The previous constructor of .axis3d.Axis, with signature
(self, adir, v_intervalx, d_intervalx, axes, *args, rotate_label=None, **kwargs)
is deprecated in favor of a new signature closer to the one of 2D Axis; it
is now (self, axes, *, rotate_label=None, **kwargs) where kwargs are
forwarded to the 2D Axis constructor. The axis direction is now inferred from
the axis class' axis_name attribute (as in the 2D case); the adir
attribute is deprecated.
The init3d method of 3D Axis is also deprecated; all the relevant
initialization is done as part of the constructor.
The d_interval and v_interval attributes of 3D Axis are deprecated; use
get_data_interval and get_view_interval instead.
