title: Chartjs scaleLabel position
body: <p>Trying to get the Y axis scale labels to look like the <a href="https://i.stack.imgur.com/XgoxX.png" rel="noreferrer">image</a>, to be position on top of the scale and not rotated.</p>
  
  <p>scale options currently look like:</p>
  
  <pre><code>    scales: {
    yAxes: [{
      id: 'temp',
      scaleLabel: {
        display: true,
        labelString: '°C'
      },
      type: 'linear',
      position: 'left'
    }, {
      id: 'ppm',
      scaleLabel: {
        display: true,
        labelString: 'ppm',
      },
      type: 'linear',
      position: 'left',
      ticks: {
        stepSize: 500
      }
    }, {
      id: '%',
      scaleLabel: {
        display: true,
        labelString: '%',
      },
      type: 'linear',
      position: 'right',
      ticks: {
        max: 100,
        min: 0
      }
    }]
  }
  </code></pre>
