Need help on making visuals in Power Bi

Hi, I have a measure where it is putting each customers units they bought for each year into buckets like 1-10,11-20,etc. I want to make a graph showing this visual. I have it in a matrix table and it works correctly. I want to put it into a graph where it counts up how many customers units for that year goes into the bucket. For example, customer A bought 4 units in 2015 then they would be counted as 1 in the 1-10 bucket. I have a measure for the buckets but am not sure how to make the graph where the buckets is the x-axis and the count of customers in each bucket is the y. Please help!
