[Tex/LaTex] How to adjust the gap between figure and caption within the same subfloat

subfloats

My question is:

How to adjust the gap between figure and caption within the same subfloat

Not the gap between two subfloat.

For the following example:

\begin{figure}
    \centering
    \subfloat[A]{\includegraphics[ scale=0.5]{images/a.jpg}}
    \vspace{-10pt}
    \subfloat[B]{\includegraphics[scale=0.5]{images/b.jpg}}
    \vspace{-10pt}
    \caption{}\label{fig:online_test}
\end{figure}

I got the following figure:

The sub-caption of (a) is too close to the sub-figure B. I hope the caption (a) to stay closer to sub-figure A. How can I adjust the space between the caption and figure within a subfloat?

Thank you all for helping me and I would prefer a solution for subfloat, instead of using other packages. But I would also appreciate a solution of using other packages.

I know my question looks similar to this question. But please make it clear. I'm asking for how to adjust the gap between figure and caption within a subfloat, not the gap between two subfloat. That is, the gap between the caption "a" and the figure "A"

Thank you.

your have more problems:

with your code i can't reproduce provided images. they are in one line ...
problem is probably in images, which have white space below image. to check this, put image in \fbox{...} like

\subfloat[A]{\fbox{\includegraphics[scale=0.5]{images/a.jpg}}}

and see, if the frame is tied width image

other causes can be in your document preamble, which you not show. for example the following mwe

\documentclass{article}
\usepackage[demo]{graphicx}
\usepackage{subfig}
\usepackage[skip=1ex]{caption}

\begin{document}
\begin{figure}
    \centering
    \subfloat[A]{\fbox{\includegraphics[scale=0.5]{images/a.jpg}}}

    \subfloat[B]{\includegraphics[scale=0.5]{images/b.jpg}}
    \caption{}\label{fig:online_test}
\end{figure}
\end{document}

gives the following result:

distance between subfloat[...]{...} and caption is determined with option \package[skip=1ex]{caption}. this set vertical space determined by skip globally. if you like to change only for this image, than please add after \begin{figure}

\captionsetup{skip=<desired value}

Your have loaded the package caption incorrectly.

small, sc, bf, nooneline are not package options. You can use the font setting small, sc, bf with the package options font,labelfont and textfont.

An example:

\usepacakge[labelfont={bf,sc},texfont=small]{caption}

The option nooneline is no longer supported. Instead, use singlelinecheck=off. The documentation of caption listed such changes in the appendix.

The documentation can be found on your computer with

texdoc caption

or CTAN: caption on CTAN

In relation to you minimal example:

\documentclass[demo]{report}
\usepackage{graphicx}
\usepackage{subfig,float}
\usepackage[skip=5pt,font={bf,sc,small},singlelinecheck=off]{caption}
\captionsetup[subfloat]{captionskip=50pt}
\begin{document}
\begin{figure}
\centering
%%----start of first subfigure----
\subfloat[yyy]{
\label{subfig:a} %% label for first subfigure
\includegraphics[width=10cm]{fig1.eps}}\\[5pt]
%%----start of 2nd subfigure----
\subfloat[xxx]{
\label{subfig:b} %% label for third subfigure
\includegraphics[width=10cm]{fig2.eps}}
\caption{Cap}
\label{fig} %% label for entire figure
\end{figure}
\end{document}

[Tex/LaTex] Subfloat caption width requirements and alignment problems

Here are some suggestions to fix your current situation:

Note the subfloat notation:
```
\subfloat[<LoF>][<subcaption>]{<body>}
```
Since your <body> consisted only of a \label command, the <subcaption> (actually, the <LoF> entry) had to wrap around something that is "very thin", causing it to not typeset properly. See page 4 of the subfig documentation for an explanation of this.
Also, the \label should be included in the <body>.
If you put the entire \subfloat within a fixed-width environment, the caption will wrap according to that width. This can be achieved via a minipage environment, for example. In the following minimal example, I've defined two new commands:
```
\vertfig[<subcaption>]{<body>}% For vertical figure placement
\horizfig[<subcaption>]{<body>}% For horizontal figure placement
```
that you can use to replace the traditional \subfloat. \vertfig typesets its contents in a 5in-width minipage, while \horizfig does so in a 3in-width minipage. Both dropped the second optional argument of \subfloat[..][..]{...}, since it didn't seem to matter to you.

As you can see, no fixed-width \captionsetup is required, since the captions wrap to the box they're contained in.

Different subfloats with different widths

\documentclass[11pt]{article}
\usepackage[a3paper]{geometry}% http://ctan.org/pkg/geometry
\usepackage{graphicx}% http://ctan.org/pkg/graphicx
%\usepackage{caption}% http://ctan.org/pkg/caption
\usepackage{subfig}% http://ctan.org/pkg/subfig
\newsubfloat{figure}
\pagestyle{empty}% No header/footer
\newcommand{\vertfig}[2][]{%
  \begin{minipage}{5in}\subfloat[#1]{#2}\end{minipage}}
\newcommand{\horizfig}[2][]{%
  \begin{minipage}{3in}\subfloat[#1]{#2}\end{minipage}}
\begin{document}

\begin{figure}[ht]
  \centering
  \vertfig% \subfloat
    [This is probably the biggest tiger you will ever see in your life.
     The caption associated with this subfloat should span more than one
     line even though the width of the contents is 5in.]
    {\includegraphics[width=5in]{tiger}\label{fig:vizcardfront}}

  \vertfig% \subfloat
    [Data submission form on the back of the view guide.]
    {\includegraphics[width=5in]{tiger}\label{fig:vizcardback}}
  \caption{The visibility monitoring view guide.}\label{fig:viewcard}
\end{figure}

\begin{figure}[ht]
  \centering
  \horizfig%\subfloat
    [Here is another picture of the tiger, this time a little smaller.
     It is still very fierce-looking, right?]
    {\includegraphics[width=3in]{tiger}\label{fig:plantcam}}
  \hfill
  \horizfig%\subfloat
    [A HOBO$\textsuperscript{\textregistered}$ data logger for air and soil data.]
    {\includegraphics[width=3in]{tiger}\label{fig:logger}}
  \caption{Automatic data collection instruments.}\label{fig:autodata}
\end{figure}

\end{document}

geometry was merely used to set the paper size to a3paper.
