Figure counter is not incrementing after use of paracol

Question

I am using one column environment to write text and put figures with their captions. At a certain point I had a longitudinal figure to integrate so I wanted to put its caption laterally by using paracol. Everything worked as expected, except that figure counter was not updated when I get back to one column environment.

Here is the minimal example:

\documentclass[a4paper,twoside,12pt]{report}
\usepackage[english]{babel} 
\usepackage{graphicx}
\usepackage{paracol}
\usepackage{verbatim}
\usepackage[nottoc, notlof, notlot]{tocbibind}

\begin{document}
\listoffigures
\begin{figure}[h!]
\centering
\LARGE{ONECOL}
\caption[onecol]{onecol}
\end{figure}

\begin{paracol}{2}
\begin{leftcolumn}
\centering
\LARGE{PARACOL}
\end{leftcolumn}
\begin{rightcolumn}
\begin{figure}
\caption[paracol]{paracol }
\end{figure}
\end{rightcolumn}
\end{paracol}

\begin{figure}[h!]
\centering
\LARGE{ONECOL}
\caption[onecol]{onecol}
\end{figure}
\end{document} 

Here is the output:

How could I fix that? Or is there another way to have the same output with well behaved figure counter incrementation?
Thank you

Answer 1

paracol explicitly defines all counters (except page counter) to be 'local' in columns, i.e. the values inside of paracol environment` are not transmitted to the outer document.

If this is not wanted, \globalcounter{figure} (for example) is to be used in the preamble of the file. (See section 5.3 of the current paracol manual for more information on this)

\documentclass[a4paper,twoside,12pt]{report}
\usepackage[english]{babel} 
\usepackage{graphicx}
\usepackage{paracol}
\usepackage{verbatim}
\usepackage[nottoc, notlof, notlot]{tocbibind}

\globalcounter{figure}

\begin{document}
\listoffigures
\begin{figure}[h!]
  \centering
  \LARGE{ONECOL}
  \caption[onecol]{onecol}
\end{figure}

\begin{paracol}{2}
  \begin{leftcolumn}
    \centering
    \LARGE{PARACOL}
  \end{leftcolumn}
  \begin{rightcolumn}
    \begin{figure}
      \caption[paracol]{paracol }
    \end{figure}
  \end{rightcolumn}
\end{paracol}

\begin{figure}[h!]
  \centering
  \LARGE{ONECOL}
  \caption[onecol]{onecol}
\end{figure}
\end{document}
