这两天帮人搞了下中国范围内仓库量统计的需求，查了下echarts 里的文档找到类似的demo（链接：https://ecomfe.github.io/echarts-examples/public/editor.html?c=geo-map-scatter）

这里面有几个小东西，可能查文档的时候不好找到
1 visualMap 中 seriesIndex 对应的是对哪个series 进行渐变，若想两个都渐变，可以赋值位 seriesIndex： [0, 1]
2 中国地区不显示浮层，标记图标（飞机）显示浮层：
在上面的代码中向对应的series中 加入 tooltip:{show: false}
3 去掉背景中省份地址两个字
在geo中设置为
label: {
emphasis: {
show: false
}
},
4 更改标记图标为其他图片
在对应series中设置如这种的 symbol: 'image://https://pic.ulecdn.com/item/user_0102/desc20190115/1fb19e0cf39aafef_-1x-1.png'
其他的基本样式，如symbolSize或者itemStyle ,只要自己能在对应的series,geo,visualMap 中参考下就行，总而言之，用echart画图还是很炫酷的，不过就是查文档有时有时很麻烦，为了个需求，都找不到咋写api。因此这里也就小写下，这个geo渐变的基本需求，与大家分享下。
