Problem with adding data(variables)

[Mario D]

HELLO im drawing a google line chart and it is working with only one variable/line with a name zadnjiBroj, i want to add 2 more variables into chart, 2 more lines named zadnjiBrojy and zadnjiBrojz that will work on the same graph. Can anyone help me to implement that 2 more lines?

There is a code:

google.charts.load('current', {'packages':['corechart']});
var numbersFromLabView = [];
var time = [];



$('.viewbutton').click(function() {
  // Zovi api poziv i dohvati podatke svako 2 sec
  $('#portfolio').addClass('hidden');
  $('#element-di-zivi-aplikacija').removeClass('hidden');
  setInterval(getDataFromLabView, 2000);
});


function getDataFromLabView() {
  var jsonData = $.ajax({
    url: 'projectXHTTP',
    dataType: 'json',
    success: function (jsonArray) {
     
      var zadnjiBroj = jsonArray.slice(0,1).pop();
      var zadnjiBrojy = jsonArray.slice(0,2).pop();
      var zadnjiBrojz = jsonArray.slice(0,3).pop();
   
      drawChart(zadnjiBroj);
   
   
      $(document.querySelector('.current-number')).text(zadnjiBroj);
      $(document.querySelector('.current-numbery')).text(zadnjiBrojy);
      $(document.querySelector('.current-numberz')).text(zadnjiBrojz);
 
    }
  });
}


function drawChart(number) {
  var data = new google.visualization.DataTable();
 
  moment.locale('hr');
  time.push(moment());
  numbersFromLabView.push(number);


  // kako ce se zvati x i y osi na grafu
  data.addColumn('string', 'Time of Day');
  data.addColumn('number', 'Current');
 


  numbersFromLabView.forEach((number, key) =>  {
    // za svaki broj koji dohvati ubaci njega i vrijeme u data Objekt
    data.addRow([time[key].format('LTS'), number]);
  });


  // stilovi i izgled grafa se ovdje definiraju
  var options = {
    background: 'transparent',
    title: 'Numeric values from LabView on time scale',
    height: 500,
    width: '100%',
    hAxis: {
      title: 'Vrijeme',
    },
    vAxis: {
      title: 'I',
     
    }
  }


 
  var chart = new google.visualization.LineChart(document.querySelector('#chart_div'));
 
 
  chart.draw(data, options);
}
