I do not know how to remove the Chapter numbers in front of each chapter (Chapter #), and in the same time keep the section numbers. So I need something like the following:

Chapter name

1.1 First section

1.2 Second section

Also, numbering of my photos is a little weird. Right now, I have Photo 2.1 (since the photo is in Section 2). I just want normal numbering such as Photo 1, Photo 2 etc.

Thank you for your help!

  • Welcome to TeX.SX! This depends on the documentclass. One way, most likely, is to use \chapter*{Foo}, those are unnumbered. Having unnumbered chapters and numbered sections are a little bit weird, however, in my point of view

The easiest way is to set \thechapter to nothing, i.e. {}, but this will leave \thesection with a trailing . and the chapter heading will still show Chapter (or \chaptername).

To get a continous figure numbering, the figure counter has to be kicked out of the chapter reset list, i.e. use \counterwithout{figure}{chapter}. then.

Since the question is a little bit unclear, I don't change \@makechapterhead right now.

\documentclass{book}


\usepackage{chngcntr}%


\renewcommand{\thechapter}{}%
\renewcommand{\thesection}{\arabic{chapter}.\arabic{section}}%
\counterwithout{figure}{chapter}

\begin{document}
\tableofcontents
\listoffigures
\chapter{First chapter}

\section{First section}



\begin{figure}
\caption{Dummy figure}
\end{figure}

\chapter{Second chapter}

\section{First section in 2nd chapter}

\begin{figure}
\caption{Another dummy figure}
\end{figure}


\end{document}

  • You might use \renewcommand{\thesection}{\arabic{chapter}.\arabic{section}}% instead. Of course there remains the problem of \chaptername.

  • @Bernard: Well, this would leave the number of the chapter in the numbering. One could do this, if this is requested

    The O.P. seemed to request it, precisely.

  • @Bernard: You're right. I disregarded the list. Thanks, I will change.

Here is a way to do it with titlesec (albeit there seems to be some problem with the latest version: I wouldn't have done it exactly this way with the previous version of titlesec):

\documentclass{book}
\usepackage[utf8]{inputenc} \usepackage{titlesec}

\titleformat{\chapter}[block]{\bfseries\Huge}{}{0em}{}
\titleformat{\section}[hang]{\bfseries\Large}{}{1em}{\thesection\enspace}

\begin{document}
\tableofcontents
\listoffigures
\chapter{First chapter}

\section{First section}

\begin{figure}
\caption{Dummy figure}
\end{figure}

\end{document}

    \thesection seems to include the chapter numbers with it... Commented May 8, 2023 at 17:34
