Multiple fillups per day - graph order

[Davek]

Just took a road trip (on 10/23) where I filled multiple times on one day. I noticed on the graph that while the fills for the day are both listed, they are in reverse order. The 'View all fillups' page lists the fills with the correct time of day, but when the graph is constructed the time of day information does not appear to be used to order the fills within each day.
