Binning is grouping a numeric field based on a division. This type of grouping is called Banding as well. For example you might have customers with different yearlyIncome range from $10,000 to $100,000 and you want to create a banding by $25,000. This will generate 4 groups of yearly income for you. This is exactly what Binning in Power BI does. Let’s look at the example.
Create a Table in Power BI Report and visualize YearlyIncome (from DimCustomer), and SalesAmount (from FactInternetSales) in it. Change the aggregation of YearlyIncome from Sum to Do Not Summarize as below
You could already build this yourself, but I’m glad they introduced this, as it’s an easier solution.
