Attached you can see the issue I faced.
I'm using the below background color expression that cause the problem:
if( GetPossibleCount([Codice azienda]) = 1,
Column(1)) = 1, LightGreen(),
Column(1)) = 1, LightRed()
as result I get the LightRed color as dimension color in the legend that's wrong because I'd expected to see the first color on Colors->Data Appearance section that in this case is LightBlue.
How can I achieve it ?
Thanks in advance.
