Aggregation within the count function

[#1]

Hello friends

For every Date I want count KPI_names where avg KPI_value by KPI_name <1 

i try this expression, but it doesnt work

= count ( {<aggr(avg(KPI_value), KPI_name) ={'<1'}>} distinct KPI_name)

Let me know if  anyone has idea or decision of this.

Thank you in advance
