散点图+地图两组数据间的关系表示echarts scatter配置项内容和展示

如何让同一个点的两个数据的气泡大小相关显示？并且两组数据组内气泡大小也相关？

      var uploadedDataURL = "/asset/get/s/data-1482313846656-r11tlRwEx.json";

function convertData(sourceData) {
    return [].concat.apply([], $.map(sourceData, function(test, index) {
        return {
            name: test.mypoint,
            value: [test.jingdu, test.weidu, test.num1, test.num2]
        };
    }));
}

var option = {
