子图标题

Question

我正在使用以下脚本显示一个图形。问题是我不知道如何为每个子图添加子标题。我不想使用任何其他包。有什么建议吗？

\begin{figure}
\includegraphics[width=0.32\linewidth]{fig1.png}
\includegraphics[width=0.32\linewidth]{fig2.png}
\includegraphics[width=0.32\linewidth]{fig3.png}\\
\includegraphics[width=0.32\linewidth]{fig4.png}
\includegraphics[width=0.32\linewidth]{fig5.png}
\includegraphics[width=0.32\linewidth]{fig6.png}

\caption{big_caption.}
\label{label1}
\end{figure}

Answer 1

如果您不想让子图标题出现在\listoffigures并且您可以记住字母表，您可以使用：

\documentclass{article}
\usepackage{mwe}% for images only
\begin{document}
\begin{figure}
\centering
\includegraphics[width=0.32\linewidth]{example-image}
\includegraphics[width=0.32\linewidth]{example-image}
\includegraphics[width=0.32\linewidth]{example-image}
\par
\makebox[0.32\linewidth]{(a)}
\makebox[0.32\linewidth]{(b)}
\makebox[0.32\linewidth]{(c)}
\vspace{\baselineskip}\par
\includegraphics[width=0.32\linewidth]{example-image}
\includegraphics[width=0.32\linewidth]{example-image}
\includegraphics[width=0.32\linewidth]{example-image}
\par
\makebox[0.32\linewidth]{(d)}
\makebox[0.32\linewidth]{(e)}
\makebox[0.32\linewidth]{(f)}
\vspace{\baselineskip}\par
\caption{big caption.}
\label{label1}
\end{figure}
\end{document}
