Hello @miguelfilho, welcome to the Quick Sight community !
What does your insight narrative look like? You’ll want to create two computations to manage the metrics that you would like to add to your insight visual.
The thing I was trying to do was:
Bring top3 best channel_names (categorys) based on the Impact on Tgt metric, while also showing the Rlz / Tgt metrics of those same 3 categorys.’
