3. HTML引入方式
本地引入
script srcecharts-5.4.3.min.js/scriptCDN引入
script srchttps://cdn.bootcdn.net/ajax/libs/echarts/5.4.3/echarts.min.js /script4. 基本概念
echart echarts.init(document.getElementById(container)); // 初始化类
option { // 配置类title: { // 标题text: Website,left: center},tooltip: { // 提示框trigger: item},legend: { // 配置图例的显示和位置orient: vertical,left: left},xAxis: { // 配置X轴直角坐标才会有type: category,data: []},yAxis: { // 配置Y轴直角坐标才会有type: value},series: [ // 配置图表的数据和绘制方式{type: , // 图表类别如折线图linedata: [ // 图表数据可以是数组或对象数组]}]
};
echart.setOption(option); // 渲染图形二、常见图表
