How to add multiple images in one place using captions like Figure x. a, Figure x.b?

Question

Is it possible to caption the two figures as Figure x.a, Figure x.b?

Answer 1

I think the subcaption package does what you are looking for. Here's a MWE:

\documentclass{article}
\usepackage{subcaption}

\DeclareCaptionSubType*{figure}
\captionsetup[subfigure]{labelformat=simple}

\begin{document}
\begin{figure}
\centering
\subcaptionbox{First letter}
[.4\linewidth]{\Huge A}
\subcaptionbox{Second letter}
[.4\linewidth]{\Huge B}
\caption{Two letters}\label{fig:letters}
\end{figure}
\end{document}

which produces the following output:

You can include a "graphic" (picture, etc.) by use of the graphicx package and then replacing \Huge A and \Huge B with the command \includegraphics{<filename>}.

Answer 2

You can use subfig package.

\begin{figure}
\centering
\subfloat[][\emph{Text one}.]
   {\includegraphics[width=.45\textwidth]{file1}} \quad
\subfloat[][\emph{Text 2}.]
   {\includegraphics[width=.45\textwidth]{file2}} \\
\subfloat[][\emph{Text 3}.]
   {\includegraphics[width=.45\textwidth]{file3}} \quad
\subfloat[][\emph{Text4}.]
   {\includegraphics[width=.45\textwidth]{file4}}
\caption{Textr.}
\label{fig:subfig}
\end{figure}

Answer 3

If you mean can you alter the format of how you can change a reference to "Figure 1.x" from "Figure 1x" you might like to check out the answer to a question I asked a while back (note the example shows how you do it both with the standard ref and cleveref

Is it possible to make a reference to a subfigure to appear Figure 2(a) with cleveref?
