This is a follow up to Variable expansion, quotes and equal sign.
Here is my data:
LOAD * INLINE [
If I want a dimension that is a list of all locations, I can either define it in the dimension: ='$(=Concat(location, ', '))'
Or I can create a variable SET vTest= =Concat(location, ', ') and the dimension defined as =vTest
Now, I want to limit how many locations I see to the top two. I know that I can use rank to limit my set like this: =if(aggr(rank(min(id)),location)<=2,location) , but I can't seem to find a way to combine this with Concat to use in a calculated dimension
The result I'm looking for is siteC, siteD. (Order is not important)
Also, is there a way to do this using set expression instead of if statement? My real data is very large and I expect performance will be an issue.
