Show X axis on top and bottom in line chart rendered with Chart.js 2.4.0
<p>I have a line chart rendered with Chart.js and I display the X axis at the bottom:</p>

<pre><code>xAxes: [{  type: 'linear',
           position: 'bottom',
</code></pre>

<p>I would like to have two X axis, one at the bottom and one at the top.
I see in the documentation that <code>position</code> is a string, thus one value only.</p>

<p>Is it possible to accomplish this?</p>
