ts中怎么写echarts,setOption?

Question

这段代码在ts中应该怎么优化,这边都画白线了

      myChart.setOption({
      tooltip: {
        trigger: "item",
        backgroundColor: "rgba(166, 200, 76, 0.82)",
        borderColor: "#FFFFCC",
        showDelay: 0,
        hideDelay: 0,
        enterable: true,
        transitionDuration: 0,
        extraCssText: "z-index:100",
        formatter: function(params:any, ticket:any, callback:any) {
          //根据业务自己拓展要显示的内容
          var res = "";
          var name = params.name;
          var value = params.value[params.seriesIndex + 1];
          res = "<span style='color:#fff;'>" + name + "</span><br/>数据：" + value;
          return res;
        }
      },
      backgroundColor:"#013954",
      visualMap: { //图例值控制
        min: 0,
        max: 1,
        calculable: true,
        show: true,
        color: ['#f44336', '#fc9700', '#ffde00', '#ffde00', '#00eaff'],
        textStyle: {
          color: '#fff'
        }
      },
      geo: {
        map: 'china',
        zoom: 1.2,
        label: {
          emphasis: {
            show: false
          }
        },
        roam: true, //是否允许缩放
        itemStyle: {
          normal: {
            color: 'rgba(51, 69, 89, .5)', //地图背景色
            borderColor: '#fff', //省市边界线00fcff 516a89
            borderWidth: 2
          },
          emphasis: {
            color: 'rgba(37, 43, 61, .5)' //悬浮背景
          }
        }
      },
      series: this.series
    });
