In responding to an inquiry about an exception raised when using "plot(..., markerfacecolor=None)"
(http://www.mail-archive.com/[EMAIL PROTECTED]/msg07627.html) I made a small change to avoid the problem. My question is, should the following be raised to a general principle, to be followed with at most rare exceptions? Whenever there is a setter for an artist property, that setter should be used in the artist __init__method, with no additional logic, so that a kwarg setting in __init__ has the same effect as calling the artist update method with that kwarg. This affects plot in particular because the line property kwargs are not used via the __init__ method but are applied by calling update(). Typically there is some logic along the lines if kw is None: kw = defkw and I am suggesting that this handling of None as a default should always be moved to a setter if one exists. That way, a user can always get a property back to its default value by setting it to None. Does anyone immediately see any problem or disadvantage in this? (I have not looked through the code carefully myself, so I could easily be missing something.)
