Chart.js axes label font size : <p>In chart.js how can I set the set the font size for just the x axis labels without touching global config?</p>

<p>I've already tried setting the 'scaleFontSize' option my options object.
I've also tried setting:</p>

<pre><code>{
  ...
  scales: {
    xAxes: [{
      scaleFontSize: 40
      ...
    }]
   }
}
</code></pre>
