I\'m using push function in javascript.

for(var i=0; i<3; i++) {

    chartData.push({

        date: new Date(year_s,mon_s,date_s,hr_s,mi         


        

Answer 1

You have to make it in two steps :

var chartData = [];
for(var i=0; i<3; i++) {
   // 1. create the object
   var d =  { 
      date: new Date(year_s,mon_s,date_s,hr_s,min_s,sec_s),
      customBullet: show_annotations,
      balloonTextField: "testtesttest"
   };
   // 2. then assign the visits_i property
   d['visits_'+i] = chartData1[selection[i]][j].value; 
   chartData.push(d);
}
