Chart with number boolean

Hi  v-diye-msft 

Thank you, that's ok in this case.

In my case, i have two data sets :

- date table with a status open or not for each day

- data table which n lines for each month of each year.

I created a link between both tables in using date field.

I would like to know number of open days of year select by second tables.

The measure shows the number of open days of keys select

The easiest way is in adding a second date data set without link with data, but it's not correct for me to have two date calendars.

Ex Data table :

Thanks
