<template><view class="container notice-list"><view><view class="aa" id="main" style="width: 500px; height: 400px;"></view></view></view>
</template><script>import * as echarts from 'echarts';export default {data() {return {myChart: null}},onShow() {},onLoad() {},onReady(){// 注意调用顺序，先初始化echarts才给echarts赋值this.initEcharts()this.setEchartsOption()},methods: {// 初始化echartsinitEcharts() {var chartDom = document.getElementById('main');// 将创建的echarts示例放到vue的data中，这样在这个界面就想到于全局配置了this.myChart = echarts.init(chartDom);},// 配置echarts的option，展示数据图表setEchartsOption() {// 这里可以发送axios请求，然后通过响应的数据赋值给对应的x轴和y轴即可，由于这里没有于后端联调，所以简单请求判断一下，// 请求后端大概也是这个过程var option;option = {tooltip: {trigger: 'axis',axisPointer: {type: 'shadow'}},grid: {left: '3%',right: '4%',bottom: '3%',containLabel: true},xAxis: [{type: 'category',data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'],axisTick: {alignWithLabel: true}}],yAxis: [{type: 'value'}],series: [{name: 'Direct',type: 'bar',barWidth: '60%',data: [10, 52, 200, 334, 390, 330, 220]}]};option && this.myChart.setOption(option);},},}
