How to sort inner stack bar in a chart

[Husky_Bab12]

I need to sort inner stack bar. I already have a expression used to maintain the order of the legend.

It may be implementation dependent. 

In general:

• If the bar graph "colour stripes" (technical term 🙂 ) come from a Dimension, then the same Sort Expression controls both the legend order and the stripe order. 
• If the bar graph colour stripes are the result of multiple Expressions, then the order of the Expressions (Promote/Demote) is what controls the order of the stripes.

Yes/no/maybe?
