How to create a multi line chart with with dynamic x and y axis in one graph using chart js?

$(document).ready(function() {
  var traverse1 = [10,20,30,45,65,98];
  var traverse2 = [10,36,56,44,60,100];
  var traverse3 = [55,65,90,49,55,13];
  var traverse4 = [59,68,95,59,35,15];
  var master = [0.1,0.2,0.3,0.5,,0.6];

  chartCall(master, traverse1, traverse2, traverse3, traverse4);

  document.getElementById('update').addEventListener('click', function () {
    var traverse1 = getRandomValues(6);
    var traverse2 = getRandomValues(6);
    var traverse3 = getRandomValues(6);
    var traverse4 = getRandomValues(6);
    var master = [0.1,0.2,0.3,0.5,,0.6];
    chartCall(master, traverse1, traverse2, traverse3, traverse4);
  });

  function chartCall(master, traverse1, traverse2, traverse3, traverse4) {
    var canvas = document.getElementById("barChart");
    var ctx = canvas.getContext('2d');

    // Global Options:
    Chart.defaults.global.defaultFontColor = 'black';
    Chart.defaults.global.defaultFontSize = 16;

    var dataFirst = {
      label: "Traverse 1",
      data: traverse1,
      borderColor: "rgb(151,187,205)",
    };

    var dataSecond = {
      label: "Traverse 2",
      data: traverse2,
      borderColor: "rgb(220,220,220)",
    };

    var dataThird = {
      label: "Traverse 3",
      data: traverse3,
      borderColor: "rgb(247,70,74)",
    };

    var dataFourth = {
      label: "Traverse 4",
      data: traverse4,
      borderColor: "rgb(70,191,189)",
    };

    var speedData = {
      labels: master,
      datasets: [dataFirst,dataSecond,dataThird,dataFourth]
    };

    // Chart declaration:
    var myBarChart = new Chart(ctx, {
      type: 'line',
      data: speedData,
      options: {}
    });
  }

  function getRandomValues(length) {
    var values = [];
    for (var i = 0; i < length; i++) {
      values.push(Math.random() * 10);
    }
    return values;
  }
});
