Bar chart displays right side

[Kausha Mehta]

Hello,

I have the data in DB with date like "2015-11-25 13:14:28", "2015-11-01 13:14:59", "2015-12-02 06:05:55", "2015-12-01 06:05:55". When i'm trying to display month wise plot bar chart then it displays like attached image. I think the issue is when the data with end date of month then it displays right side.

Thanks!
