title: Colorbar too big - Python Matplotlib
body: <p>I want to plot a geodataframe from Buenos Aires, the proportion of poor houses. There's the code:</p>
  
  <pre><code>import pandas as pd
  import geopandas as gpd
  import matplotlib.pyplot as plt
  caba=gpd.read_file('https://bitsandbricks.github.io/data/CABA_rc.geojson')
  </code></pre>
  
  <p>The problem: the colorbar it's too big. I tried to pass some "legend_kwds" but there is an error.</p>
  
  <pre><code>fig, ax = plt.subplots(figsize=(10,10))
  ax.set_aspect('equal')
  
  
  caba.plot(ax=ax, column='HOGARES_NBI', cmap='viridis',edgecolor='grey',linewidth=0.01,
            facecolor='r', legend=True, legend_kwds={})
  
  plt.title('Proporción de hogares \n con al menos una necesidad básica insatisfecha',fontsize=15)
  ax.set_axis_off()
  </code></pre>
  
  <p><a href="https://i.stack.imgur.com/cszdk.png" rel="nofollow noreferrer">Here's the image of the really BIG colorbar</a></p>
  
  <p>I tried to pass {'prop':{'size':2}} but it don't work.</p>
  
  <p>The error: <code>__init__() got an unexpected keyword argument 'prop'</code></p>
  
  <p>Thanks!</p>
