Just in time for the hot weather . . . Aleks points me to this link to a graph of % check-ins at
NYC ice cream shops plotted against temperature in 2011. Aleks writes, “interesting how the ice cream response lags temperature in spring/fall
but during the summer, the response is immediate.”
This graph is a good starting point but I think more could be done, both in the analysis and purely in the graphics. Putting the two lines together like this with a fixed ratio is just too crude a tool. A series of graphs done just right could show a lot, I think!
