[Tex/LaTex] Disable caption of subfigure completely

captionsspacingsubcaption

I use the caption and subcaption packages to set up my figures. Sometimes I don't want to display any (sub-) captions at all.

I tried \captionsetup[subfigure]{labelformat=empty} with an empty caption (\caption{}) which works, but the problem is, that the vertical space between the main-caption and the images is now too big, because the space for the sub-captions is still "reserved".

How do I fix this? I have a feeling it might be possible with the \DeclareCaption-Format command of the caption package, but I don't know how.

\documentclass{article}
\usepackage[list=false]{subcaption}
\usepackage{caption}
\usepackage[final]{graphicx}
\begin{document}
\begin{figure}
\centering
\begin{subfigure}[b]{0.34\textwidth}    
\includegraphics[width=\textwidth]{example-image}   
\caption{}  
\end{subfigure}
\begin{subfigure}[b]{0.34\textwidth}
\includegraphics[width=\textwidth]{example-image}
\caption{}
\end{subfigure}
\caption{With caption labels enabled.}
\end{figure}
\begin{figure}
\centering
\captionsetup[subfigure]{labelformat=empty}
\begin{subfigure}[b]{0.34\textwidth}    
\includegraphics[width=\textwidth]{example-image}   
\caption{}  
\end{subfigure}
\begin{subfigure}[b]{0.34\textwidth}
\includegraphics[width=\textwidth]{example-image}
\caption{}
\end{subfigure}
\caption{With Subcaptions disabled. Spacing looks bad.}
\end{figure}
\end{document}

According to Zarko, you must delete the extraneous empty caption{} where you dont want to have neither caption nor space (ie on line 23 and 27). By this way your\captionsetup[subfigure]{labelformat=empty} is not needed.

The more elaborate suggestion of Bernard dont resolve the problem without removing the unwanted caption{}, as some extra space is still added.

[Tex/LaTex] custom sub-caption and refs format for subfigures

I don't think using three different formats for the numbering of subfigures is good. Anyway, here it is:

\documentclass{article}
\usepackage{caption}
\captionsetup[figure]{labelsep=period,justification=centering,singlelinecheck=off}
\DeclareCaptionLabelFormat{rightparen}{#2)}
\usepackage{subfig}
\captionsetup[subfloat]{labelformat=rightparen}
\showcaptionsetup[uniq]{subfloat}
\usepackage{xparse}

\ExplSyntaxOn
\seq_new:N \g_akj_subfloat_seq
\NewDocumentCommand{\xsubfloat}{ m m }
 {
  \akj_subfloat:nn { #1 } { #2 }
 }
\NewDocumentCommand{\makexcaption}{o}
 {
  \caption{\IfNoValueF{#1}{#1~}Subfigures:~%
  \seq_use:Nnnn \g_akj_subfloat_seq {;~} {;~} {;~}}
 }
\cs_new_protected:Npn \akj_subfloat:nn #1 #2
 {
  % initialize
  \int_compare:nT { \value{subfigure} = 0 }
   { \seq_gclear:N \g_akj_subfloat_seq }
  % do the subfloat
  \subfloat[]{#2}
  % store the subcaption
  \seq_gput_right:Nx \g_akj_subfloat_seq { (\exp_not:N\textit{\alph{subfigure}}) ~ \exp_not:n { #1 } }
 }
\ExplSyntaxOff
\renewcommand{\thesubfigure}{\textit{\alph{subfigure}}}
\makeatletter
\def\p@subfigure{\thefigure\,}
\makeatother

\begin{document}
\begin{figure}
\centering
\xsubfloat{subfigure A}{%
  \rule{100pt}{50pt}%
  \label{fig:subfig-a}%
}
\xsubfloat{subfigure B}{%
  \rule{100pt}{50pt}%
  \label{fig:subfig-b}%
}
\xsubfloat{subfigure C}{%
  \rule{100pt}{50pt}%
  \label{fig:subfig-c}%
}
\makexcaption\label{fig:figures}
\end{figure}

See Figures~\ref{fig:subfig-a}, \ref{fig:subfig-b} and~\ref{fig:subfig-c}.
\end{document}

The \makexcaption command has also an optional argument for text going before the list of subcaptions, so

\makexcaption[Some text.]

would produce

Figure 1. Some text. Subfigures: (a) subfigure A; (b) subfigure B; (c) subfigure C

Beware of unprotected end-of-lines in the arguments of \subfloat, that are the cause of your spurious spaces.

[Tex/LaTex] subcaption/subfigure not centered, and caption too narrow

You have defined your subfigure environments to have a width of .3\textwidth, but your images are wider than that, so they will stick out on the right side. This is also the reason the captions are narrow, as they have the same width as the subfigures. So to fix this, just increase the width. You can use \columnwidth to make them as wide as the columns.

See the below code for an example, where I also added an \fbox around the each subfigure, so their boundaries are obvious.

\documentclass{article}
\usepackage{graphicx}
\usepackage{subcaption}
\begin{document}
\begin{figure}
        \centering
        % this is wide enough
        \fbox{\begin{subfigure}[b]{\textwidth}
        \centering
                \includegraphics[width=7cm,clip=false]{example-image-a}
                \caption{Some long caption some long caption some long caption}
        \end{subfigure}}

        % this has a too narrow subfigure
        \fbox{\begin{subfigure}[b]{0.3\textwidth}
                \includegraphics[width=7cm,clip=false]{example-image-b}
                \caption{Some long caption some long caption some long caption}
        \end{subfigure}}
        \caption{Label predictions using cross-correlation-, GTW-, and LSTM-based classifiers}
\end{figure}
\end{document}
