Help with Histograms alignment!

[simplename]

I've used the chart generator to generate a histogram but its alignment is all wrong.
say if at x=0, y=9 and somewhere further down, x = 6, y=3, the left side of a y=9 bar starts off having at 0 with width more than 0.5 (and the scale goes up by 0.5 both x and y) , this keeps going off until at the right hand side the left side of the x=6 bar starts off at like 5.4 or so! Just all the alignments went weird!
