Represent value in Milions in a Bar Chart + Represent % from a different value (not from the total)

Hello,

 

My client needs to see in a chart the values in Millions and in the same time the % of that value, but not from the total of the other values in Millions; he wants to see the % of the value from another different value that is in another (single) column.

 

I was trying several options with other kinds of visuals (like the lineStackedColumnComboChart) but it doesn't work.

 

Anyone knows please a way to do it?
