I want to put two figures side by side with their sub captions for my thesis. The template has the package \subfigure included, thus I cannot use for example \subcaption. If I use the following code:

\documentclass[a4paper, 11pt, oneside]{article}  
\usepackage[square, numbers, comma, sort&compress]{natbib} 
\usepackage{amsmath,graphicx,amssymb,braket,xcolor,subfigure,upgreek,bbold}

\usepackage{esint}

\begin{document}

\begin{figure}
\centering
 \begin{subfigure}[Fig.A]
     \centering
     \includegraphics[width=3cm]{Ex_Im.pdf}
     \label{fig:Ex_Im}
 \end{subfigure}
 \begin{subfigure}[Fig.B]
     \centering
     \includegraphics[width=6cm]{Ex_Im2.pdf}
     \label{fig:Ex_Im2}
 \end{subfigure}
\caption{This is the caption.}\label{fig:Label}
\end{figure}

\end{document}

I get the following figure:

enter image description here

If, on the contrary I use:

\begin{figure}
\centering
 \begin{subfigure}[Fig.A]
     \centering
     \includegraphics[width=3cm]{Ex_Im.pdf}
     \label{fig:Ex_Im}
     \caption{This is the caption A.}
 \end{subfigure}
 \begin{subfigure}[Fig.B]
     \centering
     \includegraphics[width=6cm]{Ex_Im2.pdf}
     \label{fig:Ex_Im2}
     \caption{This is the caption B.}
 \end{subfigure}
\caption{This is the caption.}\label{fig:Label}
\end{figure}

Then I get this:

enter image description here

So as you can there is no good result with either of those examples.

Thanks in advance for your help.

  • Done. Regarding the \subfigure, even if I don't include it in the \usepackage it tells me it is still there.

  • The syntax is completely wrong: with the subfigure package, there is a \subfigure command, not a subfigure environment.

1 Answer 1

The subfigure package provides a \subfigure command, not an environment.

The syntax is

\subfigure[<optional argument>]{mandatory argument}

what happens with your code is that the mandatory argument is \centering. Chaos ensues.

\documentclass[a4paper, 11pt, oneside]{report}
\usepackage[square, numbers, comma, sort&compress]{natbib}
\usepackage{amsmath,graphicx,amssymb,braket,xcolor,subfigure,upgreek,bbold}

\usepackage{esint}

\begin{document}

\begin{figure}
\centering

\subfigure[Fig.\ A]{\includegraphics[width=3cm]{example-image}\label{fig:Ex_Im}}
\subfigure[Fig.\ B]{\includegraphics[width=6cm]{example-image}\label{fig:Ex_Im2}}

\caption{This is the caption.}\label{fig:Label}
\end{figure}

\end{document}

However, subfigure is obsolete and you should prefer either subfig or subcaption.

With the former package, the syntax is

\documentclass[a4paper, 11pt, oneside]{report}
\usepackage[square, numbers, comma, sort&compress]{natbib}
\usepackage{amsmath,graphicx,amssymb,braket,xcolor,subfig,upgreek,bbold}

\usepackage{esint}

\begin{document}

\begin{figure}
\centering

\subfloat[Fig.\ A]{\includegraphics[width=3cm]{example-image}\label{fig:Ex_Im}}\quad
\subfloat[Fig.\ B]{\includegraphics[width=6cm]{example-image}\label{fig:Ex_Im2}}

\caption{This is the caption.}\label{fig:Label}
\end{figure}

\end{document}

With the latter, you can use \subcaptionbox:

\documentclass[a4paper, 11pt, oneside]{report}  
\usepackage[square, numbers, comma, sort&compress]{natbib} 
\usepackage{amsmath,graphicx,amssymb,braket,xcolor,subcaption,upgreek,bbold}

\usepackage{esint}

\begin{document}

\begin{figure}
\centering

\subcaptionbox{Fig.\ A\label{fig:Ex_Im}}{\includegraphics[width=3cm]{example-image}}\quad
\subcaptionbox{Fig.\ B\label{fig:Ex_Im2}}{\includegraphics[width=6cm]{example-image}}

\caption{This is the caption.}\label{fig:Label}
\end{figure}

\end{document}

I'd prefer subcaption, but the class you're using might not like it; in this case, go with subfig.

  • One small thing though. My (a) and (b) appear as (A) and (B). Any idea why that might occur?

  • @Kio No, if you don't point to a place where the Thesis class can be examined.

  • @Kio Sure, but if I can't see it, there's nothing I can say about the labels.
