Question

 for(let i = 0; i<rlist.length;i++){
                    let radian1 = 90-rlist[i].r-30;//扇形的第一条边
                    let radian2 = 90-rlist[i].r;//扇形的第二条边
                    let oval = new AMap.Polygon({
                      path:this.sector(point,40,radian1,radian2),
                      strokeColor: "#ff8400",
                      strokeOpacity: "1",
                      strokeWeight: 1,
                      fillColor: "#ff8400",
                      fillOpacity: "0.3",
                      cursor:"pointer"
                    })
                    oval.on('click', this.polygonClick);
                    this.map.add(oval);
