✅

Just stack the axes:

var options = {
  type: 'line',
  data: {
    labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange", "Black"],
    datasets: [{
        label: 'Dataset 1',
        data: [10, 30, 50, 20, 25, 44, -10],
        borderColor: 'red',
        backgroundColor: 'red'
      },
      {
        label: 'Dataset 2',
        data: [10000, 30000, 50000, 20000, 25000, 44000, -10000],
        borderColor: 'blue',
        backgroundColor: 'blue',
        yAxisID: 'y2',
      }
    ]
  },
  options: {
    scales: {
      y: {
        type: 'linear',
        position: 'left',
        stack: 'demo',
        grid: {
          borderColor: 'red'
        },
        title: {
          display: true,
          text: 'hello'
        }
      },
      y2: {
        offset: true,
        position: 'left',
        stack: 'demo',
        grid: {
          borderColor: 'blue'
        },
        title: {
          display: true,
          text: 'hello2'
        }
      }
    }
  }
}

var ctx = document.getElementById('chartJSContainer').getContext('2d');
new Chart(ctx, options);
<body>
  <canvas id="chartJSContainer" width="600" height="400"></canvas>
