Tikz 中的 \addmilestone 没有将里程碑放置在正确的位置

Question

不确定我是否理解正确，但保存年份的节点被命名为\timespan-\xi，其中\timespan是您在中定义的内容timespan={}（即在您的情况下为空），并且\xi是从 1 开始的计数器。因此，例如 1966 节点被称为-1，因此您可以将里程碑放在-1.south。我以前两个为例，但您可以自己填写其余部分。无论如何，我不知道您想如何放置文本：

您可能会注意到里程碑的圆圈并不完全位于年份的中心。造成这种情况的原因是节点文本中有一个明确的空格，正如您从以下几行中看到的那样98 和 102tikzlibrarytimeline.code.tex添加draw=white到节点选项演示了这一点：

但是，你可以修补\timeline宏以删除空格，使用

\usepackage{xpatch}
\xpatchcmd{\timeline}{\timespan\ \x}{\x}{}{}

对于颜色部分我没有答案。

应用补丁后的完整代码：

\documentclass[border=10pt]{standalone}
\usepackage{tikz}
\usetikzlibrary{timeline}
\usepackage{xpatch}
\xpatchcmd{\timeline}{\timespan\ \x}{\x}{}{}
\begin{document}

\begin{tikzpicture}[timespan={}]
% timespan={Day} -> now we have days as reference
% timespan={}    -> no label is displayed for the timespan
% default timespan is 'Week'

\timeline[custom interval=true]{1966, 1971, 1979, 1980, 1981,1986,1996,2001,2006,2011,2016}
% \timeline[custom interval=true]{3,...,9} -> i.e., from Day 3 to Day 9
% \timeline{8} -> i.e., from Week 1 to Week 8

% put here the phases
\begin{phases}
\initialphase{involvement degree=0cm,phase color=black}
\phase{between week=1 and 1 in 0.5,involvement degree=1.65cm}
\phase{between week=2 and 3 in 0.5,involvement degree=3.5cm}
\phase{between week=3 and 4 in 0.5,involvement degree=0cm}
\phase{between week=4 and 5 in 0.5,involvement degree=0cm}
\phase{between week=5 and 6 in 0.5,involvement degree=0}
\phase{between week=5 and 6 in 0.5,involvement degree=2.5cm} 
\phase{between week=6 and 7 in 0.5,involvement degree=1.9cm}
\phase{between week=7 and 8 in 0.5,involvement degree=3cm}
\phase{between week=8 and 9 in 0.5,involvement degree =1.7cm}
\end{phases}

% put here the milestones
\addmilestone{at=phase-0.270,direction=270:2cm,text={Obote/UPC win First Multiparty elections},text options={below}} %1962
\addmilestone{at=phase-1.110,direction=90:2cm,text={Obote attacks President Mutesa palace},text options={above}}
