状元村建设官方网站,网站模板下载之后怎么做,查网站流量查询工具,任丘网站制作1.把echarts 在 methods 封装成一个方法mounted 在中调用
折线图 和柱状图
mounted调用下边两个方法 mounted(){//最早获取DOM元素的生命周期函数 挂载完毕console.log(mounted-id , document.getElementById(charts))this.line()this.pie()},methods里边的方法

折线图 和柱状图
mounted调用下边两个方法 mounted(){//最早获取DOM元素的生命周期函数 挂载完毕console.log(mounted-id , document.getElementById(charts))this.line()this.pie()},methods里边的方法
line() {// 基于准备好的dom初始化echarts实例var myChart echarts.init(document.getElementById(charts));// 绘制图表myChart.setOption({tooltip: {//提示框组件trigger: axis,},legend: {},toolbox: {feature: {// dataZoom: {// yAxisIndex: none// },// restore: {},saveAsImage: {}}},xAxis: {//x轴数据data: [120, 200, 150, 80, 70, 110, 130],},yAxis: {//y轴会自动创建数据},series: [//图表内容{name: 销售额,type: line,data: [120, 200, 150, 80, 70, 110, 130],,smooth: true,//是否平滑曲线显示},{name: 销售量,type: bar,data: [120, 200, 150, 80, 70, 110, 130],}]});},饼图 pie(){let myChart echarts.init(document.getElementById(pie));myChart.setOption({tooltip: {trigger: item},legend: {top: 5%,left: center},series: [{name: Access From,type: pie,radius: [40%, 70%],avoidLabelOverlap: false,itemStyle: {borderRadius: 10,borderColor: #fff,borderWidth: 2},label: {show: false,position: center},emphasis: {label: {show: true,fontSize: 40,fontWeight: bold}},labelLine: {show: false},data: [{ value: 1048, name: Search Engine },{ value: 735, name: Direct },{ value: 580, name: Email },{ value: 484, name: Union Ads },{ value: 300, name: Video Ads }]}]});},注意的地方:created调用location事件时获取dom对象是不行的因为在created钩子函数中是获取不到dom的我们可以使用mounted钩子替换成created钩子
从后端取数据
发现后端给我们返回的不是echarts的格式 这个时候我们做一个操作 下一步操作 遍历内容 数据格式转换
最后一步 在echarts柱状图或者折线图里边去显示这些数据 methods:{// -----获取图标动态数据async format(){let res await this.$api.format()console.log(获取图标动态数据---,res.data);console.log(res.data.result.data.sale_money);//[{}{}]// 折线图 柱状图数据格式:[xx,xx,xx]// 获取x轴的数据名称let arr res.data.result.data.sale_money;//拿到数据let arrx []let total []let money []arr.forEach((ele){//ele是取每一项arrx.push(ele.name)total.push(ele.num)money.push(ele.total_amount)})console.log(arrx);console.log(total);console.log(money);this.line(arrx,money,total)},//绘制图表--折线------------------line(arrx,money,total) {// 基于准备好的dom初始化echarts实例var myChart echarts.init(document.getElementById(charts));// 绘制图表myChart.setOption({tooltip: {//提示框组件trigger: axis,},legend: {},toolbox: {feature: {// dataZoom: {// yAxisIndex: none// },// restore: {},saveAsImage: {}}},xAxis: {//x轴数据data:arrx,},yAxis: {//y轴会自动创建数据},series: [//图表内容{name: 销售额,type: line,data:money,smooth: true,//是否平滑曲线显示},{name: 销售量,type: bar,data: total,}]});},},饼状图取数据 发现 数据循环遍历数据格式转换 let pieData []arr.forEach((ele){//ele是取每一项//饼图--对象数据let obj{}obj.name ele.name;obj.value ele.total_amount;pieData.push(obj)//[{name:,value:},{},{}]})console.log(饼图,pieData);饼图最后一步 在echarts柱状图或者折线图里边去显示这些数据 //绘制饼图pie(pieData) {var myChart echarts.init(document.getElementById(pie));var option;option {tooltip: {trigger: item,formatter:{a}br/{b}:{d}%},legend: {orient: vertical,left: left},series: [{name: 产品销售额,type: pie,radius: 50%,data:pieData,// data: [//[{},{}]// { value: 1048, name: 审议 },// { value: 735, name: 淘宝 },// { value: 580, name: 京东 }// ],emphasis: {//高亮配置itemStyle: {shadowBlur: 10,shadowOffsetX: 0,shadowColor: rgba(0, 0, 0, 0.5)}}}]};option myChart.setOption(option);},全部代码
