如何在底部的每一列后添加描述？

Question

我想为第一列添加描述“column a”，为第二列添加描述“column b”，为第三列添加描述“column c”。该怎么做？

\documentclass{article}
\begin{document}
\begin{figure}[h!]
      \includegraphics[width=0.32\textwidth]{example-image-a}
      \includegraphics[width=0.32\textwidth]{example-image-b}
      \includegraphics[width=0.32\textwidth]{example-image-c}

      \includegraphics[width=0.32\textwidth]{example-image-a}
      \includegraphics[width=0.32\textwidth]{example-image-b}
      \includegraphics[width=0.32\textwidth]{example-image-c}

      \includegraphics[width=0.32\textwidth]{example-image-a}
      \includegraphics[width=0.32\textwidth]{example-image-b}
      \includegraphics[width=0.32\textwidth]{example-image-c}
      \caption{Column A $\rightarrow$ Column B $\rightarrow$ Column C. }
\end{figure}

\end{document}

Answer 1

通过表格实现更多控制的解决方案：

\documentclass{article}
\usepackage{graphicx}
\begin{document}
\begin{figure}[h!]
\begin{tabular}{c@{\hspace{1.5mm}}c@{\hspace{1.5mm}}c}
      \includegraphics[width=0.32\textwidth]{example-image-a}&
      \includegraphics[width=0.32\textwidth]{example-image-b}&
      \includegraphics[width=0.32\textwidth]{example-image-c}\\[0.1mm]
      \includegraphics[width=0.32\textwidth]{example-image-a}&
      \includegraphics[width=0.32\textwidth]{example-image-b}&
      \includegraphics[width=0.32\textwidth]{example-image-c}\\[0.1mm]
      \includegraphics[width=0.32\textwidth]{example-image-a}&
      \includegraphics[width=0.32\textwidth]{example-image-b}&
      \includegraphics[width=0.32\textwidth]{example-image-c}\\[0.1mm]
      (a) &
      (b) &
      (c)
      \end{tabular}
      \caption{Column A $\rightarrow$ Column B $\rightarrow$ Column C. }
\end{figure}

\end{document}

使用子图，参见相关问题。

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\usepackage{caption}
\usepackage{subcaption}



\begin{document}
\begin{figure}[t]
\centering
    \begin{subfigure}[t]{0.32\textwidth}
      \includegraphics{a}
      \includegraphics{a}
      \includegraphics{a}
      \subcaption{caption of Column A}
    \end{subfigure}
    \begin{subfigure}[t]{0.32\textwidth}
      \includegraphics{b}
      \includegraphics{b}
      \includegraphics{b}
      \subcaption{caption of Column B}
    \end{subfigure}
    \begin{subfigure}[t]{0.32\textwidth}
      \includegraphics{c}
      \includegraphics{c}
      \includegraphics{c}
      \subcaption{caption of Column C}
    \end{subfigure}
\caption{Caption of all the figures }
\end{figure}

\end{document}

您可以在图形环境中嵌套子图。

解决方案如下subfigure：

\documentclass{article}
\usepackage{graphicx}
\usepackage{subcaption}
\begin{document}
\begin{figure}[h!]
    \begin{subfigure}[t]{.32\linewidth}
      \includegraphics[width=\linewidth]{example-image-a}
      \includegraphics[width=\linewidth]{example-image-b}
      \includegraphics[width=\linewidth]{example-image-c}
      \caption{Column A $\rightarrow$}
\end{subfigure}
\begin{subfigure}[t]{.32\linewidth}
      \includegraphics[width=\linewidth]{example-image-a}
      \includegraphics[width=\linewidth]{example-image-b}
      \includegraphics[width=\linewidth]{example-image-c}
      \caption{Column B $\rightarrow$}
\end{subfigure}
\begin{subfigure}[t]{.32\linewidth}
      \includegraphics[width=\linewidth]{example-image-a}
      \includegraphics[width=\linewidth]{example-image-b}
      \includegraphics[width=\linewidth]{example-image-c}
      \caption{Column C. }
\end{subfigure}
\caption{Caption for all the three subfigures}
\end{figure}
\end{document}
