1.自定义样式series加一项

   {
        type: "scatter",
        coordinateSystem: "cartesian2d",
        symbolSize: 50,
        symbol: "pin",
        symbolRotate: dzVal < 0 ? -270 : 270,
        itemStyle: {
          color: "#FFF",
          borderColor: "#26FDF5",
          borderWidth: "3",
        },
        label: {
          normal: {
            show: true,
            position: "inside",
            offset: [0, 4],
            color: "#000",
            fontWeight: "bold",
          },
        },
        data: [
          {
            name: "达州市",
            value: [dzVal, "达州市"],
          },
        ],
      },

隐藏原本样式
data[i].item

if (item.adname === '达州市') {
                         dzVal = item.zks
                         item.itemStyle = {
                                color: "#26FDF5",
                            };
                            item.label = {
                                show: false,
                            };
                     }
