title: how to target all vectors on the map without losing scale?
body: <p>I'm trying to direct the arrows across the map to indicate the wind direction, but it just stays at the edges of the map... How to adjust it to the whole map?</p>
  <pre><code>import matplotlib.pyplot as plt
  import matplotlib.colors as mcolors
  import matplotlib.cm as cm
  import numpy as np
  
  lon= (af.x)
  lat= (af.y)
  m= df1['Vvento_ms_AVG']
  u= df1['Dvento_D1_WVT']
  v= (df1['Dvento_SD1_WVT'])
  u_norm = u / np.sqrt(u ** 2.0 + v ** 2.0)
  v_norm = v / np.sqrt(u ** 2.0 + v ** 2.0)
  
  fig, ax = plt.subplots()
  q = ax.quiver(lon, lat, v_norm, u_norm, m, scale=20,  
         pivot = &quot;tail&quot;, alpha=1)
  cbar = plt.colorbar(q, ax=ax)
  cbar.set_label('Velocidade média em m/s')
  plt.title(&quot;Velocidade média em m/s e direção do vento em Piracicaba/SP em 31/12/2021&quot;)
  cidade_pira.boundary.plot(ax=ax, color='gray', zorder=2)
