原因是：使用web的要设置 echartsH5

:echartsH5="true" 

<template><view class="charts-box"><view class="chart-title"> 趋势</view><qiun-data-chartstype="column":eopts="eopts":chartData="chartData":background="backc":echartsH5="true" :echartsApp="true"/></view>
</template>
...
data() {return {chartData: {},backc: 'rgb(254,254,254)',eopts: {dataLabel:false,legend: {show:false},xAxis: {type: 'category',disableGrid: true,axisLine: {show: false}},yAxis: {show:false,axisLine: {show: false}},series: []}}},
