设置标题的行长度

Question

我尝试使用 subfigure 将两个图形放在一起，但不幸的是 LaTeX 将它们放在了右边。我过去常常hspace缩小它们之间的间距，结果导致标题混乱。所以我认为解决方案可能是更改行的长度，使标题行自动换行。

\begin{figure}[~hbt]
\subfigure[Nonuniform distribution of points on sphere when the $n$-spherical coordinates are uniformly chosen from related intervals]
{
\includegraphics[scale=0.4]{sphere}
}
\hspace{-3em}
\subfigure[Nonuniform distribution of points on cube when the points on left figure has been transformed using the mentioned diffeomorphism]
{
\includegraphics[scale=0.4]{cube}
}

\end{figure}

任何其他解决方案也受到欢迎。

Answer 1

这是一个使用该subcaption包的解决方案（该subfigure包已被弃用）。

\documentclass{article}
\pagestyle{empty}% for cropping
\usepackage{subcaption}
\usepackage[demo]{graphicx}
\begin{document}
\begin{figure}[hbt]
    \begin{subfigure}[t]{.45\linewidth}
        \centering
        \includegraphics[scale=0.4]{sphere}
        \caption{Nonuniform distribution of points on sphere when the $n$-spherical coordinates are uniformly chosen from related intervals}
    \end{subfigure}
    \hspace{.06\linewidth}
    \begin{subfigure}[t]{.45\linewidth}
        \centering
        \includegraphics[scale=0.4]{cube}
        \caption{Nonuniform distribution of points on cube when the points on left figure has been transformed using the mentioned diffeomorphism}
    \end{subfigure}
    \caption{Caption for the overall figure}
\end{figure}
\end{document}
