body: <p>How to change the figure width and height when using cartoopy. figsize change only the white space around the figure, yet not the figure itself. Any ideas. </p>
  
  <pre><code>import cartopy.crs as ccrs 
  import cartopy.feature as cfeature
  import matplotlib.pyplot as plt
  
  def main():
      fig = plt.figure(figsize=(10,10))
      ax = fig.add_subplot(1, 1, 1, projection=ccrs.PlateCarree())
      ax.set_extent([-20, 60, -40, 45], crs=ccrs.PlateCarree())
  
      ax.add_feature(cfeature.LAND)
      ax.add_feature(cfeature.OCEAN)
      ax.add_feature(cfeature.COASTLINE)
      ax.add_feature(cfeature.BORDERS, linestyle=':')
      ax.add_feature(cfeature.LAKES, alpha=0.5)
      ax.add_feature(cfeature.RIVERS)
  
      plt.show()
  
  if __name__ == '__main__':
      main()
