title: Add x and y labels to a pandas plot
body: <p>Suppose I have the following code that plots something very simple using pandas:</p>
  
  <pre><code>import pandas as pd
  values = [[1, 2], [2, 5]]
  df2 = pd.DataFrame(values, columns=['Type A', 'Type B'], 
                     index=['Index 1', 'Index 2'])
  df2.plot(lw=2, colormap='jet', marker='.', markersize=10, 
           title='Video streaming dropout by category')
  </code></pre>
  
  <p><img src="https://i.stack.imgur.com/LIkH3.png" alt="Output"></p>
  
  <p>How do I easily set x and y-labels while preserving my ability to use specific colormaps? I noticed that the <code>plot()</code> wrapper for pandas DataFrames doesn't take any parameters specific for that.</p>
