (3) [below right=of 2] {$y_{2}$};
\node (4) [above  left=of 2] {$y_{5}$};
\node (5) [above right=of 2] {$y_{4}$};
    \end{scope}
%
\draw   (1) -- (3) -- (2) -- (1)
        (2) -- (4);
    \end{tikzpicture}
\caption{Caption of right diagram}
\label{fig:diagram-right}
\end{tabularx}
    \end{figure}

我擅自更改了您的图表代码：

  • 定义了两张图片的共同节点样式，
  • 通过使用positioningTi钾Z 库节点彼此相对定位。
  • 节点按以下方式分组scope
  • 节点之间的连接以两个循环的形式绘制

现在代码稍微短一点。

最好的方法是在 -environment\caption中使用figure。使用方式如下：

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{calc}
\usetikzlibrary{shapes.geometric}

\begin{document}
    \begin{figure}[ht!]
        \centering
        \tikzset{ellipsenode/.style={draw, ellipse, thick, text width=5ex, align=center, inner sep=2pt}}
        \begin{tikzpicture}[node distance={1mm}, thick]
            \node (center) [circle] {};
            \node (1) at ($(center)+(240:25mm)$)[ellipsenode] {$y_{1}$};
            \node (2) at ($(center)+(300:25mm)$)[ellipsenode] {$y_{2}$};
            \node (3) at ($(center)$)[ellipsenode] {$y_{3}$}; 
            \node (4) at ($(center)+(60:25mm)$)[ellipsenode] {$y_{4}$};
            \node (5) at ($(center)+(120:25mm)$)[ellipsenode] {$y_{5}$}; 
            \draw[-] (1) -- (3);
            \draw[-] (1) -- (2);
            \draw[-] (2) -- (3);
            \draw[-] (4) -- (3);
            \draw[-] (5) -- (3);
            \draw[-] (5) -- (4);
        \end{tikzpicture}
        \caption{Some cool figure}
    \end{figure}

    \begin{figure}[ht!]
        \centering
        \tikzset{ellipsenode/.style={draw, ellipse, thick, text width=5ex, align=center, inner sep=2pt}}
        \begin{tikzpicture}[node distance={1mm}, thick]
            \node (center) [circle] {};
            \node (1) at ($(center)+(240:25mm)$)[ellipsenode] {$y_{1}$};
            \node (2) at ($(center)+(300:25mm)$)[ellipsenode] {$y_{2}$};
            \node (3) at ($(center)$)[ellipsenode] {$y_{3}$}; 
            \node (4) at ($(center)+(60:25mm)$)[ellipsenode] {$y_{4}$};
            \node (5) at ($(center)+(120:25mm)$)[ellipsenode] {$y_{5}$}; 
            \draw[-] (1) -- (3);
            \draw[-] (1) -- (2);
            \draw[-] (2) -- (3);
            \draw[-] (5) -- (3);
        \end{tikzpicture}
        \caption{Another cool figure}  
    \end{figure}
\end{document}

Tikz 带标题

您还可以将数字放在每个数字旁边：将两幅图像放在一起

这回答了你的问题吗？
