title: Plotting quantiles, median and spread using scipy and matplotlib
body: <p>I am new to matplotlib, and I want to create a plot, with the following information:</p>
  
  <ol>
  <li>A line joining the medians of around 200 variable length vectors (input)</li>
  <li>A line joining the corresponding quantiles of these vectors.</li>
  <li>A line joining the corresponding spread (largest and smallest points).</li>
  </ol>
  
  <p>So basically, its somewhat like a continuous box plot.</p>
  
  <p>Thanks!</p>
