Hi there!

I would like to add in my viz the average number of registrations per location.

For example, Ohio Dominican University in 2017 has Sum of Registration = 42

When you open the tooltip of that cell, you see that 42 is the sum of 2 sessions:

- July 11,2017: 23

- July 17,2017: 19

I would like to create the average per location and per year. So for example Average Reg in Ohio Dominican University in 2017 would be: (23+19)/2=21

Any idea how I can create this calculated field?

Thanks!
Pauline
