Let’s use an example of a payments business. The question I’m trying to answer is how many different businesses did a user make a payment with in the last month?

I have an event = Payment Completed, which fires when a user makes a payment with a business

The event has a property = Business Name, which details the specific business that the user made the payment with.

I would like to see a histogram of the number of businesses users made at least 1 payment with, within a specific time period

eg. in the last month 
- the number of users who made at least 1 payment with 1 business only = X
- the number of users who made at least 1 payment with 2 businesses = Y
- the number of users who made at least 1 payment with 3 businesses = Z
etc.

I know Segment’s computed traits could do this, but I’m trying to work out how I can answer this question within Amplitude. Any help would be really appreciated.
