title: How do I get a simple scatter plot of a dataframe (preferrably with seaborn)
body: <p>I'm trying to scatter plot the following dataframe:</p>
  
  <pre><code>mydf = pd.DataFrame({'x':[1,2,3,4,5,6,7,8,9], 
                   'y':[9,8,7,6,5,4,3,2,1], 
                   'z':np.random.randint(0,9, 9)},
                  index=["12:00", "1:00", "2:00", "3:00", "4:00", 
                         "5:00", "6:00", "7:00", "8:00"])
  
  
  
          x   y   z
   12:00  1   9   1
    1:00  2   8   1
    2:00  3   7   7
    3:00  4   6   7
    4:00  5   5   4
    5:00  6   4   2
    6:00  7   3   2
    7:00  8   2   8
    8:00  9   1   8
  </code></pre>
  
  <p>I would like to see the times "12:00, 1:00, ..." as the x-axis and <code>x,y,z</code> columns on the y-axis.</p>
  
  <p>When I try to plot with pandas via <code>mydf.plot(kind="scatter")</code>, I get the error <code>ValueError: scatter requires and x and y column</code>. Do I have to break down my dataframe into appropriate parameters? What I would really like to do is get this scatter plotted with seaborn.</p>
