Note below figure

Question

I have a figure and include it in LaTeX using \includegraphics in a \figure floating environment. The caption is at the top. Basically I would like to have a note below the figure too. I see some entries for tables but not for figures. Please suggest!

Answer 1

The floatrow package offers the \floatfoot macro for notes in addition to a float's \caption.

\documentclass{article}

\usepackage[capposition=top]{floatrow}

\begin{document}

\begin{figure}
% \centering% default with `floatrow`
\rule{1cm}{1cm}% placeholder for `\includegraphics`
\caption{A figure}
\floatfoot{A note}
\end{figure}

\end{document}

Answer 2

Another option is to use the \caption* command from the caption package:

\documentclass{article}
\usepackage{caption}

\begin{document}

\begin{figure}
\centering
\caption{A figure}
\rule{1cm}{1cm}% placeholder for `\includegraphics`
\caption*{A note}
\end{figure}

\end{document}

If the notes should use separate different formatting than the one used for the captions, a simple definition of a new command using \captionsetup will do the job:

\documentclass{article}
\usepackage{caption}

\newcommand\fnote[1]{\captionsetup{font=small}\caption*{#1}}

\begin{document}

\begin{figure}
\centering
\caption{A figure}
\rule{1cm}{1cm}% placeholder for `\includegraphics`
\fnote{A note}
\label{fig:test}
\end{figure}

\end{document}
