我想在 LaTeX 中实现这张图片以显示偶极子的辐射。我已经问过这个问题了辐射图。但是，我需要为每个图表添加标题而不使用\subcaption！（因为在我的代码中我需要用于\subfigure其他东西，而我们不能同时使用\subcaption，\subfigure......）
我的代码如下（取自marmot 的回答）到链接的问题：
\documentclass[11pt,a4paper]{article}
\usepackage{subcaption}
\usepackage{floatrow}
\usepackage{pgfplots}
\pgfplotsset{width=8cm,compat=1.16}
\usepgfplotslibrary{polar}
\begin{document}
\begin{figure}[htb]
\floatsetup{valign=c, heightadjust=all}
\ffigbox{%
\begin{subfloatrow}
\ffigbox{\begin{tikzpicture}
\begin{axis}[view/h=45,axis lines = none,unit vector ratio=1 1 1]
\addplot3[domain=0:360,domain y=0:360,samples=31,
point meta=sqrt(x^2+y^2),
colormap/blackwhite,surf,%mesh,point meta=1, %<-if you want a mesh
z buffer=sort]
({(sin(x+90)*sin(x+90))*cos(y)},
{(sin(x+90)*sin(x+90))*sin(y)},
{(sin(x+90)*sin(x+90))*sin(x)});
\end{axis}
\path(current bounding box.south west) rectangle (current bounding box.north
east);
\end{tikzpicture}}{\caption{Diagramme de rayonnement du dipôle.\label{fig:Diagramme de rayonnement du dipôle}}}
\ffigbox{\begin{tikzpicture}
\begin{polaraxis}[axis lines = none]
\addplot[domain=0:360,samples=73,smooth] (x+90,{sin(x)*sin(x)});
\end{polaraxis}
\draw[-stealth] ([yshift=2cm]current axis.south) -- ([yshift=-2cm]current axis.north);
\end{tikzpicture}}{\caption{Coupe verticale du diagramme de rayonnement.\label{fig:Coupe verticale du diagramme de rayonnement}}}
\end{subfloatrow}}
{\caption{Rayonnement du dipôle demi-onde.}\label{fig:Rayonnement du dipôle demi-onde}}
\end{figure}
\end{document}

上图的 mwe 为：
\documentclass{article}
\usepackage[export]{adjustbox}
\usepackage{tabularx}
\begin{document}
\begin{figure}[htb]
\begin{tabularx}{\linewidth}{*{2}{>{\centering\arraybackslash}X}}
\includegraphics[width=\linewidth]{example-image-duck}
\caption{3D presentation of dipole radiation}
\label{fig:dipol-1}
&
\includegraphics[width=\linewidth, height=3cm]{example-image-duck}
\caption{3D presentation of dipole radiation}
\label{fig:dipol-2}
\end{tabularx}
\end{figure}
or
\begin{figure}[htb]
\begin{tabularx}{\linewidth}{*{2}{>{\centering\arraybackslash}X}}
\includegraphics[width=\linewidth,valign=c]{example-image-duck}
&
\includegraphics[width=\linewidth, height=3cm,valign=c]{example-image-duck}\\
%
\caption{3D presentation of dipole radiation}
\label{fig:dipol-1}
&
\caption{3D presentation of dipole radiation}
\label{fig:dipol-2}
\end{tabularx}
\end{figure}
\end{document}
如果您喜欢包含图像代码，则用它们替换它们\includegraphics ...，并使用 选项进行垂直对齐baseline ...。tikzpicture由于您不提供 mwe，我无法显示更多内容。

按照对问题的编辑（使用来自的代码https://tex.stackexchange.com/a/467985），如果我理解正确的话，您正在寻找以下内容：
它是用以下内容生成的姆韦：

为了获得上面的图像，我评论（已删除）包floatrow。你真的需要它吗？显然，它以某种方式重新定义了figure环境中字幕的外观（只允许一个字幕），因此在上面姆韦导致错误。
就我所见，您的文档中使用的几乎所有内容都可以通过subcaption包实现：

% however it is troublemaker. do you really need it?

在这两种情况下，我都稍微修正了第二幅图（参见 mwe）
