At the very least the SetLimits() docs should explicitly state that this function does _not_ do what 90% of users expect it to do (which is to determine the range of the axis shown when drawn) [1]. Especially as it appears in the docs before the more obscurely named functions SetRange() and SetRangeUser().

[1] What does it even mean to limit the range of an axis if not for plotting purposes? Particularly for a TGraph which you pass all the points it will ever know about when you first create it.
