Hello Everyone. Can anyone please help me on how to calculate the percentage for the sum/count.

As you can see on the left which is my souce data and on the right you can see the visulaization.

When i selected for a day (Day 1) i got NO as 1 and Yes as 1 and total is 2, which is good and now i aslo want to show the percentage next to them or in another serperate multi row card as NO 50% and YES as 50%.

when i select day 2 it is showing NO as 2 and now i want to show the percentage as NO 100%.
