                        var arryspot = [];
                        if (spotname.indexOf(',') != -1) {
                            arryspot = spotname.split(',');
                        }
                        else {
                            arryspot.push(spotname);
                        }
                        //series
                        var series = [];
                        for (var a = 0; a < arryspot.length; a++) {
                            var data = {
                                name: arryspot[a],
                                data: (function () {
                                    // generate an array of random data
                                    var data = [], time = (new Date()).getTime(), i;                                    for (i = -999; i <= 0; i++) {
                                        data.push([

                                            Math.round(Math.random() * 100)
                                        ]);
                                    }
                                    return data;
                                })()
