Question

我正在尝试绘制HighCharts - Polar wind Rose Chart

参考：http://www.highcharts.com/demo/polar-wind-rose

但是当我检查我的chrome的控制台时，图表没有得到绘图我发现了这个错误 未捕获的TypeError：无法读取未定义的属性“0”

无法理解为什么会这样

我的JS代码：

function createWindRoseChart(divID, tableID, graphTitle) {
    var chart = new Highcharts.Chart({
        data: {
            table: tableID,
            startRow: 1,
            endRow: 10,
            endColumn: 8
        },
        chart: {
            polar: true,
            type: 'column',
            renderTo: divID,
            backgroundColor: 'rgba(255, 255, 255, 0.1)'
        },

        title: {
            text: graphTitle
        },

        subtitle: {

        },

        pane: {
            size: '85%'
        },

        legend: {
            reversed: true,
            align: 'right',
            verticalAlign: 'top',
            y: 100,
            layout: 'vertical'
        },

        xAxis: {
            tickmarkPlacement: 'on'
        },

        yAxis: {
            min: 0,
            endOnTick: false,
            showLastLabel: true,
            title: {
                text: 'Frequency (%)'
            },
            labels: {
                formatter: function () {
                    return this.value + '%';
                }
            }
        },

        tooltip: {
            valueSuffix: '%',
            followPointer: true
        },

        plotOptions: {
            series: {
                stacking: 'normal',
                shadow: false,
                groupPadding: 0,
                pointPlacement: 'on'
            }
        }
    });
}

其通话功能

createWindRoseChart('divCRATicketType', 'freq', 'Calls Open');
