javascript - Angular 旭日图

Question

您好，我正在使用 Highchart 制作旭日图，但是出现错误，我无法找出代码中的错误，所以请帮助我。

我的 HTML 代码是:

<highcharts-chart
    [Highcharts]="highcharts1"
    [options]="chartOptions1"
    style="width: 100%; height: 200px; display: block;">
  </highcharts-chart>

而Ts代码是

chartData = [
        {
            id: '2.13',
            parent: '1.3',
            name: 'Southern Asia'
        }
        ];
 highcharts1: typeof Highcharts = Highcharts;
    chartOptions1: Highcharts.Options = <any> {
        chart: {
            height: '100%'
        },
        title: {
            text: 'World population 2017'
        },
        subtitle: {
            text: 'Source <href="https://en.wikipedia.org/wiki/List_of_countries_by_population_(United_Nations)">Wikipedia</a>'
        },
        series: [{
            type: "sunburst",
            data: this.chartData,
            allowDrillToNode: true,
            cursor: 'pointer',
            dataLabels: {
                format: '{point.name}',
                filter: {
                    property: 'innerArcLength',
                    operator: '>',
                    value: 16
                }
            },
            levels: [{
                level: 1,
                levelIsConstant: false,
                dataLabels: {
                    filter: {
                        property: 'outerArcLength',
                        operator: '>',
                        value: 64
                    }
                }
            }, {
                level: 2,
                colorByPoint: true
            },
            {
                level: 3,
                colorVariation: {
                    key: 'brightness',
                    to: -0.5
                }
            }, {
                level: 4,
                colorVariation: {
                    key: 'brightness',
                    to: 0.5
                }
            }]

        }]
    };

您需要导入并初始化sunburst模块:

import * as Highcharts from 'highcharts';
import HC_sunburst from 'highcharts/modules/sunburst';
HC_sunburst(Highcharts);
