### Version 4.7.0 ### Reproduction link [https://www.echartsjs.com/examples/zh/editor.html?c=dynamic-data2](https://www.echartsjs.com/examples/zh/editor.html?c=dynamic-data2) ### Steps to reproduce 将随机数值函数修改为 function randomData() { now = new Date(); value = value Math.random() * 21 - 10; return { name: now.toString(), value: [ [now.getFullYear(), now.getMonth() 1, now.getDate()].join('/') " " [now.getHours(), now.getMinutes(), now.getSeconds()].join(':'), Math.round(value) ] }; } 将格式化日期修改为 tooltip: { trigger: 'axis', formatter: function (params) { params = params[0]; var date = new Date(params.name); return date.getDate() '/' (date.getMonth() 1) '/' date.getFullYear() ' ' date.getHours() ':' date.getMinutes() ':' date.getSeconds() ' : ' params.value[1]; }, axisPointer: { animation: false } }, ### What is expected? 能够按秒显示动态数据折线 ### What is actually happening? 每分钟的前10秒会卡住，然后不绘制这段时间内的折线 <!-- This issue is generated by echarts-issue-helper.
