Answer 1

In the histogram if you look clearly at the credits scale, the bars are corresponding to 4,8,12,14 and 18. There is equal spacing between 4 and 8, 8 and 12, but after 12 the next bar should be corresponding to 16 and the next to that would be 20. Therefore the spacing in credits scale is wrong.
