CONTROL CHARTS RULE VIOLATION, CONDITIONAL FORMATTING

I have one question i am working on statistic control chart dashboard ,where there are various rules violation. 

Suppose for example Rule 1 says if consecutive points are below zero sigma then it is violating rule 1.

I have successfully built all the rules and they are working fine. But the problem is whenever there is violation of rule 1, then at 8th point it is showing violation which is fine but i want to highlight 1 to 7 points along with 8th point so that it brings good user experience. 

To achieve that i have used dax measure but problem is measures are iterating row and i want result at column level. I also tried creating calculated column but it won't work. Is there any solution for it ?..
