我使用優秀的chronosys。由於某種原因，我所有的彩色圖表都變成了黑色。經過長時間的調試練習後，我將其追溯到 xcolor 套件中使用 HTML 作為模型。
我是不是很傻，是否有錯誤，或者我應該避免添加 HTML 選項（我知道這裡不是真正的顏色模型）。其他一切的顏色不受影響。

答案1
目前版本的 chronos 可在以下位置取得：
https://tex.stackexchange.com/a/342699/ (2016-12-06)
我有一個替代方案chronosys，我曾經用它來回答其他一些問題。這是將其用於時間軸的第一步。
\begin{tikzpicture}
[
chronos={%
timeline width=120mm,
timeline height=5mm,
start date=0-01-01,
end date=2016-12-31,
only years,
timeline no years,
period event line/.style={draw=none},
timeline line={shorten >=-20mm, -{Triangle Cap[length=20mm]}}
}
]
\chronosperiod [draw=red]{1000}{1999}{2\textsuperscript{nd} Millennium}(-2.5pt)
\chronosperiod [draw=green]{192}{476}{Eastern Roman Empire}(-2.5pt)
\chronosevent {1969}{steps on the Moon}
\end{tikzpicture}
產生
這不會產生相同的輸出，但可以進行調整以適應。 （事實上，它比現在要靈活得多chronosys，呃，好吧……程式碼既不像人們希望的那樣易於理解，也不具有適應性。）
