# How to create a timeline with references instead of dates?

I would like to insert a timeline into my thesis and replace dates by references to the lines of an interview such as : (l. 5-25) (l. is for line). I found an example of timeline that is quite what I'm looking for. But how can I replace years by references ? This is below that mwe I found here :

\documentclass[10pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{chronosys}
\usepackage{geometry}

\begin{document}

\startchronology[startyear=-3000,stopyear=-2000, startdate=false, color=blue!40, stopdate=false, arrow=true, height=3pt]
\setupchronoevent{textstyle=\scriptsize,datestyle=\scriptsize}
\chronoevent[markdepth=60pt]{-2080}{IM15 (C)}
\chronoevent[markdepth=-80pt]{-2115}{IM13 (C)}
\chronoevent[markdepth=20pt]{-2115}{IM26 (B)}
\chronoevent[markdepth=100pt]{-2170}{IM20 (B)}
\chronoevent[markdepth=-120pt]{-2190}{IIIM76 (E)}
\chronoevent[markdepth=70pt]{-2200}{IIIM353 (C)}
\chronoevent[markdepth=30pt]{-2245}{IIM69 (C)}
\chronoevent[markdepth=-70pt]{-2250}{IIM281 (C)}
\chronoevent[markdepth=-50pt]{-2145}{IM10 (B)}
\chronoevent[markdepth=-30pt]{-2240}{IIM163 (C)}
\chronoevent[markdepth=-70pt]{-2475}{IM90 (C)}
\chronoevent[markdepth=20pt]{-2480}{IM90 (B)}
\chronoevent[markdepth=-20pt]{-2500}{IIM63 (C)}
\chronoevent[markdepth=70pt]{-2550}{IM21 (A)}
\chronoevent[markdepth=-50pt]{-2570}{IM163 (B)}
\chronoevent[markdepth=30pt]{-2620}{IIM13 (C)}
\chronoevent[markdepth=-40pt]{-2690}{IM5 (B)}
\chronoevent[markdepth=40pt]{-2760}{IM130 (B)}
\chronoevent[markdepth=-15pt]{-2770}{IM65 (C)}
\chronoevent{-2935}{IM157 (B)}
\stopchronology
\end{document}

• I just found this example and it would be perfect if only I could use it. It's a vertical timeline : tex.stackexchange.com/questions/52394/…

• In what sense is it a timeline exactly? This would make more sense to me if you wanted to use, say, seconds or minutes into an interview: then it would be time. But how does time relate to lines of the interview exactly?

• @cfr It is not exactly a timeline since I refer to words and lines. I would like to show something like an alternating between some sections of a discourse and, in this case, the principle of a timeline is appropriate.

What you want here is not really a timeline as such. But maybe something like the following could be the basis for a solution.

\documentclass[border=10pt,tikz]{standalone}
\usetikzlibrary{arrows.meta,positioning}
\newlength\interviewunit
\tikzset{%
interview line/.code={%
\tikzset{interview/.cd, #1}
\pgfmathsetlength\interviewunit{(\interviewtotht-10mm)/\interviewlines}
\draw [interview/line] (0,5mm) coordinate (interview start) -- +(0,{-\interviewtotht-5mm}) coordinate (interview end);
},
interview/.search also={/tikz},
interview/.cd,
total height/.store in=\interviewtotht,
total height=100mm,
lines/.store in=\interviewlines,
lines=100,
line/.style={thick, gray, {Circle}-{Latex}},
mark/.style={gray,fill},
}
\newcommand*\interviewmarker[3][0pt]{%
\draw [interview/mark] (0,{-\interviewunit*#2}) circle (1.5pt) -- +(35mm,#1) circle (1.5pt) coordinate (interview mark);
\node [right=2.5mm of interview mark, anchor=west, align=left]  {l.~#2: #3};
}
\begin{document}
\begin{tikzpicture}
[
interview line,
]
\interviewmarker{34}{Take a break!}
\interviewmarker{0}{Start}
\interviewmarker[-10pt]{1}{Meet \& greet.}
\interviewmarker{75}{Phone rings.}
\interviewmarker{100}{End}
\interviewmarker{64}{Switch on lights.}
\end{tikzpicture}
\end{document}


• This mwe is nearly what I am looking for. I need to have a "timeline" that begins at line 1 and ends to line 58. Between those two points, I have several lines to mark : l. 1-10, l. 11-28, and so on.

• lines=100 is just an example. Use lines=58 if you have 58 lines. Similarly, change 100mm if you want a taller or shorter diagram. I don't know how a range should look as the examples you linked/posted don't seem to cover it. (Other timeline examples do, but tend to look a bit different.)
