How to use two Y axes in Chart.js v2?
<p>I am trying to create a line chart with two datasets, each with its own Y scale / axis (one to the left, one to the right of the graph) using Chart.js.</p>

<p>This is my code (<a href="https://jsfiddle.net/zqx627kt/" rel="noreferrer">jsfiddle</a>):</p>

<pre><code>var canvas = document.getElementById('chart');
new Chart(canvas, {
  type: 'line',
  data: {
    labels: [ '1', '2', '3', '4', '5' ],
    datasets: [
      {
        label: 'A',
        yAxesGroup: 'A',
        data: [ 100, 96, 84, 76, 69 ]
      },
      {
        label: 'B',
        yAxesGroup: 'B',
        data: [ 1, 1, 1, 1, 0 ]
      }
    ]
  },
  options: {
    yAxes: [
      {
        name: 'A',
        type: 'linear',
        position: 'left',
        scalePositionLeft: true
      },
      {
        name: 'B',
        type: 'linear',
        position: 'right',
        scalePositionLeft: false,
        min: 0,
        max: 1
      }
    ]
  }
});
</code></pre>

<p>However, the second axis is not visible and the second dataset is still scaled exactly as the first (0 to 100 instead of 0 to 1). What do I need to change?</p>
