Hello everyone, I'm trying to create a way to have the selection "standard deviation", today I need to insert a fixed number in the "Maximum distribution" formula, which in this case is 9 for the production profile. But I wanted to have a mute to create a way to select from 0 to 9 that standard deviation and the curve graph adjust the scale according to the standard deviation that I select.
Can anybody help me?
