Do all your docs have either success or failure? If so, then the visual builder screen I showed should work because it's doing `transactionStatus:success/*`  
In this case `*` means all docs, which is both success and failure.

If some of your docs don't have either success or failure, then we'll need to use something other than `*` for the denominator.
