Many thanks for your reply,
But this is not working..... As you mentioned i tried giving the same expression which is as below:
if(aggr(rank( Sum(if(Channel <>'Total' and (Product ='X' or Product='Y'),(Jan_Act+Feb_Act)))/1000000)<=10,Z)
Where Z= Drill down, so m not clear how to mention drill down in expression
After using this expression i am getting my first bar in both the charts same, but rest 9 bars are different.
Kindly provide me with the solution.
