一、如图所示

二、页面引入echarts

//引入 echarts 主模块
import * as echarts from 'echarts/lib/echarts';
//引入折线图、柱状图
import 'echarts/lib/chart/line';
import 'echarts/lib/chart/bar';
//引入提示框组件、标题组件、工具箱组件
import 'echarts/lib/component/tooltip';
import 'echarts/lib/component/title';
import 'echarts/lib/component/toolbox';
import 'echarts/lib/component/legend';

三、设置标签

<div id="echartReal" style="width: 100%; height: 300px"></div>

四、代码封装

echartRealQuery(obj) {
    console.log("过去24小时实况数据", obj)
    let objWinds = obj.windS;
    let objWindd = obj.windD;
    let newWindData = [];
    let deg = null;
    for(let i = 0; i < objWinds.length; i++){
        if(objWindd[i] == "北风"){
            deg = 0;
        }else if(objWindd[i] == "东北风"){
            deg = 45;
        }else if(objWindd[i] == "东风"){
            deg = 90;
        }else if(objWindd[i] == "东南风"){
            deg = 135;
        }else if(objWindd[i] == "南风"){
            deg = 180;
        }else if(objWindd[i] == "西南风"){
            deg = 225;
        }else if(objWindd[i] == "西风"){
            deg = 270;
        }else if(objWindd[i] == "西北风"){
            deg = 315;
        }
        newWindData.push({
            value: objWinds[i],
            symbolRotate: 180 - deg,
            name: objWindd[i]
        });
    }
	echarts.init(document.getElementById('echartReal')).setOption({
