Group X Axis Labels based on Y axis Value

Hello All,

I need assistance on the following requirement.

Below is the chart where Count is being displayed on a company level.

My requirement is to group X axis company names having less than 6 count as others..

Also, Dynamically everytime when the chart is filtered, anything below 6 count should be grouped as Others on the X Axis.

Tq ..
