I´m trying to follow the documentation of chronosys LaTeX package, to solve my issue to avoid vertical straight to overlap the others labels, but I cannot go ahead!
My code in LaTeX is:
\documentclass[a4paper,12pt]{article}
\usepackage{chronology}
\usepackage{chronosys}
\begin{document}
\startchronology[startyear=1980]
\chronoevent{1982}{\rotatebox{90}{\textbf{ARCH} $\Rightarrow$ \newline Robert Engle~\cite{engle}}}
\chronoevent[markdepth=50pt, ifcolorbox = true, colorbox = white]{1986}{\rotatebox{90}{\textbf{GARCH} $\Rightarrow$ \textit{Tim Bollerslev}~\cite{bollerslev}}}
\chronoevent[markdepth=250pt]{1986}{\rotatebox{90}{\textbf{IGARCH} $\Rightarrow$ \textit{Tim Bollerslev e R. Engle}~\cite{englebollerslev}}}
\stopchronology
\end{document}
That is the result:
I tryed to insert colorbox=white, but I don´t know if I am is in the correct way...
