</template>
<script setup>
import * as echarts from 'echarts';
import { onMounted } from 'vue';
onMounted(() => {
getHotData()
})
const getHotData = () => {
// 基于准备好的dom,初始化echarts实例
var myChart = echarts.init(document.getElementById('main'));
// 绘制图表
myChart.setOption({
title: {
text: 'ECharts 入门示例'
},
tooltip: {},
xAxis: {
data: ['衬衫', '羊毛衫', '雪纺衫', '裤子', '高跟鞋', '袜子']
},
yAxis: {},

var myChart = echarts.init(document.getElementById('main'))

onMounted
