Drill down

[princyal]

Hi,

I drill down the two dimension

1st is  =If([E5-1]='Yes',Dual('Y',1),if([E5-1]='No',Dual('N',2)))

2nd is Office

 The bar chart is there only one type of value in particular office hence its drill down in directly to the office

But , the user requirement is When we put a filter on office we get the  Yes and No only.

If its possible in qliksense we can so Yes or No 

Please help me out solve the problem 

Thanks,

princy
