title: Several figures with one caption in a two-column Latex document
body: <p>What I want is
  <img src="https://i.stack.imgur.com/VCRmZ.png" alt="Screen"></p>
  
  <p>What I do is:</p>
  
  <pre><code>\begin{figure}[H]
  \makebox[\paperwidth]
  {
  \begin{subfigure}
  \includegraphics[width=0.4\paperwidth]{1.jpeg}
  \label{1}
  \end{subfigure}
  \begin{subfigure}
  \includegraphics[width=0.4\paperwidth]{2.jpeg}
  \label{2}
  \end{subfigure}
  } \par
  \makebox[\paperwidth]
  {
  \begin{subfigure}
  \includegraphics[width=0.4\paperwidth]{3.jpeg}
  \label{3}
  \end{subfigure}
  \begin{subfigure}
  \includegraphics[width=0.4\paperwidth]{4.jpeg}
  \label{4}
  \end{subfigure}
  } \par
  \caption{\label{pic-map} ...}
  \end{figure}

  <p>Box appeared to be the only solution to place these four images in two columns, but what happens now is that pictures are shifted and overlapping the second column and the caption remains in the first column:
  <img src="https://i.stack.imgur.com/6Xf4h.png" alt="Pictures are shifted and overlapping the second column and the caption remains in the first column"></p>
  
  <p>What could I do in such a situation?</p>
