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}

Answer 3

Another option:

\begin{figure}
    \centering
    \includegraphics[scale=YOUR_FIGURE_SCALE]{YOUR_FIGURE.pdf}
    \begin{minipage}{YOUR_SPECIFIED_WIDTH}
    \footnotesize
    \emph{YOUR NOTES}
    \end{minipage}
    \caption{YOUR FIGURE CAPTION}
    \label{YOUR_FIGURE_LABEL}
\end{figure}

Answer 4

Yet another option using TikZ:

\begin{figure}
  \centering
  \begin{tikzpicture}
    \node[draw] (fig) {
      \includegraphics[YOUR_SETTINGS_HERE]{figures_PAL}
    };
    \node [anchor=north east,color=darkgray,inner sep=0,xshift=-5pt,yshift=-3pt]
      at (fig.south east) {\footnotesize Source: YOUR_SOURCE};
  \end{tikzpicture}
  \caption{Simplest picture.}
\end{figure}

This will result in:

The benefit of this solution may be that you have to set the dimension only for the graphic. The position of the note follows automatically.

Btw: If the note shall be directly underneath the figure you can change anchor=northand the position at (fig.south).

Answer 5

Another option using the subcaption package

\documentclass{article}
\usepackage{subcaption}

\begin{document}

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

\end{document}
