There is a hover effekt for the events that isn't shown on the screenshot.

===== FAQ =====
//[discussions should ideally be deleted and turned into FAQ entries along the way]//

- How do I get this working with Latex?  Installing the Latex plugin doesn't seem to be enough.

Hi, I get the following error everytime I save a page that contains a timeline:\\
Warning: Cannot modify header information - headers already sent by (output started at /var/www/abcd/http/wiki/lib/plugins/timeline2/syntax.php:1) in /var/www/abcd/http/wiki/inc/common.php on line 1543

After reloading  the page is fine and all changes are saved.
I run "Rincewind" on an debian Lenny. 
Any ideas on that?

Cheers, Thomas

===== Discussion =====

//Could be placed on an external page (e.g. plugin:pluginname:discussion) to have a distinction between user comments and author docs//

Much better then my own! 8-) , Wbr, Oleg Karachevtsev

:?: Question: is the plugin running well right now? I tried to install it but have problems which means that the charts are not displayed but rows of numbers (weeks)?
===== Proposal =====
I modified the code to allow for alternate date formats (see new constants) so that we in countries that insist on continuing to do things the nonsensical way can use this awesome plugin with m/d/Y.

<code php syntax.php>
