sorting stacked bar chart / one dimension multiple values

[sebastian_lueer]

What I am failing to accomplish is to change the sorting order of my one dimensional stacked bar chart

I always want 'Rechnungen' (dark green) at the bottom, then 'Aufträge' (light green) then 'Plan' (grey)

I created "master values" due to the request for specific colours, in the values I added an expression which is calculating sums for document types for the current month.

I tried different ways, last thing I tried was sorting in alphabetical order, hence the 'AA , AB ...' but dindt work at all 🙂

if someone could help me out, that would be awesome. I probebly setup the whole thing in a wired way but i am just transitioning over from excel and this is all very new to me 😉

Thank you !
