### Version 5.4.3 ### Link to Minimal Reproduction https://jsfiddle.net/plainheart/xxx ### Steps to Reproduce null ### Current Behavior https://github.com/apache/echarts/assets/9067839/94b9b15d-9595-4fa0-999c-f0895c7cda04 The init echarts config: ```ts export const initEchartsOption: EChartsOption = { xAxis: { show: false, }, yAxis: { show: false, }, series: { type: "line", showSymbol: false, smooth: true, data: [], lineStyle: { color: "#000", width: 3, }, sampling: "none", }, grid: { right: 0, top: 20, bottom: 20, left: 0, }, animationDuration: 0, animationDurationUpdate: 500, animationEasing: "linear", animationEasingUpdate: "linear", }; ``` and evert 500ms I will set new options: ```ts chartRef.current!.setOption<EChartsOption>({ yAxis: { min: renderData?.minYAxis || 0, max: renderData?.maxYAxis || 1, }, xAxis: { min: latestData.timestamp - liveLineHistoriesConfig.time_offset, max: latestData.timestamp, }, series: { data: newData, }, grid: { right: 100 }, }); ``` As can be seen, when a new point appears on the right, there are two issues: 1. The line is drawn from thick to thin. <img width="174" alt="image" src="https://github.com/apache/echarts/assets/9067839/f9880f11-2bfb-4cbe-8b0c-bc4bdafd99b4";> 2. After the line is drawn, it jitters and changes into a smooth curve. ### Expected Behavior looks ok ### Environment ```markdown every ``` ### Any additional comments? null -- This is an automated message from the Apache Git Service.
