### Version 5.4.0 ### Link to Minimal Reproduction _No response_ ### Steps to Reproduce online example: [example](https://echarts.apache.org/examples/zh/editor.html?c=line-smooth&version=5.4.0) Copy and paste the following code: `option = { animation: false, color: ['#445AF7', '#00B42A', '#FF7D00', 'rgba(29, 33, 41, 0.65)', '#F53F3F', '#849AFA', '#95E89D', '#FFDCA3', 'rgba(29, 33, 41, 0.25)', '#FFE9E6'], tooltip:{"trigger":"axis","enterable":false,"confine":true}, grid:{"left":"0%","right":"2%","bottom":"1%","containLabel":true}, legend:{"type":"scroll","top":"5px","left":"0%","width":"50%","itemWidth":15,"itemHeight":10,"tooltip":{"show":true},"data":[]}, xAxis: { type: 'category', data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'] }, yAxis: { type: 'value' }, showSymbol: false, series:mockList(2000) }; function _randomNumber(n, m) { return (Math.random() * (n - m) + m).toFixed(2) } function _mockItem(){ const data = []; for (let j = 0; j < 7; j++) { data.push(_randomNumber(1, 100)) } return data; } function mockList(num){ const res = []; for(let i=0;i< num;i++){ res.push({ data: _mockItem(), type: 'line', sampling: "average", symbol: "none", showSymbol: false, smooth: false }) } return res; }` ### Current Behavior There are 400 lines, each line has about 1000 points, rendering is stuck, how to optimize ### Expected Behavior Expect to provide specific solutions for optimizing rendering performance ### Environment ```markdown - OS: windows 10 - Browser:chrome - Framework: ``` ### Any additional comments? coding -- This is an automated message from the Apache Git Service.
