为了醒目,在中间加入地图,效果如下:
使用百度echarts制作可视化大屏——加入地图
地图由3部分组成,1、普通的圆点,2、中心原点(这里直接取top5代替),3、地理位置标记,显示具体的值;
为了显示地图,先引入china.js(echarts官网或者百度看源文件,到处都是),然后定义地理位置信息,代码如下:
var geoCoordMap = {

};
然后根据地理位置赋值,虚拟数据,代码如下:
var mapData=[];
for(key in geoCoordMap)
{
    var geoCoord = geoCoordMap[key];
    mapData.push({name:key,value:geoCoord.concat((Math.random()*1000).toFixed(2))});
}
然后做图就行了。
map_chart = echarts.init(document.getElementById_x('map'));
map_option = {
    title : {show:false},
    tooltip : {
        trigger: 'item',
        formatter: function(params) {
                if (typeof(params.value)[2] == "undefined") {
                    return params.name + ' : ' + params.value;
                } else {
                    return params.name + ' : ' + params.value[2];
                }
         },
         textStyle: {
