This is because your series is not sorted by time. You have the following:

...
[Date.UTC(2014, 02, 7, 13, 14), 1351],
[Date.UTC(2014, 02, 7, 14, 03), 6391],
[Date.UTC(2014, 02, 7, 20, 02), 5231],
[Date.UTC(2014, 02, 7, 16, 28), 837],
[Date.UTC(2014, 02, 7, 17, 00), 541],
...

Sort all your data with ascending time scale.
