tikz 图片中的顶点标签

我已经使用 tikz 绘制了几个图形。现在我得到的是顶点内部的顶点标签。但我想要的是顶点外部的顶点标签。

另外，我想在一行中绘制两个 tickz 图片。请帮忙。我正在使用以下代码。

\documentclass[11pt]{article}
\usepackage{graphicx}
\usepackage{tikz}
\usepackage{caption}

\begin{document}

\begin{figure}[h]
\centering
\begin{tikzpicture}
\begin{scope}[every node/.style={fill=white,circle,thick,draw}]
    \node(A) at (1,1) {1};
    \node(B) at (0,0) {2};
    \node(C) at (1,-1) {3};
\end{scope}
\begin{scope}
            [every edge/.style={draw=black,very thick}]
    \path[-](A)edge node {} (B);
    \path[-](B) edge node {} (C);
\end{scope}
\end{tikzpicture}
\caption*{Figure 1}
\end{figure}

\medskip

\begin{figure}[h]
\centering
\begin{tikzpicture}
\begin{scope}[every node/.style={fill=white,circle,thick,draw}]
    \node(A) at (0,0) {2};
    \node(B) at (-1,1) {4};
    \node(C) at (1,1) {6};
    \node(D) at (1,-1) {8};
    \node(E) at (-1,-1) {10};
\end{scope}
\begin{scope}
            [every edge/.style={draw=black,very thick}]
    \path[-](A)edge node {} (B);
    \path[-](A) edge node {} (C);
    \path[-](A) edge node {} (D);
    \path[-](A) edge node {} (E);
\end{scope}
\end{tikzpicture}
\caption*{Figure 2}
\end{figure}
\end{document}

另一种选择是基于假设，您希望两个图形并排而不是子图形：

在此处输入图片描述

\documentclass[11pt]{article}
\usepackage{graphicx}
\usepackage{tikz}
\usepackage{caption}
\usepackage{tabularx}

    \begin{document}  
\begin{figure}[h]
\centering
    \begin{tabularx}{0.8\textwidth}{*{2}{>{\centering\arraybackslash}X}}
\begin{tikzpicture}[
every edge/.style = {draw=black,very thick},
 vrtx/.style args = {#1/#2}{% 
      circle, draw, thick, fill=white,
      minimum size=5mm, label=#1:#2}
                    ]
\node(A) [vrtx=left/1] at (1, 1) {};
\node(B) [vrtx=left/2] at (0, 0) {};
\node(C) [vrtx=left/3] at (1,-1) {};
%
\path   (A) edge (B)
        (B) edge (C);
\end{tikzpicture}
    \caption*{Figure 1}  
    &   
\begin{tikzpicture}[
every edge/.style = {draw=black,very thick},
 vrtx/.style args = {#1/#2}{%
      circle, draw, thick, fill=white,
      minimum size=5mm, label=#1:#2}
                    ]
\node (A) [vrtx=left/2]     at ( 0, 0) {};
\node (B) [vrtx=left/4]     at (-1, 1) {};
\node (C) [vrtx=right/6]    at ( 1, 1) {};
\node (D) [vrtx=right/8]    at ( 1,-1) {};
\node (E) [vrtx=left/10]    at (-1,-1) {};
 %
\path   (A) edge (B)
        (A) edge (C)
        (A) edge (D)
        (A) edge (E);
\end{tikzpicture}
\caption*{Figure 2}  
    \end{tabularx}
\end{figure} 
\end{document}

我还稍微修改了代码，使其更简洁易用（省略了scope定义的节点，以便简单设置它们的标签，省略了未使用的节点和边。数字放在tabularx表格中。

附录： 如果你想将一行中的图形组织为子图形：

\documentclass[11pt]{article}
\usepackage{graphicx}
\usepackage{tikz}
\usepackage{caption}
\usepackage{subcaption}

\begin{document}

\begin{figure}[h]
\centering
    \begin{subfigure}[b]{0.4\textwidth}\centering
\begin{tikzpicture}[
every edge/.style = {draw=black,very thick},
 vrtx/.style args = {#1/#2}{%
      circle, draw, thick, fill=white,
      minimum size=5mm, label=#1:#2}
                    ]
\node(A) [vrtx=left/1] at (1, 1) {};
\node(B) [vrtx=left/2] at (0, 0) {};
\node(C) [vrtx=left/3] at (1,-1) {};
%
\path   (A) edge (B)
        (B) edge (C);
\end{tikzpicture}
    \caption{}
    \end{subfigure}
\hfil    
    \begin{subfigure}[b]{0.4\textwidth}\centering
\begin{tikzpicture}[
every edge/.style = {draw=black,very thick},
 vrtx/.style args = {#1/#2}{%
      circle, draw, thick, fill=white,
      minimum size=5mm, label=#1:#2}
                    ]
\node (A) [vrtx=left/2]     at ( 0, 0) {};
\node (B) [vrtx=left/4]     at (-1, 1) {};
\node (C) [vrtx=right/6]    at ( 1, 1) {};
\node (D) [vrtx=right/8]    at ( 1,-1) {};
\node (E) [vrtx=left/10]    at (-1,-1) {};
 %
\path   (A) edge (B)
        (A) edge (C)
        (A) edge (D)
        (A) edge (E);
\end{tikzpicture}
\caption{}
    \end{subfigure}
\caption{Common caption}
    \label{fig:figure-3}
\end{figure}
    \end{document}

在上面 MWE 中使用了subfigure来自包的环境subcaption。
