I have a column of data (all numbers) that I would like to generate a series from based on the max/min with a constant step value. For example, if I enter 100 #'s with a min of 1 and a max of 20 I would like excel to generate a series from 1:20 with a step of 1. Then if I decide to enter more data it would change according to the new min/max with a step of 1. Is this possible?
