I would to have a horizontal line below my figure caption. To this end, I used the following:
\DeclareCaptionFormat{myformat}{#1#2#3\hrulefill}
\captionsetup[figure]{format=myformat}
Then I obtain the following figure:
I only want the horizontal line below 'Figure 3.4', and not below my subcaption (a) and (b).
How do I remove the 2 horizontal lines under the subcaption?
You can use the caption package to define a new caption format incorporating the rule; something along these lines:
\documentclass{article}
\usepackage[demo]{graphicx}
\usepackage{caption}
\DeclareCaptionFormat{myformat}{#1#2#3\hrulefill}
\captionsetup[figure]{format=myformat}
\begin{document}
\begin{figure}[tb]
\centering
\includegraphics[width=\textwidth]{./fig/test}
\caption{`Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed
do eiusmod tempor incididunt ut labore et dolore magna aliqua.
Ut enim ad minim veniam, quis nostrud exercitation ullamco
laboris nisi ut aliquip ex ea commodo consequat. Duis aute
irure dolor in reprehenderit in voluptate velit esse cillum
dolore eu fugiat nulla pariatur. Excepteur sint occaecat
cupidatat non proident, sunt in culpa qui officia deserunt
mollit anim id est laborum`}
\label{fig:test}
\end{figure}
\end{document}
Here's the result:
I used the demo option for the graphicx package in order to make my example compilable for everyone; do not include that option in your actual code.
As mentioned in the comments, I don't think there's a way to change the caption position automatically. However, LaTeX provides two commands that can place the rule automatically for you: \topfigrule and \botfigrule. Here's an example, but as with Steven's solution, this still requires you to specify what placement the figure will be to get the caption correct. (Also, remember to makes sure your labels follow the caption command or are inside it.)
\documentclass{article}
\usepackage[demo]{graphicx}
\usepackage{caption}
\usepackage{lipsum}
\newcommand{\topfigrule}{\vspace{5pt} \hrule \vspace{-5pt}}
\newcommand{\botfigrule}{\vspace{-5pt} \hrule \vspace{5pt}}
\begin{document}
\lipsum[1]
\begin{figure}[t]
\centering
\includegraphics[width=\columnwidth]{blackbox}
\caption{This figure is on the top. The caption should be on the bottom,
and the horizontal line under it.}
\label{fig:1}
\end{figure}
\lipsum[1]
\begin{figure}[b]
\centering
\caption{This figure is on the bottom, so it caption is above it. Now
the horizontal line should be also above this text...}
\label{fig:2}
\includegraphics[width=\columnwidth]{blackbox}
\end{figure}
\lipsum[1]
\end{document}

Set an explicit format for the
subcaptions that doesn't usemyformat, butdefaultinstead:
