I could probably allow the user to tell plot where they are, but I can't think of a good API for it. I'd want something general enough to handle 1D, 2D and 3D functions, which allows the user to specify countably many missing values, and direction of (dis)continuity.


Isn't this where a well-specified exception interface could help? It won't be fast but at least you can specify singularities as exceptions.
