两张不同的 tikzpictures 的同一行有两个标题

Question 1

更新： 参考您的评论。这是一个解决方案，用图 1 代替 AAAA，用图 2 代替 BBBB。因此，两个图都会列出。该解决方案类似于/相当于两个并排的身影。

错误/旧版本：

像这样？

类似于我的回答这里您可以像下面这样操作。标签 Q、VQ、Q 和 VQ 都用简单的来添加\nodes。而不是subfigurei usd subfloat。我还稍微缩放了您的省略号，希望没问题。

\usepackage{hyperref}
\usepackage{tikz}
\usepackage{subfig}

\def\drawORnot{2}% 1-> bounding box on; else -> bounding box off
\usepackage{ifthen}

\newcommand{\drawboundingbox}[2][red]{
  \ifthenelse{\equal{#2}{1}}
    {
    \draw [#1] (current bounding box.south west) rectangle (current bounding box.north east);
    }
    {
    %FALSE
    }%
