echarts高度自适应

HTML

Css #eachar-style{ width:100%; }

js

//初始化eacher实例

var myRowChart = echarts.init(document.getElementById('eachar-style'));

//设置自动高度

//返回数据的数组形式

let lengValue=res.data.goodsname;

//数组总长度* 每个子元素的高度

let heightauto=lengValue.length * 40 ;

//获取eacher中deom的结点 ==>getDom();

myRowChart.getDom().style.height = heightauto + "px";

myRowChart.setOption({

        title: {
            text: '购买频率'
        },
