[Solved]-Can't generate multi-axis combo chart (bar/line) using chart.js 2.7-Chart.js

  var x_time  = ['00:00', '00:30', '01:00', '01:30', '02:00', '02:30'];
  var y_data1 = ['99.83', '99.86', '99.81', '99.83', '99.72', '99.75'];
  var y_data2 = ['56', '41', '53', '46', '70', '60'];
  new Chart(document.getElementById('myChart').getContext('2d'), {
    type: 'bar',  // <-- define overall chart type
    data: {
      labels: x_time,
      datasets: [{
        type:'line',
        label: 'Data1',
        fill:false,
        backgroundColor: 'rgb(255, 99, 132)',
        borderColor: 'rgb(255, 99, 132)',
        data: y_data1,
        yAxisID: 'left-axis'
      }, {
        label: 'Data2',
        fill: true,
        backgroundColor: 'rgb(54, 162, 235)',
        borderColor: 'rgb(54, 162, 235)',
        data: y_data2,
        yAxisID: 'right-axis'
      }]
    },
    options: {

      maintainAspectRatio:false,
      responsive: true,
      title: {display: false},
      tooltips: {mode: 'index', intersect: false},
      hover: {mode: 'nearest', intersect: true},
      scales: {
