Timeline .addTrack method?


I wondered whether any documentation is available for the timeline.addTrack method, please?

I am trying to add another track and although there is a hint of it at the bottom of the screen, I need to raise the default timeline and track to make the latter visible.

viewer.timeline.addTrack(new Cesium.TimeInterval(
start : Cesium.JulianDate.fromIso8601(‘2005-11-22T00:30:36.750Z’),
stop : Cesium.JulianDate.fromIso8601(‘2005-11-22T00:58:46.750Z’)

Hi Hugh,

The Timeline.addTrack function is not part of the public API, so we can’t guarantee it’s usage will stay consistent from release to release.

Look at the source code, particularly Timeline._makeTicks, to see how the tracks are added and styled. You’ll probably need to modify the CSS to get the effect you’re looking to accomplish.



Thanks Gabby. :wink:
