我试过:
\begin{figure*}
\centering
\begin{subfigure}[b]{0.25\textwidth}
\includegraphics[width=\textwidth]{figures/a}
\caption{a}
\label{fig:a}
\end{subfigure}%
\begin{subfigure}[b]{0.25\textwidth}
\includegraphics[width=\textwidth]{figures/b}
\caption{b}
\label{fig:b}
\end{subfigure}
\begin{subfigure}[b]{0.25\textwidth}
\includegraphics[width=\textwidth]{figures/c}
\caption{c}
\label{fig:c}
\end{subfigure}
\begin{subfigure}[b]{0.25\textwidth}
\includegraphics[width=\textwidth]{figures/d}
\caption{d}
\label{fig:d}
\end{subfigure}
\caption{Pictures of ABCD}\label{fig:ABCD}
\end{figure*}
但这些数字垂直显示在一列上!我怎样才能让这 4 个数字水平显示在两列上
答案1
子图环境之间的空行会导致图形环境内的换行,因此删除您想要在生成的文档中保留在同一行的那些空行会得到所需的结果:
\begin{figure*}
\centering
\begin{subfigure}[b]{0.25\textwidth}
\includegraphics[width=\textwidth]{figures/a}
\caption{a}
\label{fig:a}
\end{subfigure}
\begin{subfigure}[b]{0.25\textwidth}
\includegraphics[width=\textwidth]{figures/b}
\caption{b}
\label{fig:b}
\end{subfigure}
\begin{subfigure}[b]{0.25\textwidth}
\includegraphics[width=\textwidth]{figures/c}
\caption{c}
\label{fig:c}
\end{subfigure}
\begin{subfigure}[b]{0.25\textwidth}
\includegraphics[width=\textwidth]{figures/d}
\caption{d}
\label{fig:d}
\end{subfigure}
\caption{Pictures of ABCD}\label{fig:ABCD}
\end{figure*}
附录:
如果您想保持源代码的可读性,您也可以“注释掉空白行”——可以这么说:
\begin{figure*}
\centering
\begin{subfigure}[b]{0.25\textwidth}
\includegraphics[width=\textwidth]{figures/a}
\caption{a}
\label{fig:a}
\end{subfigure}
% this comment avoids break-line...
\begin{subfigure}[b]{0.25\textwidth}
\includegraphics[width=\textwidth]{figures/b}
\caption{b}
\label{fig:b}
\end{subfigure}
\begin{subfigure}[b]{0.25\textwidth}
\includegraphics[width=\textwidth]{figures/c}
\caption{c}
\label{fig:c}
\end{subfigure}
% ... this comment too
\begin{subfigure}[b]{0.25\textwidth}
\includegraphics[width=\textwidth]{figures/d}
\caption{d}
\label{fig:d}
\end{subfigure}
\caption{Pictures of ABCD}\label{fig:ABCD}
\end{figure*}
