# How to place the chapter number behind the chapter title in KOMA script

I have the following layout for my chapter title and number:

I reached this using the following code:

\renewcommand*{\chapterformat}{%
\fontsize{60}{68}\selectfont\color{Gray}\thechapter\autodot\enskip}

\renewcommand*{\raggedsection}{\raggedleft}}


What is the best way to move the chapter number (2 in this case) to the right end of the same line, so that it overlaps with the chapter title? (I want the title to be on top). If possible, I want the method to integrate well with KOMA script, for example by redefining \chapterformat like I did above.

You mean like this?

That doesn't look good, does it?

At the very least, I would do something like this:

\renewcommand*{\chapterformat}{%
\rlap{\makebox[\linewidth][r]{\colorbox{ltGray}{\fontsize{60}{68}\selectfont\color{Gray}\thechapter\autodot}}}}

\renewcommand*{\raggedsection}{\raggedleft\rightskip1.2em\hfill}}

Hello Stephan, Thank's for the solution. The first example indeed doesn't look good, but at least I can experiment now to find something better looking. –  janoliver Apr 2 '12 at 14:28

Here is one way of obtaining the requested output via a patch of \@@makechapterhead (using etoolbox). \@@makechapterhead prints the actual chapter heading (chapter number + title) in scrbook.

\documentclass{scrbook}
\usepackage{xcolor}% http://ctan.org/pkg/xcolor
\usepackage{fix-cm}% http://ctan.org/pkg/fix-cm
\usepackage{etoolbox}% http://ctan.org/pkg/etoolbox

\renewcommand*{\chapterformat}{%
\fontsize{60}{68}\selectfont\color{black!50}\thechapter}% \autodot\enskip

\makeatletter
% Remove \chapterformat from \@@makechapterformat
{\chapterformat}% <search>
{}% <replace>
{}{}% <success><failure>
% Reinsert \chapterformat  modify heading layout
{\size@chapter{#1}}% <search>
{\ooalign{\hss\chapterformat\cr\size@chapter{#1}}}% <replace>
{}{}% <success><failure>
\makeatother


The first patch removes the typesetting of the chapter number (done via \chapterformat). The second patch re-inserts \chapterformat and overlays the title using \ooalign. For a quick course on \ooalign, see \subseteq + \circ as a single symbol ("open subset").
