I don't understand the subroutine that was posted earlier. I don't understand what I am supposed to pass to items?

A list of numbers from which you want to build your histogram. And it doesn't have to be sorted.

Your sample data generates this histogram for me: 

0: 67
30: 73
60: 93
90: 75
120: 26
150: 18
180: 10
210: 5
240: 2
270: 1
300: 1
330: 2
360: 1
390: 1
450: 1
840: 1
