title: How to make two plots side-by-side
body: <p>I found the following example on matplotlib:</p>
  
  <pre><code>import numpy as np
  import matplotlib.pyplot as plt
  
  
  x1 = np.linspace(0.0, 5.0)
  x2 = np.linspace(0.0, 2.0)
  
  y1 = np.cos(2 * np.pi * x1) * np.exp(-x1)
  y2 = np.cos(2 * np.pi * x2)
  
  plt.subplot(2, 1, 1)
  plt.plot(x1, y1, 'ko-')
  plt.title('A tale of 2 subplots')
  plt.ylabel('Damped oscillation')
  
  
  plt.subplot(2, 1, 2)
  plt.plot(x2, y2, 'r.-')
  plt.xlabel('time (s)')
  plt.ylabel('Undamped')
  
  plt.show()
  </code></pre>
  
  <p>My question is: What do i need to change, to have the plots side-by-side?</p>
