使用eCharts做了一个中国地图的各地之间的线路连接

# 1.具体代码路径 #

[https://gallery.echartsjs.com/editor.html?c=x8DKVD1v2&v=4][https_gallery.echartsjs.com_editor.html_c_x8DKVD1v2_v_4]

# 2.js文件 #

[https://download.csdn.net/download/qq\_28198181/12250555][https_download.csdn.net_download_qq_28198181_12250555]

# 3.echarts.js修改的地方 #

用于切换地图js文件：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI4MTk4MTgx_size_16_color_FFFFFF_t_70][]

第44873行的 maptype 我从world切换成了china。

# 4.前端代码放置 #

我把它分为了3个部分：

##   1.导入JS文件 ##

这个就是导入要使用的代码地方

看是哪个地方需要导入就行

##   2.正文引用div ##

我引用了一个id为map 的 div **必须要定义宽和高  **否则会js报错找不到宽高的属性（在导入的js文件中）

##   3.script代码 ##

其实可以分为两个部分

第一个部分是 加载和显示：

也就是查找id 和 option部分

<script>
       var myChart = echarts.init(document.getElementById('map'));
        
       // 业务代码： 
    
        ........
    
       
      myChart.setOption(option);
    </script>

第二个部分是内容代码：

比如我用的是省会与省会之间的联系：

运行最后得出内容就是为：

这个是完整代码：
