asp.net mvc 之显示24小时折线对比数据

我这里因为没有数据，所以就给出个大概图吧，实现的结果是，a的值和b的值都在图中显示，两者进行对比

前台代码：

 function getzhe() {
            var yset = new Array();
            var x1 = new Array();
            var x2 = new Array();
            $.ajax({
                type: 'get',
                url: "/DeFault/GetHH",
                datatype: 'json',
                success: function (data) {
                    data = $.parseJSON(data);
                    for (var i = 0; i < data.length; i++) {
                        yset[i] = data[i].day_date;
                        x1[i] = parseInt(data[i]["count"]);
                        x2[i] = parseInt(data[i]["wh_count"]);
                    }
                    $('#lineChart').highcharts({
                        chart: {
                            type: 'area'
                        },
                        title: {
                            text: null
                        },
                        subtitle: {
                            text: ''
                        },
                        xAxis: {
                            categories:yset,
                            title: {
                                text: null
                            }
                        },
                        yAxis: {
                            min: 0,
                            title: {
                                text: '数量(次)',
                                align: 'high'
                            },
                            labels: {
                                overflow: 'justify'
                            }
                        },
                        tooltip: {
                            valueSuffix: '个'
                        },
                        plotOptions: {
                            bar: {
                                dataLabels: {
                                    enabled: true
                                }
                            }
                        },
                        legend: {
                            layout: 'vertical',
                            align: 'right',
                            verticalAlign: 'top',
                            x: -40,
                            y: 100,
                            floating: true,
                            borderWidth: 1,
                            backgroundColor: '#FFFFFF',
                            shadow: true
                        },
                        credits: {
                            enabled: false
                        },
                        series: [
                            {
                                name: "总话务",
                                showInLegend: false,
                                data: x1
                            },
                            {
                                name: "外话",
                                showInLegend: false,
                                data: x2
                            }
                        ]
                    });
                }
            });
        }
