Estoy usando el timelinepaquete de Arne Meier y quiero controlar la altura de los conectores de la línea de tiempo, disponible enGitHub. Está disponible la opción de personalizar el color de los conectores de la línea de tiempo. Considere el siguiente código para componer la imagen adjunta:
\documentclass{article}
\usepackage{timeline}
\definecolor{Wyellow}{cmyk}{0.15,0.05,0.84,0}
\definecolor{WrandomI}{cmyk}{0.66,0.07,0.13,0.0}
\definecolor{WrandomII}{cmyk}{0.33,0.04,0.44,0.05}
\definecolor{WrandomIII}{cmyk}{0.55,0.15,0.54,0.0}
\definecolor{WrandomIV}{cmyk}{0.44,0.65,0.14,0.1}
\begin{document}
For changing the height of the timeline connectors by using the \verb|timeline| package.\\
\begin{timeline}[Wyellow][WrandomI][WrandomII][WrandomIII][WrandomIV] %where WrandomIV is the color of the timeline connectors.
\timebar[3]{|}{0}{2000}{2013}{1}{|}
\entry{2002}{entry}{no opacity}
\entryshift{2003}{entryshift}{no opacity}{4mm}
\flipentry{2004}{flipentry}{no opacity}
% \flipentry{2005}{Anotherflipentry}{no opacity}
% \flipentry{2005}{Anotherflipentry-I}{no opacity}
\flipentry{2005}{NoOverlapIsExpected}{no opacity}
\flipentryshift{2005}{flipentryshift}{no opacity}{4mm}
\entry[0.5]{2008}{entry}{opacity}
\entryshift[0.5]{2009}{entryshift}{opacity}{4mm}
\flipentry[0.5]{2010}{flipentry}{opacity}
\flipentryshift[0.2]{2011}{flipentryshift}{opacity}{4mm}
\end{timeline}
\end{document}
Lo que produce el siguiente resultado:
La expectativa es conseguir la línea de tiempo cuya imagen está escrita a mano:
Si es posible controlar la altura de los conectores de la línea de tiempo, se puede evitar la superposición. Los puntos (en la imagen escrita a mano como líneas conectoras) no tienen que ser puntos ya que las líneas conectoras representan la misma idea. El archivo de estilo utilizado para obtener la línea de tiempo es el siguiente:

El aspecto para etiquetar ambos lados (arriba y abajo) de la línea de tiempo ya está considerado; sin embargo, no está presente en la imagen escrita a mano. En cuanto a cambiar los ángulos de las etiquetas, se deben realizar cambios en el archivo de estilo.
La razón principal para publicar esta pregunta es obtener recomendaciones sobre cómo ajustar la altura de los conectores de la línea de tiempo para evitar etiquetas superpuestas (por ejemplo, al usar este paquete, no se pueden crear dos eventos para el mismo año en la misma posición). El paquete también tiene un manual que se puede compilar y el manual muestra un comando que parece ser el relevante; sin embargo, el uso de este comando para controlar la altura de las etiquetas aún no se ha completado:
\maxof{\heightof{#3}}{\heightof{#4}}+1.5mm
Se realizaron algunos cambios (como el uso de la ortografía de la palabra "conectores") en el timelinearchivo de estilo. timeline.stySe agradecerá cualquier sugerencia para modificar el archivo para obtener el resultado deseado.
¡Salud!
