How to use two Y axes in Chart.js v2?

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.

This is my code (jsfiddle):

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
      }
    ]
  }
});

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?

For ChartJs 2.x only a couple changes need to be made (it looks like you have tried to combine 2.x options with the multi-axes options from my fork?),

• The yAxes field needs to be in a scales object
• the yAxis is referenced by id not name.
• For the scale steps/size you just need to wrap these options in a ticks object.
• No need forscalePositionLeft this is covered by position

Example:

var canvas = document.getElementById('chart');
new Chart(canvas, {
  type: 'line',
  data: {
    labels: ['1', '2', '3', '4', '5'],
    datasets: [{
      label: 'A',
      yAxisID: 'A',
      data: [100, 96, 84, 76, 69]
    }, {
      label: 'B',
      yAxisID: 'B',
      data: [1, 1, 1, 1, 0]
    }]
  },
  options: {
    scales: {
      yAxes: [{
        id: 'A',
        type: 'linear',
        position: 'left',
      }, {
        id: 'B',
        type: 'linear',
        position: 'right',
        ticks: {
          max: 1,
          min: 0
        }
      }]
    }
  }
});
