title: Superposing Pandas time series from different years in Seaborn plot
body: <p>I have a Pandas data frame, and I want to explore the periodicity, trend, etc of the time series. <a href="https://drive.google.com/file/d/0B2u3MNOqrn8cYUtXblVRb21CNXc/view" rel="nofollow noreferrer">Here</a> is the data.</p>
  
  <p>To visualize it, I want to superpose the "sub time series" for each year on the same plot (ie have the same x coordinate for data from 01/01/2000, 01/01/2001 and 01/01/2002).</p>
  
  <p>Do I have to transform my date column so that each data has the same year?</p>
  
  <p>Does anyone have an idea of how to do that?</p>
