title: Change figsize in matplotlib
body: <p>It seems that the figsize option only changes the ratio of the height to width. Atleast this is the case when using jupyter notebooks. Here is an example:</p>
  
  <pre><code>import matplotlib.pyplot as plt
  %matplotlib inline
  import numpy as np
  
  plt.figure(figsize=(16,8))
  plt.plot(np.arange(1,10),np.arange(1,10))
  plt.show()
  plt.figure(figsize=(24,6))
  plt.plot(np.arange(1,10),np.arange(1,10))
  plt.show()
  </code></pre>
  
  <p>I was hoping that figsize intended inches, not a relative ratio. How would you go about enforcing that in python/ jupyter notebooks.</p>
