The idea of a 'track' in Timeline is an abstract one - there is no DOM element representing a track, so there is no individual track background to color or style. Also, remember that Timeline's default painting strategy is to put things on different tracks to avoid overlapping labels/icons/bars. If your events/labels get too close, the painter might need an extra track to avoid overlapping.
One approach that might work would be to use custom background styles for your bands. If you are running on modern browsers, you can easily add gradient styles to a band <div> that exactly matches the height of your track sets. Another approach would be to write a custom painter that does the grouping as you suggest, though this would involve a fair bit of javascript to implement. I've solved this requirement by using multiple bands, one for each category of event I need to display. Each band can use as many tracks as it needs to display its member events. I define a filter function for each band that only adds those events that belong to that band into the band's EventSource. --Mike On Aug 31, 2011, at 3:24 PM, aaron robb wrote: > Hello! > > What I want to do is figure out a way to group tracks, probably by > highlighting or changing the background for set tracks. > > For example, say I want to make 'trackNum's 1-8 one color, 9-16 > another, etc. > > How would I do this? > > > Or if there is another solution, what I want to do is show grouped > events.
