Page Layout ⇒ Numbers overlapping Captions in LoF

[JohnR]

I am running into similar problems as described in this thread with the list of figures when using the amsbook class. I thought I could figure this out myself, but I do not understand many of the commands in the source code for the class.

I'd like to change the indentation of the text to be larger. Currently, I have over 10 figures in one chapter, and so, for example, when I have Figure 3.9, there is enough space for the caption, and it doesn't look weird. But when I have Figure 3.10, the caption text is right next to the figure number. I'd like to push all of the caption text to the right, but I do not know how to change it. Can anyone give some pointers or code? (preferably the last).

I found this post, but the solution does not work, I'm assuming because the TOC is set up differently in the amsbook class.

Your issue is not related at all to the problem described there. Therefore your question has been split to a new topic with a new title.

The problem is not comprehensible because amsbook doesn't number figures by chapter as you described.

Code: Select all

\documentclass[11pt]{amsbook}
\usepackage[T1]{fontenc}

\begin{document}
  \listoffigures

  \chapter{Foo}
  \setcounter{figure}{9}  % increment »figure« counter just to show the problem
  \begin{figure}[!htb]
    \rule{3.2in}{1.8in}
    \caption{Dummy figure}
    \label{fig:dummy}
  \end{figure}
\end{document}

Prepare a self-contained and minimal example that clearly reproduces the described issue to give an adequate problem description.


Remarks:

• Is there any special reason to use the amsbook class?

In page 11 of the AMS-LaTeX guide, it is suggested to insert the line

Code: Select all

\numberwithin{figure}{chapter}

in order to add the chapter number to the figure number. I suppose that is what JohnR did, so the figure numbering behaves as reported in the OP.

The following code solves the problem, I hope:

Code: Select all

\documentclass[11pt]{amsbook}
\usepackage[T1]{fontenc}
\numberwithin{figure}{chapter}
\makeatletter
\def\l@figure#1#2{\@tocline{0}{3pt plus2pt}{0pt}{2.5pc}{}{#1}{#2}}
\makeatother

\begin{document}
  \listoffigures

  \chapter{Foo}
  \setcounter{figure}{9}  % increment »figure« counter just to show the problem
  \begin{figure}[!htb]
    \rule{3.2in}{1.8in}
    \caption{Dummy figure}
    \label{fig:dummy}
  \end{figure}
\end{document}

Lines in the LoF are written by means of \l@figure, defined, in turn, in terms of the internal command \@tocline. The separation between the figure number and caption text is given by the fourth argument of \@tocline (by default, 1.5 pc). Above, in the definition of \l@figure, I've put 2.5pc instead. This value can be changed as needed.
