I've created a bar chart and tried to add a conditional palette based on an expression comparing two data items.
If Data1 < Data2 then make the bar red.
Data1 is the primary axis and Data2 is a colored region.
I've tried adding Data2 to the Property-Properties for the Primary Axis Member Node, however, I still get the OP-ERR-0131 Measure valueSet="Data1" can not have another measure as an attribute: groupBody="Data2"
Is there a solution?
