[Solved]-set a symbol marker with highchart-Highcharts

the line:

series.data = value;

overwrite whatever you wrote in

var series = { 
        data: [ {

i am not sure what you have in the "data" variable, but assume its is as [key:[val1,val2,...],...], try replace "series.data = value" with the following:

var list= new array();
foreach(var v as value){
   if (v==0){ //or what ever condition you need to use a different mark 
      var m={
            y: v,
            marker: {
                symbol: 'url(img/fail.png)'
            }};
      list.push(m);       
   } 
   else{
      list.push(v);
   }
}
series.data = list;
