Hi , @Anonymous 

According to your description, you want to show the top 10 data in your table. Right?

Here are the steps you can refer to :
(1)For your data have repeat data , and when you put data in the table visual , it will be deduplicated.

So we need to add an index column in Power Query Editor:

(2)For your need , you want to use a measure to filter the table . RIght?

We need to create a measure like this:

Flag = 
var _topn = TOPN(10 , ALLSELECTED('Table'))
var _showindex = SELECTCOLUMNS(_topn,"index",[Index])
var _curindex = MAX('Table'[Index])
return
IF(_curindex in _showindex ,1,0)

(3)Then we need to put the field we need on the visual and we can meet your need:

(4)For this we can also use "What-if" parameter as a sliver to replace the "10" in our measure.

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI!

@Anonymous You could create a Rank Column like below and filter for <= 10

Rank Column = RANKX('Table',[Count],,DESC)
