The Js Class in which it shows error is

// JavaScript Document

var GraphClass =

    gauges:[],
    cal:0,
    createGauge:function(name, label, min, max)
    {

        }

       var range = config.max - config.min;
       config.yellowZones = [{ from: config.min + range*0.75, to: config.min + range*0.9 }];
       config.redZones = [{ from: config.min + range*0.9, to: config.max }];
       GraphClass.gauges[name] = new Gauge(name + "GaugeContainer", config); // **In this line it shows error in eclipse emulator but correct in browsers**
       GraphClass.gauges[name].render();
   },
createGauges:function()
{
    GraphClass.createGauge("cb_graph", "Calories Burn",0,2600);
    GraphClass.createGauge("cn_graph", "Calories Gain",0,localStorage.getItem("DailyRequiredCalories"));

updateGauges:function()

    for (var key in GraphClass.gauges)

        var value = GraphClass.getRandomValue(GraphClass.gauges[key]);
        GraphClass.gauges[key].redraw(value);
    }
},
getRandomValue:function(gauge)
{
    var overflow = 0; //10;
    console.log(gauge.config.min+" - "+overflow+" + ( "+gauge.config.max+" - "+gauge.config.min+" + "+overflow*2+")*"+Math.random());
