如何从乳胶中的子图标题中消除括号？

Question

我遇到的问题是，当我编译时，图像标题显示带有括号“[图标题]”......................................................................................................................................

 \documentclass{elsarticle}
    \usepackage{verbatim}

\usepackage{amsthm}
\begin{figure}
         \subfigure[]{ \includegraphics[width=0.24\textwidth]{graph1}
            } 
             \subfigure[]{\includegraphics[width=0.24\textwidth]{graph2}%
             }
              \subfigure[]{\includegraphics[width=0.24\textwidth]{graph3}}%
\caption{Three simple graphs}
        \label{fig:three graphs}
\end{figure}

Answer 1

由于您正在加载caption包，因此我会使用高度兼容的subcaption包的机制，而不是仅仅有点兼容的subfig包的机制。

（下图中的框线表示文本块的边缘。）

\documentclass[demo]{elsarticle} % remove 'demo' option in real doc
    %% preamble reduced the bare minimum
    \usepackage{graphicx,caption,subcaption}
    \captionsetup[subfigure]{labelformat=simple}

\begin{document}
\begin{figure}[ht!]
\centering
\begin{subfigure}{0.24\linewidth}
  \includegraphics[width=\textwidth]{graph1}
  \caption{}
\end{subfigure}\qquad
\begin{subfigure}{0.24\linewidth}
  \includegraphics[width=\textwidth]{graph2}
  \caption{}
\end{subfigure}\qquad
\begin{subfigure}{0.24\linewidth}
  \includegraphics[width=\textwidth]{graph3}
  \caption{}
\end{subfigure}
\caption{Three simple graphs}\label{fig:three graphs}
\end{figure}
\end{document}

Answer 2

在删除所有不相关的包并使用正确的子图语法（参见@leandriis 评论）后，MWE 是

\documentclass{elsarticle}
\usepackage{graphicx}
\usepackage{caption}
\usepackage[labelformat=simple]{subfig} % <----

\begin{document}
\begin{figure}
\centering
         \subfloat[]{\includegraphics[width=0.24\textwidth]{example-image-a}
            }\hfil
         \subfloat[]{\includegraphics[width=0.24\textwidth]{example-image-b}%
             }\hfil
         \subfloat[]{\includegraphics[width=0.24\textwidth]{example-image-c}}%
\caption{Three simple graphs}
        \label{fig:three graphs}
\end{figure}
\end{document}
