I am using book class and I have an appendice section in \appendix :

\appendix
\include{annexes}

in this appendix I have several chapter and section of figures :

\chapter{Cartes et Plans}
\section{Ville}

\begin{figure}[ht] 
    \includegraphics{Figure 1.jpg}
    \caption{Figure 1}
\end{figure}
\begin{figure}[ht] 
    \includegraphics{Figure 1.jpg}
    \caption{Figure 2}
\end{figure}
\FloatBarrier


\section{Section}
\begin{figure}[ht] 
    \includegraphics{figure3.JPG}
    \caption{Figure 3}
\end{figure}

Currently my figures are numbered as follow :

A.1 Figure 1

A.2 Figure 2

A.3 Figure 3

I would like it to be

A.1.1 Figure 1

A.1.2 Figure 2

A.2.1 Figure 3

to match with the section/chapter numbering, does anyone know if there is an easy way to do that ?

Thanks a lot for your help and apologies if a similar topic has already been answered I couldn't find it

Cheers

Your original figure numbering - the default for book - is set via

\renewcommand{\thefigure}{\thechapter.\arabic{figure}}

which prints <chapter>.<figure>. Immediately after \appendix, you can issue

\renewcommand{\thefigure}{\thesection.\arabic{figure}}

which will print <chapter>.<section>.<figure> as the figure number.

Here's a complete example:

enter image description here

\documentclass{book}

\begin{document}


\chapter{A chapter}


\begin{figure}
  \caption{A regular figure}
\end{figure}


\appendix
\renewcommand{\thefigure}{\thesection.\arabic{figure}}


\chapter{An appendix chapter}


\section{First section}


\begin{figure}
  \caption{First figure}


\medskip


\caption{Second figure}
\end{figure}


\section{Next section}


\begin{figure}
  \caption{Final figure}
\end{figure}


\end{document}
