axis : {'both', 'x', 'y'}, default: 'both' The axis on which to operate. (For 3D Axes, *axis* can also be set to 'z', and 'both' refers to all three axes.) tight : bool or None, default: None If True, first set the margins to zero. Then, this argument is forwarded to `~.axes.Axes.autoscale_view` (regardless of its value); see the description of its behavior there. NTŠ
