how to join several arrays in one-CodePudding

I have this array

[{"temp":"24.44","time":"2021-11-26 22:23:29.370657"},
 {"temp":"25.44","time":"2021-11-26 22:23:35.411530"}]

and i need this

data.addRows([
    [24.44, [22, 23, 29]], 
    [25.44, [22, 23, 35]]
  ]);

It is to be able to make a graph, thanks for your help.

1) You can make use of

const arr = [
  { temp: "24.44", time: "2021-11-26 22:23:29.370657" },
  { temp: "25.44", time: "2021-11-26 22:23:35.411530" },
];

const result = arr.map(({ temp, time }) => {
  const [a, b, c] = time.match(/[^\s] ([^\.] )/)[1].split(":");
  return [ temp, [ a,  b,  c]];
});

console.log(result);

  google.charts.load('current', {'packages':['line', 'corechart']});
  google.charts.setOnLoadCallback(drawChart);

function drawChart() {

  
  var chartDiv = document.getElementById('chart_div');

  var data = new google.visualization.DataTable();
  data.addColumn('timeofday', 'Fecha');
  data.addColumn('number', "Average Temperature");
  
  

  var materialOptions = {
    chart: {
      title: 'Average Temperatures and Daylight in Iceland Throughout the Year'
    },
    width: 900,
    height: 500,
    series: {
      // Gives each series an axis name that matches the Y-axis below.
      
     
    },
    axes: {
      // Adds labels to each axis; they don't have to match the axis names.
      y: {
        Temps: {label: 'Temps (Celsius)'},
        
      }
    }
  };

  

  var materialChart = new google.charts.Line(chartDiv);
   

   setInterval(function() {
                var JSON = $.ajax({url:"http://localhost/maintpro/datos_sensor.php?q=1",dataType: 'json',async: false}).responseText;
                const respuesta = jQuery.parseJSON(JSON);

                const result = respuesta.map((o) => [
                    o.time.split(" ")[1].split(".")[0].split(":").map(Number),
                     o.temp,
                ]);

            
                data.addRows(result);
                materialChart.draw(data, materialOptions);
            }, 1300);

}

It is working but that happens, help me please
