If the variation is about 16% or more of the largest value, the minimum reverts to zero, and people with XY charts complain about all the white space. Perhaps what is needed is for Excel to use two different scaling methods, one for marker-related data, the other for bar-related data. I generally use my own aalgorithms, through worksheet formulas or through VBA, so I get what I want. Unfortunately this exceeds the capabilities of the great huddled masses.
