html中:
<div class="charts1"/> <div class="charts2"/> <div class="charts3"/> <div class="charts4"/> <div class="charts5"/> <div class="charts6"/> <div class="charts7"/>
数据处理就不用提了。嗯,直接画图:
// 画 折线图 drawLine() { // 数据处理的方法 this.dealEchartsData() var myChartsArr = [] for (var i = 1; i <= 7; i++) { this.myCharts = this.$echarts.init(document.getElementsByClassName('charts' + i)[0]) myChartsArr.push(this.myCharts) var option = this.commonOption(this.myCharts, this.adnormalTypeSummery[i - 1], this.destArrAll[i - 1]) // 为echarts对象加载数据 true 防止echarts数据叠加!!! this.myCharts.setOption(option, true) } window.onresize = function() { // 自适应 for (var j = 0; j < myChartsArr.length; j++) { if (myChartsArr[j].resize()) { myChartsArr[j].resize() } } } },
公用部分:
// option 主体 commonOption(myCharts, titleText, destData) { var option = { title: { text: titleText }, tooltip: { trigger: 'axis', confine: true }, legend: { type: 'scroll', width: '90%', top: '13%' }, grid: { left: '3%', right: '4%', bottom: '2%', containLabel: true }, toolbox: { right: '20', feature: { saveAsImage: {} } }, xAxis: { type: 'category', boundaryGap: false, data: this.monthName }, yAxis: { type: 'value' }, series: destData } return option }
离开该页面时候摧毁:
destroyed() { if (this.myCharts) { this.myCharts.clear() this.myCharts.dispose() window.onresize = null }
补充知识:Vue + Echarts 图表展示 及 动态渲染
准备工作
安装echarts依赖
npm install echarts --save-dev
引入
(main.js) import echarts from 'echarts' Vue.prototype.$echarts = echarts;
开始撸代码
<template> <div class="peopleWrap"> <h3> <i class="el-icon-position"></i> 出入人员总数{{peopleSumTotal}} </h3> <div id="peopleSum" style="width: 180px;height: 270px"></div> </div> </template> <script> export default { // 接受父组件传来的参数【父传子props】 props: ["peopleSumTotal"], data() { return { peopleSumTotalArr: [] }; }, watch: { // 监听参数变化 peopleSumTotal: { handler(newVal, oldVal) { if (newVal != 0) { console.log(newVal); this.peopleSum(newVal); } } } }, methods: { peopleSum(newVal) { // 引入 echarts var echarts = require("echarts"); let peopleSum = echarts.init(document.getElementById("peopleSum")); //echsrts点击事件 peopleSum.on("click", function(param) { console.log(param); console.log(param.data.name); console.log(param.data.value); console.log(param.data.userDefined); //$emit的第一个为传的参的名字,第二个为传的值 【子传父 this.$emit】 _this.$emit("peopleSumtoparent", param.data); }); //接受动态数据时需要在 this.$nextTick(()=>{})展示 this.$nextTick(() => { let obj = {}; obj.value = newVal; obj.name = newVal; this.peopleSumTotalArr.push(obj); let option = { legend: { orient: "vertical", left: 10, data: [""] }, series: [ { type: "pie", radius: ["50%", "70%"], avoidLabelOverlap: false, itemStyle: { // 普通样式。 normal: { // 点的颜色。 color: "#6998f7" }, // 高亮样式。 emphasis: { // 高亮时点的颜色。 color: "#6998f7" } }, label: { normal: { show: true, position: "center", textStyle: { fontSize: "20" } } }, labelLine: { normal: { show: false } }, data: this.peopleSumTotalArr //动态图表展示 } ] }; console.log("option", option); peopleSum.setOption(option); }); } }, mounted() {} }; </script> <style lang="scss" scoped> </style>
以上这篇浅谈vue单页面中有多个echarts图表时的公用代码写法就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持三水点靠木。
