* @brief
|
5
|
* The Timeline is an interactive visualization chart to visualize events in
|
6
|
* time, having a start and end date.
|
7
|
* You can freely move and zoom in the timeline by dragging
|
8
|
* and scrolling in the Timeline. Items are optionally dragable. The time
|
9
|
* scale on the axis is adjusted automatically, and supports scales ranging
|
10
|
* from milliseconds to years.
|
11
|
*
|
12
|
* Timeline is part of the CHAP Links library.
|
13
|
*
|
14
|
* Timeline is tested on Firefox 3.6, Safari 5.0, Chrome 6.0, Opera 10.6, and
|
15
|
* Internet Explorer 6+.

* Add zooming with pinching on Android
|
46

|
47
|
* Bug: when an item contains a javascript onclick or a link, this does not work
|
48
|
* when the item is not selected (when the item is being selected,

|
50
|
* Bug: when an item contains an image without size, or a css max-width, it is not sized correctly
|
51
|
* Bug: neglect items when they have no valid start/end, instead of throwing an error
|
52
|
* Bug: Pinching on ipad does not work very well, sometimes the page will zoom when pinching vertically
|
53
|
* Bug: cannot set max width for an item, like div.timeline-event-content {white-space: normal; max-width: 100px;}
|
54
|
* Bug on IE in Quirks mode. When you have groups, and delete an item, the groups become invisible
