title: Chart.js How to get min-max values of X axis?
body: <p>How can I get the values ​​at both ends of the X axis?</p>
  
  <p>I use chartjs-plugin-zoom to zoom and pan time-series data charts. I want to get the minimum and maximum values of x-axis  ​​at that time.</p>
  
  <pre><code>zoom: {
      zoom: {
        enabled: true,
        mode: 'x',
        onZoom: function () {
           var min = myChart[i].getDatasetMeta(i).dataset._scale.chart.scales.x-axis-0.table[0].time;
           console.log('min', min);
        }
     }
  }
  </code></pre>
  
  <p>I expected to get the value from this.
  But "x-axis-0" contains an operator.</p>
  
  <p>What should I do?</p>
