首先，在组件中定义一个数据数组，例如：

export class ChartComponent implements OnInit {
  chartData: any[] = [
    {
      "country": "USA",
      "visits": 3025
    },
    {
      "country": "China",
      "visits": 1882
    },
    {
      "country": "Japan",
      "visits": 1809
    },
    {
      "country": "Germany",
      "visits": 1322
    },
    {
      "country": "UK",
      "visits": 1122
    },
    {
      "country": "France",
      "visits": 1114
    },
    {
      "country": "India",
      "visits": 984
    }
  ];

  chart: am4charts.XYChart;

  ngOnInit() {
    this.createChart();
  }

  createChart() {
    this.chart = am4core.create("chartdiv", am4charts.XYChart);

    this.chart.data = this.chartData;

    // chart code block...
  }

然后在 AMCharts 代码块中使用该数组，例如：

createChart() {
  this.chart = am4core.create("chartdiv", am4charts.XYChart);

  this.chart.data = this.chartData;

  let categoryAxis = this.chart.xAxes.push(new am4charts.CategoryAxis());
  categoryAxis.dataFields.category = "country";
  categoryAxis.renderer.grid.template.location = 0;
  categoryAxis.renderer.minGridDistance = 30;

  let valueAxis = this.chart.yAxes.push(new am4charts.ValueAxis());

  let series = this.chart.series.push(new am4charts.ColumnSeries());
  series.dataFields.valueY = "visits";
  series.dataFields.categoryX = "country";
  series.name = "Visits";
  series.columns.template.tooltipText = "{categoryX}: [bold]{valueY}[/]";
  series.columns.template.fillOpacity = .8;

  // chart code block...
}

这样就能在 AMCharts 中成功使用数据数组了。
