formula in Bar graph not coming
I am not able to show formula in graph as it is not coming in the Available Field List of chart expert.
My req is like, I have the No of TTs and the TTR value for each TT.
According to my req. I have created 2 running total fields Sum of TTRs and Count of TTs.
In graph I have to show the Sum of TTRs / No of TTs. For this I have created the formula. My values are coming fine in report. But this formula I am not getting in chart.
Pls let me know why this is not coming in chart expert.
