title: Plot smooth line with PyPlot
body: <p>I've got the following simple script that plots a graph:</p>
  
  <pre><code>import matplotlib.pyplot as plt
  import numpy as np
  
  T = np.array([6, 7, 8, 9, 10, 11, 12])
  power = np.array([1.53E+03, 5.92E+02, 2.04E+02, 7.24E+01, 2.72E+01, 1.10E+01, 4.70E+00])
  
  plt.plot(T,power)
  plt.show()
  </code></pre>
  
  <p>As it is now, the line goes straight from point to point which looks ok, but could be better in my opinion. What I want is to smooth the line between the points. In Gnuplot I would have plotted with <code>smooth cplines</code>.</p>
  
  <p>Is there an easy way to do this in PyPlot? I've found some tutorials, but they all seem rather complex.</p>
