官網
一切以官網為主，今天我們需要基於這個地圖 來做。
官網js地址： https://github.com/apache/incubator-echarts/tree/master/dist
這個目錄下有很多js文件，我們選擇echarts.js和extension下的bmap.js， 最好把整個目錄克隆下來，然后復制這2個文件到你的目錄下。
option的參數配置
這里我要介紹下tooltip這個參數，這個參數控制了這個功能：當你的鼠標移動到高亮的那個點時，要想顯示什么內容，就必須通過這個參數來控制顯示內容。如果你什么都配置，那么咱們使用的這個地圖就一直顯示固定內容。
官網文檔地址：https://www.echartsjs.com/zh/option.html#tooltip.formatter
參考官網文檔，我們得知，要想顯示我們需要的內容，就需要通過 formatter 函數來控制返回內容，從而才能夠顯示，那不得不介紹下這formatter 接受的幾個參數了。
formatter: function (params, ticket, callback) { }
- params 這個是當前這個元素對象，如，這個對象有value值，那么就 params.value ，如這個對象有name值，那么就params.name ,然后return params.name 就能顯示這個元素name這個值。
- ticket 是異步回調標識，配合第三個參數 callback 使用。
- callback 是異步回調，在提示框浮層內容是異步獲取的時候，可以通過 callback 傳入上述的 ticket 和 html 更新提示框浮層內容。
代碼先睹為快
前提條件：
后端接口返回的數據必須是以下這樣的
[
{"name":"贛州市","value":[ 經度,維度, 數值1,數值2 ] },
{"name":"天津市","value":[ 經度,維度, 數值1,數值2 ] },
]
多說一句，經緯度可以根據百度這個接口來獲取，但是僅供參考，因為有些城市的經緯度不准。
