* @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+.

* 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,

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;}

* Bug on IE in Quirks mode. When you have groups, and delete an item, the groups become invisible
