I want to display data from 5 years back to the current year. Therefore, I do not want the expression to be fixed in the sense that it shows 2012-2017 because next year I want it to show 2013-2018. Is there a variable I could create (I already have a variable vCurrentYear) or an expression I could use to show a range of dates?
Right now, this is the portion of the expression and it only shows the data point for 2017 because of vCurrentYear:
The blue equal sign in the $-sign expansion forces the content to be treated as an expression. If your variable vCurrentYear is correctly set, the calculation will result in a value indicating four years ago.
