我想生成一条时间线，但它从一年中的某个月份开始，而不仅仅是从一月开始。此外，时间线的结束时间应该可以修改，以便与十二月不同。我喜欢 chronosys 包，但这似乎不可能，因为在编译时它会出错，而当只指定年份时它会正常工作。
对于事件，也可以指定具体日期，但对于时间周期，这些时间周期总是跨越一整年，从 1 月到 12 月，而我只想指定几个月。我该如何实现这一点？
下面是有效代码和非有效代码，以显示我的目标：
\documentclass{beamer}
\usepackage{chronosys}
\begin{document}
% working
\catcode`\@=11
\def\chron@selectmonth#1{\ifcase#1\or January\or February\or
March\or April\or May\or June\or
July\or August\or September\or
October\or November\or December\fi}
\definechronoperiode{Leave}[color=red, textstyle=\it]
\begin{frame}
\frametitle{Time line}
\startchronology[startyear=2010,stopyear=2016]
\chronoLeave{2011}{2012}{Leave}
\chronoevent{1/10/2015}{test}
\endchronology
\end{frame}
% what I want -> not working
\begin{frame}
\frametitle{Time line}
\startchronology[startyear=01/10/2010,stopyear=01/10/2016]
\chronoLeave{10/10/2011}{16/01/2012}{Leave}
\chronoevent{1/10/2015}{test}
\endchronology
\end{frame}
\end{document}
答案1
chronos 的当前版本可在以下位置获得：
https://tex.stackexchange.com/a/342699/ （2016年12月6日）
这是我发布的代码的增强版本这个答案作为的替代chronosys，因为后者很难修改。
除了上面解释的按键之外，
event是一种用于一日活动的风格；event line是用于绘制这些事件的线条的样式；period是一种用于在时间线上绘制表示持续时间的线的样式；period event是一种用于较长活动的方式；period event line是用于绘制这些事件的线条的样式。
提供了两个新命令：
\chronosevent [<options for event line>] {<date>} [<options for event node>] {<text>} (<distance of event node from timeline>)\chronosperiod [<options for line marking period on timeline>] [<start date>] [<options for period event line>] {<end date>} [<options for period event node>] {<text>} (<distance of period event node from timeline>)
可选参数允许覆盖特定事件/时期事件的默认样式。
