减少图中禁忌和子浮点之间的差距

Question

我在图形功能块中有一个禁忌和一个子浮点数。如何减少禁忌和子浮点数之间的间距？下面是我的代码和图形。我想要一个简单的解决方案，不需要我重组我的代码。我想减少 x1 x2 x3 等与其下方的子浮点数之间的间隙

\begin{figure}
\captionsetup[subfigure]{labelformat=empty}
    \centering
    {\scriptsize
    \begin{tabu} to \textwidth { XXXXXXXXXXXXXXXXXXXX }

Answer 1

编辑：表格似乎在表格和子标题之间引入了额外的垂直空间。可以通过在表格结束前添加负垂直空间来减少这种情况：

...
\vspace*{-3pt}%
\end{tabu}}

修改的我的答案 使用tabu代替tabularx表：

 \documentclass{article}
\usepackage[margin=20mm]{geometry}
\usepackage[demo]{graphicx}
\usepackage{tabu}
\usepackage{subfig}

\begin{document}
    \begin{figure}
    \centering
\captionsetup[subfigure]{labelformat=empty}
\subfloat[ sub caption text]{% <--- had to be here
    \setlength\tabcolsep{0pt}% <--- had to be here
\begin{tabu} to \textwidth {*{11}{X[c,$]}}
\alpha=0 & \alpha=1 & \alpha=2 & \alpha=3 & \alpha=4 & \alpha=5 
         & \alpha=6 & \alpha=7 & \alpha=8 & \alpha=9 & \alpha=10    \\
\multicolumn{11}{c}{\includegraphics[width=\textwidth]{latent/latent-interpolation.png} }
\vspace*{-3pt}%
\end{tabu}}

\subfloat[ sub caption text]%
{\includegraphics[width=\textwidth]{latent/latent-interpolation.png}}
\caption{Interpolating between random pairs of latent vectors according to $v = v_1 + (v_2 - v_1) \times \alpha$.}
\label{fig:interpolate-latent}
    \end{figure}
\end{document}

我认为subfloats 之间的间距适当大一些。
