# Change label numbering prefix

I want to change the labeling of my figures from A.1, A.2, ... to Abb. 1, Abb. 2, ..., because my appendix chapter is already labeled with A and this causes some confusion (whether A.1 is meaning the first section of the appendix or the first image).
I know I can change the label caption like this:

\addto\captionsngerman{
\renewcommand{\figurename}{Abb.}
}


from here, but this isn't what I want, because it just changes Abbildung A.1 to Abb. A.1. How can I change the prefix of the number?

• what is the class you use? – touhami Mar 18 '16 at 8:37
• I'm using babel with ngerman, graphicx and subfigure but I don't know if this is what you mean – TheFlow0360 Mar 18 '16 at 8:39
• 1) I mean \documentclass{....} 2) how do you want figure B.1 B.2 ... and C.1 C.2 to appear ? – touhami Mar 18 '16 at 8:42
• i use a custom one, \documentclass[german]{tex/ttthesis} (Thomas Thüm - Template for Theses from here). I didn't know I could get B or C, what results in a change of the prefix? i thought it's A because the word ist Abbildung – TheFlow0360 Mar 18 '16 at 9:02
• try \renewcommand\thefigure{Abb. \arabic{figure}} – touhami Mar 18 '16 at 9:32

The class used here is based on book.cls weach define figure by

\newcounter{figure}[chapter]


so it will be reset with chapter. To make it independent of chapter we use chngcntr package and its \counterwithout command.

Exemple: here we use itonly for appendix figure. If we want this for all document we use \counterwithout{figure}{chapter} in the preambl.

\documentclass{book}

\usepackage{chngcntr}

\begin{document}
\chapter{Foo}
\begin{figure}
\rule{4cm}{1cm}
\caption{Figure}
\end{figure}
\chapter{Bla}
\begin{figure}
\rule{4cm}{1cm}
\caption{Figure}
\end{figure}

\appendix

\counterwithout{figure}{chapter}
\setcounter{figure}{0}

\chapter{Foo}
\begin{figure}
\rule{4cm}{1cm}
\caption{Figure}
\end{figure}
\chapter{Bla}
\begin{figure}
\rule{4cm}{1cm}
\caption{Figure}
\end{figure}
\end{document}
