带有三个标题的图形，我只希望其中一个出现在图形列表中

Question

我有一张占三页的图。它由子图组成。这三个图的标题必须相同。这是一个例子：

请注意，每个图出现在不同的页面中。

正如预期，图表列表将显示以下内容：

1 这是标题.......................................................................................................................................................................................................1

1 这是标题。......................................................................................................................................................................................2

1 这是标题.......................................................................................................................................................................................................3

这就是问题出现的地方：如何防止同一个图形在图形列表中出现三次？在第一页上对图表进行索引就足够了。

这是一个完整的例子：

\documentclass{article}
    \usepackage[utf8]{inputenc}
    \usepackage[labelformat=simple]{subcaption}
    \renewcommand\thesubfigure{(\alph{subfigure})}
    \usepackage{graphicx}
    \title{Example}

\newcommand\metric[1]{\ensuremath{\text{metric}\paren{#1}}}

\begin{document}

\maketitle

\listoffigures

\section{Introduction}


 \begin{figure}[htb]
    \centering
    \begin{subfigure}[b]{\textwidth}
        \centering
        \includegraphics[width=\textwidth]{example-image-a}
        \caption*{\hfil \textit{continued on the next page}}
     \end{subfigure}
          \caption{This is a caption.}
\end{figure}
    %
\begin{figure}[htb]\ContinuedFloat
    \centering
    \begin{subfigure}[b]{\textwidth}
         \centering
         \includegraphics[width=\textwidth]{example-image-b}
                 \caption*{\hfil \textit{continued on the next page}}
     \end{subfigure}
          \caption{This is a caption.}
          \end{figure}
    %
    \begin{figure}[htb]\ContinuedFloat
        \centering
     \begin{subfigure}[tb]{\textwidth}
         \centering
         \includegraphics[width=\textwidth]{example-image-c}
     \end{subfigure}
          \caption{This is a caption.}
    \label{fig:label}
\end{figure}

Answer 1

您可以添加一个空的可选参数到\caption，例如\caption[]{This is a caption.}。而没有必要使用subfigure。

\documentclass{article}
\usepackage{caption}
\usepackage{graphicx}
\title{Example}
\begin{document}
\maketitle
\listoffigures
\section{Introduction}
\begin{figure}[htb]
\centering
\includegraphics[width=\textwidth]{example-image-a}
{\mbox{}\hfill\textit{continued on the next page}\hskip1cm}
\caption{This is a caption.}
\end{figure}
\begin{figure}[htb]\ContinuedFloat
\centering
\includegraphics[width=\textwidth]{example-image-b}
{\mbox{}\hfill\textit{continued on the next page}\hskip1cm}
\caption[]{This is a caption.}
\end{figure}
\begin{figure}[htb]\ContinuedFloat
\centering
\includegraphics[width=\textwidth]{example-image-c}
\caption[]{This is a caption.}
\label{fig:label}
\end{figure}
\end{document}
