Aggregation with Fractile in Chart Expression not working

[joybratas1]

Hi Community, 

I have been struggling in creating a logic for my table as well as Map expression. 

My expression looks somewhat like

sum(aggr({index= {"<=$(vIndex) >"} Fractile(hours, 0.95) ,index)) 

My aim is to sum the 95th percentile hours for each index that is greater than (vIndex) 

But this don't work. 

Please help me in this.

The right format for your expression is: sum(aggr(Fractile({<index= {"<=$(vIndex)"}>} hours, 0.95) ,index))
