Slicing and dicing NYC Noise: 2004 to 2017, complaints aggregated by day and week

Number of service requests to NYC’s 311 from 2004 to 2017: 26.99 million

Two graphs of a total 3.3 million noise complaints to 311: the first one is a plot of the number of noise complaints filed per day from 2004 to 2017.  The second is a similar aggregation but by number of complaints per week. Anything strike you as odd in either?
