Custom Visual - total percentage calculation

[sbeerh]

Hi,

I am developping a custom visual to make a specific chart that shows percentages accross 2 dimensions and the totals, like the table below.

           a           b           c        Total

x         2.3%     5.1%    7.1%     4.0%

y        8.2%     2.0%     4.3%     5.0%

Total  5.4%     4.0%     5.2%     4.7%

To be able to calculate the totals, I don't use the percentage measure that is available in the data model, but the numerator and the denominator.

I realize now that in the matrix visual I can add a percentage measure and the totals of the matrix are calculated correctly. 

Is there a way to have the same behavior in a custom visual? I don't understand how I could sum a percentage directely, but I'm probably missing a power BI concept.
