Hello @cokello and welcome to the SAS Support Communities!
I have never used Visual Analytics, but from the documentation
If you select Normalize groups to 100%, then the values for each grouped bar are displayed as percentages of the total.
I conclude that you would divide the individual values (≥0) by the sum of all values (≥0) in the same group and multiply by 100% to obtain percentages (summing to 100% in each group).
In the example bar chart presented in the 2014 post Re: 100% Stacked Bar Charts:
If the revenues of the product lines A, B, C and D in facility region "South" are denoted by R A , R B , R C and R D , respectively, then the corresponding percentages p A , p B , etc. (depicted in the stacked bar chart as the heights of the blue, green, red and yellow section of the first bar) are calculated as
p A = 100% ∙ R A /(R A +R B +R C +R D )
p B = 100% ∙ R B /(R A +R B +R C +R D )
and so on
and similarly for the other three regions.
