Subfigures within minipage

Question

I have 5 figures, which I want to display in one page, after dividing it in three minipages. Idellay I have 2 subfigures in the first minipage, 2 in the second one, and only one in the third minipage center-aligned.

I tried the following:

\documentclass[a4paper,10pt]{article}
\usepackage[demo]{graphicx}
\usepackage{subfigure}
\usepackage{amsmath}
\usepackage[paper=letterpaper,left=1.0in,right=1.0in,top=0.25in,bottom=1.0in,]{geometry}

\begin{document}

\begin{figure}
\begin{minipage}{03.\textheight}
\centering
\begin{subfigure}[a]{\includegraphics[width=.5\linewidth] {./pngs/profile_L_3lambda_max_1wl_0.png}
   \label{fig:subfig1}
 }%
\end{subfigure}
 \begin{subfigure}[b]{\includegraphics[width=.5\linewidth]{./pngs/profile_L_3lambda_max_1wl_dft_0.png}
   \label{fig:subfig2}
 }%
\end{subfigure}
\label{fig:myfigure}
\end{minipage}

\begin{minipage}{03.\textheight}
\centering
\begin{subfigure}[c]{\includegraphics[width=.5\linewidth] {./pngs/profile_L_3lambda_max_1wl_0.png}
   \label{fig:subfig1}
 }%
\end{subfigure}
 \begin{subfigure}[d]{\includegraphics[width=.5\linewidth]{./pngs/profile_L_3lambda_max_1wl_dft_0.png}
   \label{fig:subfig2}
 }%
\end{subfigure}
\label{fig:myfigure}
\end{minipage}

\begin{minipage}{03.\textheight}
\centering
\begin{subfigure}[f]{\includegraphics[width=\linewidth] {./pngs/profile_L_3lambda_max_1wl_0.png}
   \label{fig:subfig1}
 }%
\end{subfigure}
\caption{My caption}
\end{minipage}

\end{figure}

Unfortunately, the result is totally hopeless. Any suggestion on how to fix it? Thanks in advance

Answer 1

• the package subfigure is obsolete. it is replaced with subfig. however, even better is to use the subcaption package.

• i would not use minipage for grouping your sub figures, this can be done without them:

  \documentclass[a4paper,10pt]{article}
  \usepackage[demo]{graphicx}
  \usepackage{subcaption}
  \usepackage{amsmath}
  \usepackage[paper=letterpaper,
              left=1.0in,right=1.0in,
              top=0.25in,bottom=1.0in,]{geometry}
  
  \begin{document}
      \begin{figure}
  \centering
      \begin{subfigure}{0.45\linewidth}
  \includegraphics[width=\linewidth]{./pngs/profile_L_3lambda_max_1wl_0.png}
  \caption{}
  \label{fig:subfig1}
      \end{subfigure}\hfil
      \begin{subfigure}{0.45\linewidth}
  \includegraphics[width=\linewidth]{./pngs/profile_L_3lambda_max_1wl_dft_0.png}
  \caption{}
  \label{fig:subfig2}
      \end{subfigure}
  
  \smallskip
       \begin{subfigure}{0.45\linewidth}
  \includegraphics[width=\linewidth]{./pngs/profile_L_3lambda_max_1wl_0.png}
  \caption{}
  \label{fig:subfig3}
      \end{subfigure}\hfil
       \begin{subfigure}{0.45\linewidth}
  \includegraphics[width=\linewidth]{./pngs/profile_L_3lambda_max_1wl_dft_0.png}
  \caption{}
  \label{fig:subfig4}
      \end{subfigure}
  
  \smallskip
       \begin{subfigure}{0.45\linewidth}
  \includegraphics[width=\linewidth]{./pngs/profile_L_3lambda_max_1wl_0.png}
  \caption{}
  \label{fig:subfig5}
      \end{subfigure}
  
  \caption{My caption}
  \label{fig:my-figures}
      \end{figure}
  See Fig.~\ref{fig:my-figures}, particularly sub figure \ref{fig:subfig5} \dots
