angular11给Echarts添加点击事件，无脑抄代码的时候到了~~ 超好用

关于引入Echarts的方法在此

直通车在此

接下来就是添加点击事件，获取X轴的数据

<div echarts #charts [options]="chartOption" class="charts"></div>

import { NgxEchartsService } from 'ngx-echarts';
  @ViewChild('charts', { static: false }) charts: ElementRef;
constructor(
    private es: NgxEchartsService
  ) { }

this.es.getInstanceByDom(this.charts.nativeElement).setOption(this.chartOption)
 let myChart = this.es.getInstanceByDom(this.charts.nativeElement)
      myChart.getZr().on('click', function (params) {
        var pointInPixel = [params.offsetX, params.offsetY];
        if (myChart.containPixel('grid', pointInPixel)) {
          /*此处添加具体执行代码*/
          var pointInGrid = myChart.convertFromPixel({ seriesIndex: 0 }, pointInPixel);
          //X轴序号
          var xIndex = pointInGrid[0];
          //获取当前图表的option
          var op = myChart.getOption();
          //获得图表中我们想要的数据---懒得写循环了，复制了一下，下面就不简写了，默认说我们的折现有三条吧
          var xValue = op.xAxis[0].data[xIndex];
          var value = op.series[0].data[xIndex];
          var name = op.series[0].name;
          var value1 = op.series[1].data[xIndex];
          var name1 = op.series[1].name;
          var value2 = op.series[2].data[xIndex];
          var name2 = op.series[2].name;
          console.log(op);
          console.log('xValue: '+xValue + ", series[0].name0: "+name +' , value: '+ value + "%");
          console.log('xValue: '+xValue + ", series[1].name0: "+name1 +' , value1: '+ value1 + "%");
          console.log('xValue: '+xValue + ", series[2].name0: "+name2 +' , value2: '+ value2 + "%");
        }
      });
