Hi, in Experiment Results with Date dimension, if there are no conversions per variation at a particular date, the query fails to count the number of users in the variation. I see this behavior in a low-traffic and low-conversion-% test - obviously this wouldn't be an issue for regular tests yielding conversions daily. See below the graph shows no users in a variation that has no conversions for that day, causing a seemingly large discrepancy in the split between the variations. I believe this could be fixed with a left join from __overallUsers to __stats In total aggregate results the numbers seem to be ok so only a minor issue any case

Yeah, that's a good point. I'll take a look and see if changing the join type would work or if that will break some other things.
