title: Pandas Dataframe Multicolor Line plot
body: <p>I have a Pandas Dataframe with a DateTime index and two column representing Wind Speed and ambient Temperature. Here is the data for half a day</p>

  <p>I would like to plot this data as one line where the color changes according to temperature. So from light red to dark red the higher the temperature for example. </p>
  
  <p>I found this <a href="http://nbviewer.ipython.org/github/dpsanders/matplotlib-examples/blob/master/colorline.ipynb" rel="nofollow">example of multicolored</a> lines with matplotlib but I have no idea how to use this with a pandas DataFrame. Has anyone an idea what I could do? 
  If it is possible to do this, would it also be possible as additional feature to change the width of the line according to wind speed? So the faster the wind the wider the line.</p>
  
  <p>Thanks for any help!</p>
