order of dates

[jaygray0919]

When using Kubrick films, for example, the date order is oldest-to-newest.
How can I change the order from newest-to-oldest?
I see where the date is calculated
var timestamps = events.map(function(d){return d.value});
but do not see/know how to change the type of ordering (i.e. newest-to-oldest).
Thanks for assistance here.
