I wanted to check if it's possible to have a line chart with mixed granualrity - for instance:
a) average country level vs average regional level vs 2-3 selected city levels
(i know I could create calculated columns - but if I have multiple cities - it's too many) - Ideally, I would like to select items on slider/selector. However, what happens by default is that they values just add up (for instance, if I select 3 cities, I get their combined average instead of 3 separate lines) - also currently default line view does not seem to allow mixing hierarchy levels.
The hierarchy is built already - under Dim Group - but I don't see a way to display multiple levels under Legend. It only allows input of 1 category. Ideally, I'd like to compare sales of CA to 1 location such as NYC or compare Region sales to a location sale. Please let me know if you need further clarifications. Attachment is here: Sample pbix
