I am using the Tikz chronology package from Levi Wiseman. Specifically, I have used the code presented here and added some own commands in order to avoid rotation, etc. However, I would like to add vertical lines connecting each event date with the respective event tag, e.g. a line connecting "35" and "Clearing Shares". Your help is highly appreciated.

    I've never used chronology but I think there's something wrong in \begin{chronology}[7]{1}{42}{3ex}{\textwidth} because it doesn't compile for me. Is it correct? – Ignasi Feb 04 '15 at 10:28
  • Dear @Ignasi have you tried the example from (http://tex.stackexchange.com/questions/109382/chronology-adds-arbitrary-gaps)

    It uses more or less the same syntax, e.g. \begin{chronology}[5]{0}{30}{4ex}{\textwidth}

     – ScoobyDoo84 Feb 04 '15 at 10:35
  • I've tried now and it doesn't work although due to some other reasons. If Gonzalo's code works for you, forget my comments. – Ignasi Feb 04 '15 at 11:02
  • Let me know what is the exact error message, maybe I can help you. – ScoobyDoo84 Feb 04 '15 at 11:25

    I've found it, your example is missing all \renewenvironment{chronology} part from Gonzalo's code. May be you already integrated it inside chronology.sty, but MiKTEX didn't do it. Now your example works for me. – Ignasi Feb 04 '15 at 11:35
  • I added the \renewenvironment{chronology} part from Gonzalo's code to my orginial post. Hope that helps. – ScoobyDoo84 Feb 04 '15 at 11:46

With your code I could not get your results, so I've deleted all right=... nodes option in commands \agm, \action, ...

In \multirowevent, a command for drawing the vertical line between all events and date has been added.

\draw[->, shorten >=3pt] (auxnode.south) -- (\xstop,0);

You can adjust all parameters according your taste. The result looks like:

  • Dear Ignasi, thank you very much! Almost perfect. In case you know how to add a small white space between the \draw[->, shorten >=3pt] (auxnode.south) -- (\xstop,0); and the chronology, i.e. the timeline so that the arrow does not hit the timeline, please let me know. – ScoobyDoo84 Feb 04 '15 at 12:09

    @ScoobyDoo84, increase shorten value or change y component of destination end (\xstop, 0). – Ignasi Feb 04 '15 at 13:16
