一、通用组件使用方式
1. 引入依赖
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width"> <title>趋势图-未来一周气温变化趋势</title> </head> <body> <div id="chart" style="width: 100%;height:100%;"></div> <script src="http://cdnjs.cloudflare.com/ajax/libs/echarts/4.8.0/echarts.min.js"></script> </body> </html>
2. 绘制图表
var myChart = echarts.init(document.getElementById('chart'));
var option;
option = {
