[Tex/LaTex] Creating a timeline with chronology

chronology

I am trying to create a simple timeline with years underneath the line and some explaining text above each year. I understand that chronology is useful for this.

My problem is that when trying out examples from related questions (e.g. here or here), I always get the error "! Missing number, treated as zero."

A MWE (from the first related question linked to above):

\documentclass{article}
\usepackage{chronology}
\begin{document}
\begin{chronology}[3]{2011}{2016}{3ex}{\textwidth}
\end{chronology}
\end{document}

Which results in:

! Missing number, treated as zero. 
to be read again> 
} 
l.4 ...chronology}[3]{2011}{2016}{3ex}{\textwidth}
?

I have tried changing some of the values or removing them altogether, but this doesn't seem to help.

Has anyone encountered this problem or does anyone know of a solution? Chronology seems to be exactly what I need.

Removing the 3ex produces the following output without error:

Sample output

\documentclass{article}
\usepackage{chronology}
\begin{document}
\begin{chronology}[3]{2011}{2016}{\textwidth}
\end{chronology}
\end{document}
