图表线不绘制

Question

我有一个典型的场景，在图表行中没有为我画画。

当我尝试获取相同的数据并将其放入jsfiddle时，它似乎正在工作。

附上我的应用程序中的屏幕截图，该屏幕截图不显示该行但仅显示点。

以下是我正在谈论的fiddle

$(function () {
    $('#chartContainer').highcharts({chart: {
            renderTo: 'chartContainer',
            type: 'spline',
            marginTop:50,
            spacingBottom: 5,
            marginBottom: 100
        },
        credits: {
              enabled: false
          },
        title: {
            text: 'Product health'

        },
        subtitle: {
            text: ''
        },
        xAxis: {
            type: 'datetime',
            minTickInterval: 24 * 3600 * 1000,
            dateTimeLabelFormats: { 
                month: '%e %b',
                year: '%b'
            }
        },
        yAxis: {
            min: 0,
            max:100,
            tickInterval:10,
            title: {
                text: 'Passrate'
            }
        },
        legend: {
                        title: {
                            text: '<span style="font-size: 9px; color: #666; font-weight: normal">To toggle between different branches click on the branch names in the legend</span>',
                            style: {
                                fontStyle: 'italic'
                            }
                        },
                        layout: 'horizontal'
                    },
        tooltip: {
            formatter: function() {
                     return 'Branch: <b>'+ this.series.name +
                        '</b><br/>Date: '+ Highcharts.dateFormat('%e %b',this.x)+
                            '</b><br/>Pass rate: '+ this.y +'%'+
                             '</b><br/>Pass count: '+  this.point.options.passCount+
                         '</b><br/>Total count: '+  this.point.options.totalCount;
            }
        },
         plotOptions: {
            spline: {
                dataLabels: {
                    enabled: 'True',
                    format: '{y} %'
                },
                enableMouseTracking: true,
                crop: 'false',
                overflow: 'none'
            }
        },
        series: [{name: 'xyz', data:[{x: Date.UTC(2013,10,2),y: 100,passCount: 4,totalCount: 4},{x: Date.UTC(2013,10,6),y: 100,passCount: 3,totalCount: 3}]}]

    });
});
