How to call api again after clearing interval

Question

I am getting num1 and num2 value from service call. I am trying reset interval after clearing it but it does not work this way. I have also tried other ways mentioned in stackoverflow. Nothing works.

 d3.json('/service/dates', function(error,dates) {

  var dran = dates;

  if(dates != null){

  sDt = new Date(dates.st);

  eDt = new Date(dates.et);

  var i = 0;

  var start = function(){

    if (sDt > eDt) {

      clearInterval(interval);

      flag = true;

      console.log(fromDt);

      console.log(toDt);

      interval = setTimeout(start,200);

      $('.wrapper').trigger('newPoint');

      return;



    }

    var sDate = sDt.toISOString(); 

    var eDate = new Date(sDt.setMinutes(sDt.getMinutes() + 30)).toISOString();



    //Calling the api for graph values

    d3.json("/service/dat?s=" +sDate+ "&e=" +eDate, function(error,results) {

      if(results != null){



          numbers = numbers.concat(results.numbers);

          values[values.length] = results.values;

      }

    });

     i++;

  }

  var interval = setInterval(start,10); 

  }

});

 $('.wrapper').on('newPoint', function(){

    if(flag){

       if(count!=values.length){

        tick(values[count]);

        count++;

      }

    }   

  });

Put the entire API call inside a named function. Then call that from the start() function to restart everything.

function doAPILoop() {
  d3.json('/service/dates', function(error, dates) {
    var dran = dates;
    if (dates != null) {
      sDt = new Date(dates.st);
      eDt = new Date(dates.et);
      var i = 0;
      var start = function() {
        if (sDt > eDt) {
          clearInterval(interval);
          $('.wrapper').trigger('newPoint');
          doAPILoop();
          return;
        }
        var sDate = sDt.toISOString();
        var eDate = new Date(sDt.setMinutes(sDt.getMinutes() + 30)).toISOString();

        //Calling the api for graph values
        d3.json("/service/dat?s=" + sDate + "&e=" + eDate, function(error, results) {
          if (results != null) {

            numbers = numbers.concat(results.numbers);
            values[values.length] = results.values;
          }
        });
        i++;
      }
      var interval = setInterval(start, 10);
    }
  });
}

doAPILoop();
