skspatial.objects.Vector.plot_3d

Vector.plot_3d(ax_3d: Axes3D, point: Union[ndarray, Sequence] = (0, 0, 0), scalar: float = 1, **kwargs) → None

Plot a 3D vector.

The vector is plotted by connecting two 3D points (the head and tail of the vector).

Parameters:

ax_3dAxes3D

Instance of Axes3D.

pointarray_like, optional

Position of the vector tail (default is origin).

scalar{int, float}, optional

Value used to scale the vector (default 1).

kwargsdict, optional

Additional keywords passed to plot().

Examples

>>> import matplotlib.pyplot as plt
>>> from mpl_toolkits.mplot3d import Axes3D

>>> from skspatial.objects import Vector

>>> fig = plt.figure()
>>> ax = fig.add_subplot(111, projection='3d')

>>> Vector([-1, 1, 1]).plot_3d(ax, point=(1, 2, 3), c='r')
