Hi, perhaps I am misinterpreting the docs. When I run the following code, I expect the bottom-right arrow (element [2,0]) to point to the left. However, it’s the top-left as (see figure). Quiver seems to be transposing the U,V matrices. Am I missing anything?

```
import numpy as np
import matplotlib.pyplot as plt
x = np.linspace(0.3,.9,3)
y = x
nb_points = x.size
X,Y = np.meshgrid(x,y)
U = np.ones((nb_points, nb_points))
V = np.ones((nb_points, nb_points))
U[2,0] = -3
M = (np.hypot(U, V))
fig,ax = plt.subplots(1,1, figsize=(4,4))
ax.quiver(X, Y, U, V, M, units='width', pivot='middle')
ax.set_xlim(.2,1)
ax.set_ylim(.2,1)
```
