Why can't I show my data as Staked Area Graph?

Why can't I show my data as Staked Area Graph?

Hi all,

I need some help. I have a query table with 3 values. Lets call the values Red, Green and Yellow. I'd like to show these values as "Measure - Actual (Number)" values in the chart editor, I no longer have access to the stacked area charts, only line graphs.
