Hello Looker community,
I am looking for help in producing a visualization that displays the Net Promoter Score for one of our digital properties.
In Looker, I have a column that, for each row, contains either “Detractor,” “Passive,” or “Promoter” as a value. I was able to use a table calculation to find the percentage of the total for each one of those categories. So in the “Results” section of “Data” tab in Edit Tile, there are three columns: the rating category, the total count per category, and the percentage of the total, with the second column hidden from the visualization.
Now I want to subtract the percentage of “Promoter” from “Detractor,” arriving at a final numerical value. But I can’t quite figure out how to create a table calculation that produces it.
