Matplotpb - Quiver Plot

A quiver plot displays the velocity vectors as arrows with components (u,v) at the points (x,y).

quiver(x,y,u,v)

The above command plots vectors as arrows at the coordinates specified in each corresponding pair of elements in x and y.

Parameters

The following table psts down the different parameters for the Quiver plot −

The following code draws a simple quiver plot −

import matplotpb.pyplot as plt
import numpy as np
x,y = np.meshgrid(np.arange(-2, 2, .2), np.arange(-2, 2, .25))
z = x*np.exp(-x**2 - y**2)
v, u = np.gradient(z, .2, .2)
fig, ax = plt.subplots()
q = ax.quiver(x,y,u,v)
plt.show()
