Count when date is missing equal to 0

Hello,

Hope you are doing well.

It's my first time here.

So, I have a table like that called "Example"

And i would like to count the number of B for each day between the min date and the max date (so here between 01/01/2000 and 07/01/2000 but it must work for future date like 08/01/2000 etc...)

So for the missing date 02/01/2000 the count of "B" should be 0, for 01/01/2000 and 06/01/2000 should be 0 as well.

I got this line chart :

But i want to obtain this line chart :

Hope you can help me.

Thanks in advance!
