I am trying to emulate the Set Analysis Example in the Sample QVD Executive Dashboard of the line chart where it displays the complete trend over a time period and then highlights a particular time section based on an alternate state. The background color expression in the example is:
if([Book MonthYear]=[Book MonthYear],LightBlue(),LightGray())
I want the [Book Month Year] in Alternate state A = [Book Month Year] in alternate state B, then LightBlue(),LightGray()
I'm having problems getting the syntax correct.
