通过颜色映射销量echarts 地图配置项内容和展示

根据自己的喜好进行配置，也可以封装一个函数，地图需要第三方脚本，可以官网首页下载。

      // 随机0-1000的数
function randomData() {
    return Math.round(Math.random()*1000);
}
// legend内容
var legendData=['空调','太阳能','洗衣机','冰箱'];
// legend自定义颜色 不设置有默认色
var legendColor=['blue','gray','#000','cyan'];
// 映射颜色  不设置有默认色
var visColor=["#ffffff","#e8192f","#d6664d","#B9044E","#f0ba2e","#d3ce2b","#169A7f","#0b6573","#1BB3c8"];
// seriesData Array [{name:'',type:'map',mapType:'china',
//           label: { normal: {show: true},emphasis: { show: true}},data:[{name:'',value:''},...]},{...}]
