You will need to target the specific dataset you want to get the data from so to get the data of the Temperature - 1 dataset you will need to target it like this: myChart.data.datasets[0].data

Example:

var options = {
  type: 'line',
  data: {
    labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
    datasets: [{
        label: '# of Votes',
        data: [12, 19, 3, 5, 2, 3],
        borderColor: 'orange'
      },
      {
        label: '# of Points',
        data: [7, 11, 5, 8, 3, 7],
        borderColor: 'pink'
      }
    ]
  },
  options: {}
}

var ctx = document.getElementById('chartJSContainer').getContext('2d');
const myChart = new Chart(ctx, options);

console.log(myChart.data.datasets[0].label)
console.log(myChart.data.datasets[0].data)
