在1个组件中实现5个图形

Question

我需要使用amCharts库在1个组件中实现5个图，但是我对5个图使用相同的代码，仅更改了变量命名法。但是1和2图是正确的，图是正确的，3、4和5没有任何数据。

 ngAfterViewInit() {
    let chart = am4core.create("chart_o2", am4charts.XYChart);
    chart.paddingRight = 20;

    let data = [];
    let visits = 10;
    for (var i = 1; i < 50000; i++) {
      visits += Math.round((Math.random() < 0.5 ? 1 : -1) * Math.random() * 10);
      data.push({ date: new Date(2018, 0, i), value: visits });
    }

    chart.data = data;

    let dateAxis = chart.xAxes.push(new am4charts.DateAxis());
    dateAxis.renderer.grid.template.location = 0;
    dateAxis.minZoomCount = 5;

    dateAxis.groupData = true;
    dateAxis.groupCount = 500;

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

    let series = chart.series.push(new am4charts.LineSeries());
    series.dataFields.dateX = "date";
    series.dataFields.valueY = "value";
    series.tooltipText = "{valueY}";
    series.tooltip.pointerOrientation = "vertical";
    series.tooltip.background.fillOpacity = 0.5;

    chart.cursor = new am4charts.XYCursor();
    chart.cursor.xAxis = dateAxis;

    let scrollbarX = new am4core.Scrollbar();
    scrollbarX.marginBottom = 20;
    chart.scrollbarX = scrollbarX;
  }
