Unfortunately, no. But in future versions of Timeline, we'll support
vertical scrolling. You can see the development version of that feature here
http://simile-widgets.googlecode.com/svn/timeline/trunk/src/webapp/examples/compact-painter/compact-painter.html

Assuming that you're using the latest version of Exhibit, take a look at
the timeline view's implementation
http://api.simile-widgets.org/exhibit/2.2.0/extensions/time/scripts/timeline-view.js
Look for
Exhibit.TimelineView.prototype._reconstruct
This function is called whenever the timeline needs to be updated. You
could make a copy of it after including all exhibit's code (so that your
copy overrides the default implementation) and modify the copy to do
what you want. More specifically, after this chunk of code
if (plottableSize > this._largestSize) {
this._largestSize = plottableSize;
this._reconstructTimeline(events);
} else {
this._eventSource.addMany(events);
}
the timeline should have laid out itself. Then you can get the number of
track and resize the timeline:
var trackCount = this._timeline.getBand(0)._tracks.length;
this._dom.plotContainer.style.height = ... some expression here,
ending with px ...
this._timeline.layout();
