@flamber we must have different versions of metabase... I don't see the custom columns option on mine, just filter and summarize. (you can see it's Data, then filter, then summarize as opposed to yours which shows "custom column"):
I did try and go into the SQL, and I get close, but now I see that it's summing up the values, not counting the "rows":
What I'm trying to show is the number of shows/rows where the net was within each of those custom bins, however what I'm actually showing, is binning them appropriately, but visualizing the sum, vs the count.
I'm really wishing I'd taken some sort of SQL course
