You can do this with quiver, but it’s a little tricky to get the keyword arguments right.
import numpy as np
import matplotlib.pyplot as plt
x = np.linspace(0, 2*np.pi, 10)
y = np.sin(x)
plt.figure()
plt.quiver(x[:-1], y[:-1], x[1:]-x[:-1], y[1:]-y[:-1], scale_units="xy", angles="xy", scale=1)
plt.show()
