Hello all,
I am trying to add a quiver plot to my dash app comparing the wind directions of different sources using the create_quiver function of the plotly.figure_factory package. The arrows I get have different lengths depending on the wind speed. However, my aim is t plot only the direction. I tried normalizing the wind components this way :

import plotly.figure_factory as ff
import numpy as np
![newplot (33)|690x168](upload://i8AYByBc8UrYBgdY1QXejq9bACe.png)
x,y = np.meshgrid(np.arange(0, 2, .2), np.arange(0, 2, .2))
u = np.cos(x)*y
v = np.sin(x)*y
N = np.sqrt(u**2 + v**2)
u /= N
v /= N
fig = ff.create_quiver(x, y, u, v,scaleratio=0.1, scale=0.5)
fig.show()
