title: multiple y axes (matplotlib) - unable to define scale increments
body: <p>Two follow-up questions to a post from yesterday (<a href="https://stackoverflow.com/questions/34006443/unable-to-control-scale-of-second-y-axis-on-df-plot">Multiple Y Axes</a>), is it possible to: </p>
  
  <ol>
  <li>Set the scale increments with ylim or yticks? (so that they line up at 5 steps each)</li>
  <li>Change the right Y-axis data to kind='bar' ?</li>
  </ol>
  
  <p>The gridlines do not match up (see image):</p>

  <p>Edit:  I did not understand that I was plotting in 2D lines by default, so I was trying to change the "kind" as I would in pandas; for example, df.plot(kind='').</p>
