图形下方有一个标题，侧面有一个标题/图例

Question

我正在寻找一种方法来在图像的侧面添加图例，同时仍保留下面的标题。

我目前有以下代码：

\begin{figure}
\centering
\includegraphics[height=4cm]{example-image-a}
\caption{
    This is my caption
}
\label{fig:this-is-my-label}
\end{figure}

得到如下图像：

所以基本上我现在正在寻找一种方法来在图像的右侧或左侧添加图例。提前致谢！

Answer 1

借助环境minipage内部的两个 sidy by side figure，您可以实现以下目标：

\documentclass{article}

\usepackage{graphicx}
\usepackage[export]{adjustbox}

\begin{document}

\begin{figure}
\begin{minipage}{0.725\textwidth}
\hfill
\includegraphics[height=4cm]{example-image-a}
\end{minipage}
\hfill
\begin{minipage}{0.2\textwidth}
This is my legend. This is my legend.  This is my legend.  This is my legend.  This is my legend. 
\end{minipage}
\caption{This is my caption}
\label{fig:this-is-my-label}
\end{figure}

\begin{figure}
\begin{minipage}{0.2\textwidth}
This is my legend. This is my legend.  This is my legend.  This is my legend.  This is my legend. 
\end{minipage}
\hfill
\begin{minipage}{0.725\textwidth}
\includegraphics[height=4cm]{example-image-a}
\end{minipage}
\caption{This is my caption}
\label{fig:this-is-my-label}
\end{figure}

\begin{figure}
\begin{minipage}[t]{0.725\textwidth}
\hfill
\includegraphics[height=4cm,valign=t]{example-image-a}
\end{minipage}
\hfill
\begin{minipage}[t]{0.2\textwidth}
This is my legend. This is my legend.  This is my legend.  This is my legend.  This is my legend. 
\end{minipage}
\caption{This is my caption}
\label{fig:this-is-my-label}
\end{figure}

\end{document}

\documentclass{article}
\usepackage[export]{adjustbox}
\usepackage{tabularx}

\begin{document}
    \begin{figure}[ht]
\centering
\begin{tabularx}{0.8\linewidth}{XX}
\includegraphics[height=4cm, width=\linewidth, keepaspectratio,
                 valign=c]{example-image-duck} 
    &   Legend: some long explanation of image  \\
\caption{This is my caption in two lines}
\label{fig:this-is-my-label}
    &
    \end{tabularx}
    \end{figure}
or
    \begin{figure}[ht]
\centering
\begin{tabularx}{0.8\linewidth}{XX}
\includegraphics[height=4cm, width=\linewidth, keepaspectratio,
                 valign=c]{example-image-duck}
    &   Legend: some long explanation of image  \\
    \end{tabularx}
\caption{This is my caption in one line}
\label{fig:this-is-my-label}
    \end{figure}
\end{document}
