Doesn't that code simply set the minimum date used by the timeline? I
don't think it will scroll the timeline. I think you want this:
tl.getBand(0).setCenterVisibleDate(tl.getBand(0).getMinDate());
Assumptions, before calling the above:
- 'tl' is the name of your timeline object
- tl is initialised
- event data is loaded
So, something like (code not tested) this in your start-up code:
//create the actual Timleine object
tl = Timeline.create(document.getElementById("tl"), bandInfos,
Timeline.HORIZONTAL);
// load the event data;
tl.loadXML("events.xml", function(xml, url)
{ eventSource.loadXML(xml, url); });
// get the first date
var minDate = tl.getBand(0).getMinDate()
// scroll to the first date
tl.getBand(0).setCenterVisibleDate(tl.getBand(0).getMinDate());
