mpl_toolkits.mplot3d.art3d.get_dir_vector(zdir)[source]¶ Return a direction vector.
Parameters: - zdir{'x', 'y', 'z', None, 3-tuple}
The direction. Possible values are:
- 'x': equivalent to (1, 0, 0)
- 'y': equivalent to (0, 1, 0)
- 'z': equivalent to (0, 0, 1)
- None: equivalent to (0, 0, 0)
- an iterable (x, y, z) is returned unchanged.
Returns: - x, y, zarray-like
The direction vector. This is either a numpy.array or zdir itself if zdir is already a length-3 iterable.
