Hello
I have list of data (numbers) over time (days) for several groups. I need to calculate the cummulative data of each group by time for every day. In mpython, I get the result that way after sorting it:
data_sorted['cum'] = data_sorted.groupby(['group'])['data'].cumsum()
How can I get it in excel. Didn't succeed to overcome the long list
Thanks
Hi Bruno,
Sounds like a job for a pivot table. Please supply your workbook with the data.

Quick response.. Thanks.
Actualy, I succeded to get it with pivot table but I need to perform additional maths based on the results. I didn't succeed to take the results table back to the original one neither.
I attach the blog01-1 simplified example with the cummulative I calculated (easy to do for some rows only) and an example of math I need to add "[%] of cases". I have some more statistics like that to perform. The yellow are the data I have and the blue are calculated columns.
It is possible ?
