I have to make a different calculation on a conventional line and totals. I found a solution, given the forum, using the formula: STR (ATTR ([my value])) <> '*'.
The problem is that I have special cases where I have a single line in my group. In this case, Tableau does not detect the total line.
The total should be green.
An idea ?
That's a drawback of the ATTR() solution. The only thing that I know of that works in this case is to use a separate method for customizing totals, namely Custom SQL to duplicate your data. See http://drawingwithnumbers.artisart.org/customizing-grand-totals-part-3/ for details on how to do this.
