Hi, In the attached file I only changed one chart to save time but I think it shows you exactly how to achieve what you need.
First you need to create an alternate state by going to you document settings and name the alternate state such as Alt1 for this example.
Then in you list box for YTD change the alternate state to Alt1.
In your chart expressions add to the set analysis YTD_Flag =[Alt1]::YTD_Flag for every function.
YTD Target Prob.qvw 204.5 K
I checked the attached application, If i have understood your issue then here is the solutions for it
you can go to Chart Object Properties>Presentation> uncheck Supress Zero Values and uncheck Supress Missing
And Chart Object Properties>Dimension>Check Show All values
And if you want you can supress null values from your dimension if you want(I noticed there is null value in the Country dimension)
