In particular i created a new function to fit my scatter data point and it works. Is it possible to change the costant value from the workbook? Because that costants change often and i'd like to automatize the process. I tried to put in the costant value the column name that i would like to change but unfortunately it ask me to fill only numbers. Thanks all Appreciate it Alessandro Piccolo [/quote]   Check here to include your profile signature. Check here to subscribe to this topic.
