Webi - need to create graph on Total values

Hi,

I need to create graph for few unique measure at the end of the table which are created by using formula. I cant select rows name which i have typed in the table. creating a variable is not option as i have 4 sums for 3 measures on three reports, for which i need to create 36 variables. I see folder called formula, when i turn table to column graph but its empty, is there any way i can use this folder.

Thanks.
