Floats – How to Replicate Figure Without Inserting New Entry in List of Figures

captionsfloatstable of contents

I would like to replicate a figure in Chapter 3 within Chapter 6 such that the figure is displayed and optionally, it has the caption and Figure number of the figure in Chapter 3. If that is not possible, I would like to remove its entry from the List of Figures so that 2 of the same figures are not present.

For the latter I was able to find this: Removing captions but I suspect it will add the entry to the list of Figures. Is this achievable? Secondly, is this the preferred way of performing a replication?

Best Answer

I recommend to use the caption package. It provides a command \caption* which produces a caption without an entry in the list of figures.

Further I guess you probably don't like to number the figure, this is possible with \caption* as well. That's because a new and different number 6.x looks as odd as repeating the number 3.x within chapter 6.

Finally, I would use a reference to 3.x instead of replicating the picture.

You could use the tocloft package; an example:

\documentclass{book}
\usepackage{tocloft}

\newlength{\mylen}

\renewcommand{\cftfigpresnum}{\figurename\enspace}
\renewcommand{\cftfigaftersnum}{:}
\settowidth{\mylen}{\cftfigpresnum\cftfigaftersnum}
\addtolength{\cftfignumwidth}{\mylen}

\begin{document}

\listoffigures
\begin{figure}[!ht]
  \centering
  \rule{2cm}{2cm}
  \caption{test figure one}
  \label{fig:test1}
\end{figure}
\begin{figure}[!ht]
  \centering
  \rule{2cm}{2cm}
  \caption{test figure two}
  \label{fig:test2}
\end{figure}

\end{document}

If you want tocloft to use default LaTeX formatting (so it won't "mess up" for example the layout of your table of contents and so on) you can use the titles option of the package:

\usepackage[titles]{tocloft}

[Tex/LaTex] How to remove the caption and the figure x in the figure but to add the caption in the list of figures

You can use the macro \addcontentsline to add a list entry to the List of Figures (or others).

It takes three arguments:

the filename-extension of the list. (toc for Table of Contents, lof for Lists of Figures, lot for List of Tables, …)
the structure level
- toc: part, chapter, section, …
- lof: figure
- lot: table
the entry itself. Mostly it is preceeded by \protect\numberline{…} whose argument is the number for the entry and it aligns the following text.

My code provides two three commands:

\nocaption that adds only an caption text to the list,
\nocaptionbutnumber that adds additionally a number to the entry (that is incremented before, and
\nocaptionwithweirdalignment that doesn't use \numberline and therefore its entry text is aligned to the left (I wouldn't use it).

Minor Update

I've updated the answer so that the \addcontentsline macro doesn't have hard-coded first and second parameter. The commands should work now in table and other environment that define \@captype and the proper extension macro \ext@<\@captype>.

Code

\documentclass{article}
\makeatletter
\newcommand*{\nocaption}[1]{%
    \addcontentsline{\csname ext@\@captype\endcsname}{\@captype}{\protect\numberline{}#1}%
}
\newcommand*{\nocaptionbutnumber}[1]{%
    \refstepcounter{figure}%
    \addcontentsline{\csname ext@\@captype\endcsname}{\@captype}{\protect\numberline{\csname the\@captype\endcsname}#1}%%
}
\newcommand*{\nocaptionwithweirdalignment}[1]{%
    \addcontentsline{\csname ext@\@captype\endcsname}{\@captype}{#1}%
}
\makeatother
