如何在插图下方添加单独的标题？

我如何为每幅插图添加单独的标题。左侧插图添加一个标题，右侧插图添加一个标题。两个标题都应位于插图下方。

我所指的插图在下面的代码中给出。

\begin{figure}[h]
    \centering
    \caption{Caption}
    \usetikzlibrary{arrows.meta,positioning}
\begin{center}
    \begin{tikzpicture}[
        node distance = 3mm and 20mm,
        arr/.style = {draw=blue!70!black, -{Straight Barb[scale=0.8]}, very thick},
          N/.style = {font=\small, text width=60mm, align=center, inner sep=2pt},
                                ]
        % left image
        \node (n1) [N]  {Set \mbox{$r_1=0$}\\
                         Anvend fast vindue $[0,r_2]$};
        \draw[thick]    (n1.west) -- ++ (0,-24mm)
                        (n1.east) -- ++ (0,-24mm);
                        %
        \coordinate[below=19mm of n1.west] (aux1);
        \path[arr]  (n1.east |- aux1) node[right] {$r_2$} --
                    (aux1) node[left] {$r_2$};
        % right image
        \node (n2) [N, right=of n1]  
                        {Set \mbox{$r\in[0,r_1-r_2]$}\\
                         Anvend fast termineringsvindue $[r_1,r_2]$};
        \draw[thick]    (n2.west) -- ++ (0,-24mm)
                        (n2.east) -- ++ (0,-24mm);
                        %
        \coordinate[below=19mm of n2.west] (aux2);
        \coordinate[above=of aux2] (aux3);
        \coordinate[above=of aux3] (aux4);
        \path[arr]  (n2.east |- aux2) --
                    (aux2) node[left] {$r_1$};
        \path[arr]  (n2.east |- aux3) node[right] {$r_2$} -- ++ 
                    (-36mm,0) node[left] {$r_1$};
        \path[arr]  (n2.east |- aux4) -- node[above] {$r_w=r_2-r_1$} ++
                    (-24mm,0) node[left] {$r_1$};
    \end{tikzpicture}
\end{center}
    \caption*{(a) ADF test (b) BSADF test}
    \label{fig:my_label}

在此处输入图片描述

一种方法是将图像拆分为两个图像并将每个图像插入到subfloat环境中：

\documentclass[border=3mm]{article}
\usepackage{geometry}
\usepackage{tikz}
\usetikzlibrary{arrows.meta,
                positioning}
\usepackage{subcaption}

\begin{document}
    \begin{figure}[ht]
\tikzset{
    node distance = 3mm,
    arr/.style = {draw=blue!70!black, -{Straight Barb[scale=0.8]}, very thick},
      N/.style = {font=\footnotesize, text width=54mm, align=center, inner sep=2pt},
        }
    \centering
\subfloat[ADF test]{%
% left image
    \begin{tikzpicture}
\node (n1) [N]  {Set \mbox{$r_1=0$}\\
                 Anvend fast vindue $[0,r_2]$};
\draw[thick]    (n1.west) -- ++ (0,-24mm)
                (n1.east) -- ++ (0,-24mm);
                %
\coordinate[below=19mm of n1.west] (aux1);
\path[arr]  (n1.east |- aux1) node[right] {$r_2$} --
            (aux1) node[left] {$r_2$};
    \end{tikzpicture}
                }%
\hfill%
\subfloat[BSADF test]{%
% right image
    \begin{tikzpicture}
\node (n2) [N]  {Set \mbox{$r\in[0,r_1-r_2]$}\\
                 Anvend fast termineringsvindue $[r_1,r_2]$};
\draw[thick]    (n2.west) -- ++ (0,-24mm)
                (n2.east) -- ++ (0,-24mm);
                %
\coordinate[below=19mm of n2.west] (aux2);
\coordinate[above=of aux2] (aux3);
\coordinate[above=of aux3] (aux4);
\path[arr]  (n2.east |- aux2) --
            (aux2) node[left] {$r_1$};
\path[arr]  (n2.east |- aux3) node[right] {$r_2$} -- ++
            (-36mm,0) node[left] {$r_1$};
\path[arr]  (n2.east |- aux4) -- node[above] {$r_w=r_2-r_1$} ++
            (-24mm,0) node[left] {$r_1$};
    \end{tikzpicture}
                }
\caption{Caption}
\label{fig:my_label}
    \end{figure}
\end{document}

使用包subfigure中定义的：subcaption

\documentclass[border=3mm]{article}
\usepackage{geometry}
\usepackage{tikz}
\usetikzlibrary{arrows.meta,
                positioning}
\usepackage{subcaption}

\begin{document}
    \begin{figure}[ht]
\tikzset{
    node distance = 3mm,
    arr/.style = {draw=blue!70!black, -{Straight Barb[scale=0.8]}, very thick},
      N/.style = {font=\footnotesize, text width=54mm, align=center, inner sep=2pt},
        }
    \centering
\caption{Caption}
\label{fig:my_label}
% left image
\begin{subfigure}{0.48\linewidth}
    \begin{tikzpicture}
\node (n1) [N]  {Set \mbox{$r_1=0$}\\
                 Anvend fast vindue $[0,r_2]$};
\draw[thick]    (n1.west) -- ++ (0,-24mm)
                (n1.east) -- ++ (0,-24mm);
                %
\coordinate[below=19mm of n1.west] (aux1);
\path[arr]  (n1.east |- aux1) node[right] {$r_2$} --
            (aux1) node[left] {$r_2$};
    \end{tikzpicture}
\caption{ADF test}
\end{subfigure}%
\hfill%
% right image
\begin{subfigure}{0.48\linewidth}
    \begin{tikzpicture}
\node (n2) [N]  {Set \mbox{$r\in[0,r_1-r_2]$}\\
                 Anvend fast termineringsvindue $[r_1,r_2]$};
\draw[thick]    (n2.west) -- ++ (0,-24mm)
                (n2.east) -- ++ (0,-24mm);
                %
\coordinate[below=19mm of n2.west] (aux2);
\coordinate[above=of aux2] (aux3);
\coordinate[above=of aux3] (aux4);
\path[arr]  (n2.east |- aux2) --
            (aux2) node[left] {$r_1$};
\path[arr]  (n2.east |- aux3) node[right] {$r_2$} -- ++
            (-36mm,0) node[left] {$r_1$};
\path[arr]  (n2.east |- aux4) -- node[above] {$r_w=r_2-r_1$} ++
            (-24mm,0) node[left] {$r_1$};
    \end{tikzpicture}
\caption{BSADF test}
\end{subfigure}
    \end{figure}
