Change the caption name of a specific figure

Question

My question is very similar to this, However, I would like to only change the name of Caption for a specific figure, instead of all figures. Is it even possible and if so, then how?

Answer 1

IFF your document is really similar to the linked question, then you could do this:

\documentclass{article}

%\renewcommand{\figurename}{Fig.}

\usepackage[labelsep=endash]{caption}

\begin{document}

\begin{figure}
\centering
\rule{1cm}{1cm}
\caption{This is a figure}
\end{figure}

\begin{figure}
\renewcommand{\figurename}{Fig.}%
\centering
\rule{1cm}{1cm}
\caption{This is a figure}
\end{figure}

\begin{figure}
\centering
\rule{1cm}{1cm}
\caption{This is a figure}
\end{figure}

\end{document}

However, depending on what your real document looks like --- which is why an MWE is almost always advisable --- you may need to do something rather different.

Answer 2

This is more of an answer to a comment, but it was too long to write there. It is based on the code in jon's answer.

It creates a new counter. I am sure this can be done in one of the existing packages, but this works without any.

A new environment is created (figCaption), mostly not to keep writing the same thing for every figure. Within it, it just copies and replaces the existing counter for the figure, and resets it afterwards, so that the normal figure will keep counting Also, it replaces the figure-name, in the same way jon did, in his code.

Output

Code

\documentclass{article}

\usepackage[labelsep=endash]{caption}
\newcounter{Figcount}
\newcounter{tempFigure}
\newenvironment{figCaption}{%
    \renewcommand{\figurename}{Fig.}
    \setcounter{tempFigure}{\thefigure}
    \setcounter{figure}{\theFigcount}
    }{%
    \setcounter{figure}{\thetempFigure}
    \stepcounter{Figcount}
    }
\begin{document}

\begin{figure}
\centering
\rule{1cm}{1cm}
\caption{This is a figure}
\end{figure}

\begin{figure}
\begin{figCaption}
    \centering
    \rule{1cm}{1cm}
    \caption{This is a figure}
\end{figCaption}
\end{figure}

\begin{figure}
\centering
\rule{1cm}{1cm}
\caption{This is a figure}
\end{figure}

\begin{figure}
\begin{figCaption}
    \centering
    \rule{1cm}{1cm}
    \caption{This is a figure}
\end{figCaption}
\end{figure}

\begin{figure}
\centering
\rule{1cm}{1cm}
\caption{This is a figure}
\end{figure}

\end{document}
