title: About the image size that generated from matplotlib
body: <p>I generated a histogram by using matplotlib</p>
  
  <pre><code>import numpy as np
  import pylab as P
  
  
  mu, sigma = 200, 25
  x = mu + sigma*P.randn(10000)
  
  
  P.figure()
  bins = 10
  n, bins, patches = P.hist(x, bins, normed=1, histtype='bar', rwidth=0.8)
  P.show()
  </code></pre>
  
  <p>I want to make the picture smaller, how could I do that?</p>
  
  <p>Thanks for your help</p>
