Bubble Chart show Top N

What is the problem or goal the end user is trying to solve or accomplish?

Bubble chart has a tendency to have a lot of bubbles being shown and user is looking to have the control to show Top N of the Bubble Chart

How are they solving it currently?

Series Limit will work to limit it but there is no option to order the result, hence making this only limiting but not showing Top N.
The other option is to create a virtual dataset to precalculate and do a order by and limit in the SQL

Ability to choose Top N from chart customization
