var lineChartData = {
    labels: ["Data 1", "Data 2", "Data 3", "Data 4", "Data 5", "Data 6", "Data 7"], //тут
    datasets: [{
        fillColor: "rgba(220,220,220,0)",
        strokeColor: "rgba(220,180,0,1)",
        pointColor: "rgba(220,180,0,1)",
        data: [20, 30, 80, 20, 40, 10, 60] //тут
    }, {
        fillColor: "rgba(151,187,205,0)",
        strokeColor: "rgba(151,187,205,1)",
        pointColor: "rgba(151,187,205,1)",
        data: [60, 10, 40, 30, 80, 30, 20] //и тут
