Hi,

I have a list of students, with 3 columns:

- Name
- starting_date
- end_date

I would like to have a graph showing for every week of the year how
many students were there.

Can someone point me in the right direction to do this? Or send me a
sheet doing something equivalent.

My first guess was to build a sheet with very long formulas in each
cell, calculating with ifs the presence of each student. Maybe there
is an easier way.

Thanks a lot

François
