title: nvd3's x-axis broken due to one line change?
body: <p>In this live code link,</p>
  
  <p><a href="http://nvd3.org/livecode/index.html#codemirrorNav" rel="nofollow">http://nvd3.org/livecode/index.html#codemirrorNav</a></p>
  
  <p>if you add <code>chart.yRange([0, 300])</code> for inverting the y-axis, the x-axis moves up
  and sticks to the top(near the legend).</p>
  
  <p>Any possible fix?</p>
  
  <p>PS: The problem is with most of the charts on that page but 'Cumulative line chart' is closest to my use case.</p>
