I'm working with HighCharts and trying to update the chart series. So far, everything works fine when I use;

chart.series[0].setData([Date.UTC(2022, 9, 29,14,54,52), 34.74],[Date.UTC(2022, 9, 29,15,24,52), 35.6]);

However, the real data comes as a string such as;

data = '[Date.UTC(2022, 9, 29,14,54,52), 34.74]^[Date.UTC(2022, 9, 29,15,24,52), 35.6]';

Since the setData() method requires an Array of DateTime x and y values, I have to convert the above string to an array, which might be simple but I can't really get it working... I tried two ways:

1. using Array.from()

   v2 = '[Date.UTC(2022, 9, 29,14,54,52), 34.74]^[Date.UTC(2022, 9, 29,15,24,52), 35.6]'; line = v2.split('^'); data = Array.from(line);

2. using push()

   v2 = '[Date.UTC(2022, 9, 29,14,54,52), 34.74]^[Date.UTC(2022, 9, 29,15,24,52), 35.6]'; line = v2.split('^'); data = [] data.push(line)

but neither ways worked for me...

Can please someone point me to the right way of getting the array from the string?

Thanks Gus

the line array is fine. You should define line first by using var/let/const.

const v2 = '[Date.UTC(2022, 9, 29,14,54,52), 34.74]^[Date.UTC(2022, 9, 29,15,24,52), 35.6]';

const  line = v2.split('^');

Try this code:

 var result = "";
  var arrayOfDate = [];
  var data = '[Date.UTC(2022, 9, 29,14,54,52), 34.74]^[Date.UTC(2022, 9, 29,15,24,52), 35.6]';

 var array = data.split('^');

for (let i = 0; i < array.length; i  ) {
 var arr = array[i].replace('[Date.UTC(','').replace(']','').replace(')','');

 var miniArray = arr.split(',');

 var dt = Date.UTC(miniArray[0], miniArray[1],miniArray[2],miniArray[3],miniArray[4],miniArray[5]);


  arrayOfDate.push(dt);
  arrayOfDate.push(miniArray[6]);
}

chart.series[0].setData([arrayOfDate[0], arrayOfDate[1]],[arrayOfDate[2], arrayOfDate[3]]);
