title: How to change the linewidth of hatch in matplotlib?
body: <p>Is there a way to increase the width of hatch in matplotlib?</p>
  
  <p>For example, the following code by specifying <code>linewidth</code> only changes the width of the edge.  I want to change the linewidth of the line used for hatch.</p>
  
  <pre><code>import matplotlib.pyplot as plt
  import numpy as np
  
  x = np.random.randn(100)
  
  fig = plt.figure()
  ax = fig.add_subplot(111)
  ax.hist(x, fill=False, hatch='/', linewidth=2)
  
  plt.show()
  </code></pre>
