前言：
1，报表连接：http://gallery.echartsjs.com/editor.html?c=xrJZ60TVIg
2，echats 制作报表中，使用地图的展示样式，发现地图上的显示数据不符合本意，地图中默认显示：区域：经纬度，数值。
1，先看下截图：
文章图片
如图中 成都 省 显示就会出现：成都省，123.12,45.22,100；
【echarts 使用案例（针对map地图中显示数据格式化）】
如果你这不是你所需要的需要自定义显示的样式，可以参考下面的解决方法；

}代码片段中标注为红色的部位 是需要增加格式化 函数的，这块代码我拿出来单独 解释。
tooltip: {
trigger: 'item'
},在tooltip 属性中 增加一个属性[formatter];
最终结果：
tooltip:{
trigger:'item',
formatter:function(params){
//这里可以获取到你的数据params
//处理数据，返回显示结果。
return '23';
}
}
情况一：
如果存在地图上数据显示正常但是 右边柱状图显示有问题，需要特别注意componentSubType 这个参数，
可以在控制台输出params 可以看到componentSubType 这个属性，使用它来区分数据在地图与柱状图上的显示。
