here's screenshot of data through ajax request , assign above variables.

here's plunker http://plnkr.co/edit/aysgpk9eq84l55t5rogq?p=preview

the datapoint tooltip in image on thursday, @ 2 pm:

(new date(1437660070000)).toutcstring() "thu, 23 jul 2015 14:01:10 gmt" 

so nearer friday tick on axis thursday tick (the ticks @ midnight).

if day important graph can change timestamps @ midnight , align ticks on axis. do this, can use code this:

for (var = 0; < issued.length; i++) {     issued[i][0] = issued[i][0] - (issued[i][0] % 86400000); } 

see updated plunker.
