How to plot vectors in Python using Matplotlib?
To plot vectors in Python using matplotlib, we can take the following steps −
Create a matrix of 2×3 dimension.
Create an origin point, from where vecors could be originated.
Plot a 3D fields of arrows using quiver() method with origin, data, colors and scale=15.
Example
import numpy as np from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True data = np.array([[2, 1], [-1, 2], [4, -1]]) origin = np.array([[0, 0, 0], [0, 0, 0]]) plt.quiver(*origin, data[:, 0], data[:, 1], color=['black', 'red', 'green'], scale=15) plt.show()
