chartist to display nice pie...

Thanks for your lp file.

I tried to do sum of the value, but can't get length value, still 0 for result. however I can see the result value as array type in console...
I tried lots of solution with each, for... without success. Any idea ?

Code:

function readTrend( listeId, dayBefore, dayBase )
{

  var data = JSON.stringify({
    dates_curr: {
      start: getdate(dayBefore),
      end: getdate(dayBase)
    },
    ids: listeId,
  });
  var result = [];
  var totVal=[];
 
  $.post('/scada-vis/trends/fetch', { data }, function(trends) {

    trends = JSON.parse(trends);
    $.each(trends, function(_, trend) {
      result.push(trend.data);
    });

  });
 
  return sum(result);

}

Code:

function sum(array) {
 
//test each
  let totVal = 0
  console.log(array[1]);
  let newArray=new Array();
  newArray=array;
 
   $.each(newArray, function(_, lined) {
      console.log(lined.data);
    });
 
// test for
for (let l = 0; l < array.length; l++) {
   console.log('hello');
   var sum = 0;
    for (let k = 0; k < array[l].length; k++) {
        sum += array[l][k];
    }
    //console.log(sum);
   totVal.push(sum);
    }
   
  return sum(result);
}

result array in console log. Also result[0] or result[1] or result[0][0]...don't work.

Code:

Array []
​
0: Array(24) [ 112, 112, 114, … ]
​
1: Array(24) [ 291, 173, 666, … ]
​
2: Array(24) [ 13, 14, 13, … ]
​
length: 3
​
<prototype>: Array []

----------

only solution I found is using inside the function

Code:

function readTrend( listeId, dayBefore, dayBase, total )
{

  var data = JSON.stringify({
    dates_curr: {
      start: getdate(dayBefore),
      end: getdate(dayBase)
    },
    ids: listeId,
  });
  var result = [];
  var totVal=[];
 
  $.post('/scada-vis/trends/fetch', { data }, function(trends) {

    trends = JSON.parse(trends);
    $.each(trends, function(_, trend) {
      if (total>0) {
        let totVal = 0
        for (let l = 0; l < trend.data.length; l++) {
           totVal += trend.data[l];
        }
          result.push(totVal);
       
      } else {
        result.push(trend.data);
      }
    });

  });
 
  return result;

}

However I can't understand why in the other solution the lenght and [x] don't work
