echarts绘制省份地图并添加自定义标注
效果图
在main.js中引入地图
import echarts from 'echarts'
Vue.prototype.$echarts = echarts;
省份是动态引入的，在.vue文件中
html部分
<div id="province_map_box">
<div id=province_map"></div>
</div>
css部分
<style lang="scss" scoped>
#province_map_box {
height: 500px;
position: relative;
}
#province_map_box #province_map{
height: 100%;
}
#province_map_box .province_map_logo{
position: absolute;
top: 0;
left: 0;
width:45px;
}
</style>
<style lang="scss">
#province_map.tooltip_style{
line-height:1.7;
overflow: hidden;
}
#province_map.tooltip_left{
float: left;
}
#province_map.tooltip_right{
float: right;
}
</style>

注： echarts v4.2.1版本安装后会有地图json文件
