I'm trying to do a plot with quiver but I would like the arrows to all have the same size.
I use the following input :
q = ax0.quiver(x, y, dx, dy, units='xy' ,scale=1)
But even if add options like norm = 'true' or Normalize = 'true' the arrows are not normalized
Any one knows how to do this ? Thank you
Not sure if there is a way to do this by explicitly providing a kwarg to plt.quiver, but a quick work around would be like this:
x = np.arange(10)
y = np.arange(10)
xx, yy = np.meshgrid(x,y)
u = np.random.uniform(low=-1, high=1, size=(10,10))
v = np.random.uniform(low=-1, high=1, size=(10,10))
plt.quiver(xx, yy, u, v)
r = np.power(np.add(np.power(u,2), np.power(v,2)),0.5) #could do (u**2+v**2)**0.5, other ways...
plt.quiver(xx, yy, u/r, v/r)
this just normalizes the u and v components of the vector by the magnitude of the vector, thereby maintaining the proper direction, but scaling down the magnitude of each arrow to 1
