Subfigure without figure

Question

I have two figures which I have already combined next to each other (horizontally) into one .eps figure via Stata. How do I now use the subfigure command to label both separately (horizontally). Leaving out the /includegraphics command twice within subfigure command (as I have already inserted the combined graph using includegraphics) does not give me the desired result. Is this not possible? Any work around?

\documentclass[11pt]{article}
\usepackage{setspace,graphicx,epstopdf,amsmath,amsfonts,amssymb,amsthm,versionPO}
\usepackage[utf8x]{inputenc}
\usepackage{graphicx}
\usepackage{epsfig}
\begin{figure}[htb]%
    \centering
    \includegraphics[width=7in]{Figure1.eps}
    \subfloat[label 1]%
    \qquad
    \subfloat[label 2]%
    \caption{2 Figures side by side}%
    \label{fig:example}%
\end{figure}

Answer 1

I would use the subcaption package and its \subcaption macro, as in the example below.

A couple of unrelated comments:

• it's not recommended to use utf8x for inputenc (utf8x vs. utf8 (inputenc)). I believe utf8became default last year, so if you have a new system then you don't need inputenc at all, but anyway prefer utf8 over utf8x if loading it.

• epsfig is just a wrapper over graphicx I believe, and today it's not needed at all. Remove that, and keep just graphicx.

\documentclass[11pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\usepackage{subcaption}

\begin{document}
\begin{figure}[htb]%
    \captionsetup[subfigure]{skip=10pt,position=bottom}
    \centering
    \includegraphics[width=\linewidth]{example-image-16x10}
    \parbox{0.45\linewidth}{\subcaption{First subfig}}\hfill
    \parbox{0.45\linewidth}{\subcaption{Second subfig}}
    \caption{2 Figures side by side}%
    \label{fig:example}%
\end{figure}
\end{document}
