chartist to display nice pie...

I need help.
Not so good with Javascript...  


I have this code:

Code:

function getdate(offset) {
  var date = new Date();

  date.setDate(date.getDate() + offset+1);

  var year = date.getFullYear();
  var month = date.getMonth() + 1;
  var day = date.getDate();

  return { year, month, day };
}






function getdata(nom, dayBefore, dayBase,total) {
    var result = [];
  var trendsName = [];
  var trendsAddress = [];
    var myJsonString='';

  //FIND GA NAME AND ADDRESS
  $.each(grp.tag(nom), function(id, object) {
    trendsName.push(object.name);
    trendsAddress.push(Scada.encodeGroupAddress(object.address));
  });

  // CREATE ARGUMENT
  var data = JSON.stringify({
    trends: trendsAddress,
    dates: {
      start: getdate(dayBefore),
      end: getdate(dayBase),
    },
    // resolution: 86400,
    // timestamps: true,
  });

  // TRENDS.LP POST
  $.post('/user/trends.lp', data, function(resp) {

    $.each(resp, function(id, object) {

      // SUM TO TOTAL
      if (total>0) {
        let totVal = 0;
        for (let l = 0; l < object.length; l++) {
           totVal += object[l];
        }
          result.push(trendsName[id],totVal);

      // NO TOTAL
      } else {
        result.push(trendsName[id],object);
      }
    });
 
  });
   
  return result;

}

My problem I can't iterate on the array on the function:

for example with


//last day
let day=getdata(classImage,-1,0,1);

this don't work. Lentgth return 0...

for (let i = 0; i < day .length; i++) {
console.log(day[i])
}

however a console.log of day show all result...   and a length. I gess there is something with scope/timelaps but I try also in jquery, with map... all same.

Code:

Array []
​
0: "PV - Active Energy No reset"
​
1: 16854
​
2: "General- Active Energy No reset"
​
3: 19329
​
length: 4
​
<prototype>: Array []

If our so nice admin could help me a bit, greatly appreciated.
