Microsoft Power BI has a cool feature in Preview, that allows you to split a single visual into multiple visuals based on a filter.  In this video, I take Sales by Customer Class (Group/Category), create small multiples based on the class, and make the axis a class for Items sold. This feature works on several of the “out of the box” visuals.  In the attached video, I will use a clustered column chart and a line and clustered column chart.

I love using this feature when the visual (using the small multiples) is the only visual on the page, taking the entire page. 

I will also show you some formatting options for small multiples as well.

Super cool feature Microsoft!
