Hi Emma,

Thanks, data is OK. Most of it works as a charm with the code you shared in your post..

A comment to begin with. The 1000 rows correspond to 1000 accidents in the same day (May 17th 2016) all of them have the same cause "Unspecified'.It makes me wonder if this likely to occur in real life.

A few things do not work with my version of MMA (10.2):

Select[data, DateValue[#[["DATE"]], "Month"] == {4, 5} &] does not select anything although all rows are dated May 16th,2016. Quite puzzling. Related to the fact that the .m file has for date format DD MMM YY instead of something else to make the selection work ?

In Bar Chart # of Accidents per Borough, the name of the Borough is missing on the histogram x axis.

I noticed that the PieChart Collisions Sorted by Weekday, does not include the number of collisions in the slices (as in the previous PieChart.) Is it intended ?

That's all. Thank you again for your great post.

Hi Jan,

Attached to this reply is a shortened version of the data I used as a .m file. To retrieve it you can run Get to put the dataset into your notebook. Please let me know if this works for you.
