I'm not sure I understand this fully but I'll make some assumptions
First you want 35% Sales from the first half of the year and 55% of sales from the second half .
you want a single measure that does this so you can have a bar chart
The key to what I am demonstrating in this sample is using the search capability in Set Analysis, when you use double quotes "" in your set modifier qlik will search with wildcard characters or inequality comparisons like >=
Single quotes ''would give you an exact value match.
//Range sum is a non aggregate function that adds to calculations together
RangeSum(
//This is the First Half of the year
Sum({<Week ={">=1<=26"}>}Sales) * .35
,
//This is the Second Half of the year
Sum({<Week ={">=27<=52"}>}Sales) * .55
)
If this does not help try to explain your case with a little more detail and we'll see if we can figure it out.
