Highlight color coded values using a marker

Hi, snaraya 

Thanks for letting us know your user experience.  According to your case description, I do understand how frustrated you are now.

Nevertheless, according to our measured results, I feel regretful to inform you that it turns out to be a by-design one.We currently can't modify the cell borders of a matrix visual based on a slicer's selection.

Of course, you can try to distinguish the Custom Visual Marketplace to see if it meets your needs.

If you feel that performance needs to be improved, you can also submit an idea on

https://ideas.fabric.microsoft.com/ and wait for users with the same needs as you to vote for you and help you realize the idea as soon as possible. Many features of our current products are designed and upgraded bed on customers’ feedback.  With requirements like this increase, the problem may well be released in the future.

Thanks for your understanding.

Best Regards,

Leroy Lu
