These plots show the volume of complaints over time, by moth, in Gowanus and Brooklyn respectively from 2010 to Dec 2017. Notice that the general trends of the rolling means follow roughly the same pattern, steadily increasing as time goes on. The Brooklyn plot appears to have more regular seasonality, while the Gowanus plot has a few interesting spikes that may be interesting in spring/summer of 2014. In 2017, there's another spike in the winter that doesn't seem to be reflected in the overall Brooklyn plot.
