something to tell me how many movies have i rated each day

So, i have stuff like this, movies that i've rated in several days:

6.11
6.11
7.11
9.11
11.11
12.11
12.11
12.11
13.11

As you could notice, 6 and 12 are there more than once = i rated more movies that day.
I need something to tell me how many movies have i rated each day (+ graph out of it)

EDIT: number of rated movies each day, actually NOT rating of the movies


If you dont understand anything then tell me and i will try to make it more comprehensible.
