body: <p>How to change the location the 'r' axis for matplotlib polar plot?</p>
  
  <p>I am trying to change the location of the r axis in a polar plot.
  At the moment it is being covered up by the data, but there is a gap in the data at theta = 340-360 degrees (in my real data example this is actually approx. 45 degrees) so it would be good if i could put axis labels there, in the data gap.</p>
  
  <pre><code>import random
  import numpy as np
  import matplotlib.pyplot as plt
  sampleSize=1000
  az=[]
  inc=[]
  for i in range(sampleSize):
      az.append(random.randint(0,340)) #not to the full 360 to represent my natural gap in the data
      inc.append(random.randint(0,90))
  
  plt.figure()
  plt.polar(np.radians(az),inc,'o')
  plt.show()
  </code></pre>
