power BI Dynamic parameters

Hi All,

I am new to the Power BI. Need help on below issue.

My data is looks like :

vendor    Revenue  

abc          100          

xyz            200

edc          300

abc          200 

xyz          300

edc         500

My Slicer will be 1) All three vendors     2)     xyz vendor compare with abc+edc vendor

Note : In second option i am comparing xyz vendor with sum of remaing vendors.

Please help on below issue.
