Pivot table question

Hi, I have a tablet that looks like this:

<DATE><DOMAIN><Yes/NO>

I have created a pivot with the rows DOMAIN and the columns DATE. I then have these values:

the number of rows (count(something)

and the number of YES (sum of all 1)

It looks like this:

I would instead like to display the % of yes, and only the %.

For the life of me, I can't figure this out, any tips?
