Conditionally pick column as legend based on no. of items selected in slicer

[Anonymous]

Hi,

I want to choose a column as a legend based on number of items selected on filter. If I select greater than one item in a OPERATOR slicer, I want operator as a legend else if i select only one item  i want route name as a legend. Is this possible in power bi map ?

@amitchandak is there a way where i can just count the number of items in the slicer 'OPERATOR' and change legends based on the number of items selected ?
i dont want another slicer separately .. i want this work dynamically by counting the number of items selected in 'OPERATOR' slicer ...
