The reason for this fudge in contour is that contourf fills lower < z <= upper for each consecutive pair of contour levels. When the minimum value of z coincides with the lowest level, then regions with that minimum are left blank; so the lowest level is adjusted downward slightly, making the lowest contour interval include the minimum value. The fudge could be made optional via a kwarg, e.g., include_minimum=True (default) or False (to defeat the fudge). This would not help Mario, though, assuming he is happy with the present contouring, and simply wants sane labeling of the 0-tick. For that, a Formatter adjustment is the simplest solution.
