Poderia me ajudar como eu pego os dados dessa arquivo js, e passo eles para o gráfico?

Arquivo Sensordata.js (obter dados do arduino)

function startButtonHolder(){
  return 0;
}

async function getSensorsDatas(){

  // Making communication with Serial Port
  var SerialPort = require('serialport');
  var Readline = SerialPort.parsers.Readline
  // '/dev/ttyACM0' is the port for arduino
  var path = '/tmp/ttyV0' // '/tmp/ttyV0' for data simulation
  var port = new SerialPort(path, {
    // Same rate as arduino
    baudRate: 9600,
  });

  // If it starts communication desactivate button
  port.on('open', function(err) {
    document.getElementById('start-sensors-button').setAttribute( "onclick", "startButtonHolder()" );
  });

  // Sleep 200ms to get real result of port.isOpen
  await sleep(200);

  // Give alert if fail to connect
  if(!port.isOpen){
    const {dialog} = require('electron').remote
    const dialogOptions = {title: 'Erro de comunicação', type: 'info', buttons: ['OK'], message: 'Não foi possível realizar a conexão com o sensor.\nVerifique se o mesmo está conectado e tente novamente.'}
    dialog.showMessageBox(dialogOptions)
  }

  port.on('close', function (err) {

    document.getElementById('start-sensors-button').setAttribute( "onclick", "getSensorsDatas()" );

    dialog.showMessageBox(dialogOptions)
  });

  // Adding parse so it gets full line instead of parts
  var parser = new Readline()
  port.pipe(parser)

  // Aux variable to know if last data was serial number or temperature
  var lastData;

  // Getting data from serial port
  parser.on('data', function (data) {
    var parsed_data = parseFloat(data);

Grafico:

google.charts.setOnLoadCallback(drawChart);
