HYT0110 opened a new issue, #21414: URL: https://github.com/apache/echarts/issues/21414
### Version 5.4.2 ### Link to Minimal Reproduction Please refer to the images in the description. ### Steps to Reproduce I am using ECharts echarts.connect() to link tooltip and axisPointer interactions across four charts (Chart 1, Chart 2, Chart 3, and Chart 4). All charts share the same timestamp-based x-axis data, and all charts are assigned to the same group. In general, the connected charts work as expected. However, there is a consistent issue where the last data point on Chart 3 or Chart 4 does not link to Chart 1 and Chart 2. <img width="888" height="225" alt="Image" src="https://github.com/user-attachments/assets/673a35fd-812a-48bb-bf23-f641d54cd781"; /> ### Current Behavior **Observed Behavior** Chart 1/2 → Chart 3/4: the last data point links correctly <img width="886" height="227" alt="Image" src="https://github.com/user-attachments/assets/f999bc39-f0c7-4979-86fb-468d9d334e87"; /> Chart 3/4 → Chart 1/2: the last data point does NOT link <img width="892" height="225" alt="Image" src="https://github.com/user-attachments/assets/ee31abad-8404-4555-bb1e-873590b28876"; /> All other data points link normally This behavior occurs only on the last data point and only for specific charts (typically Chart 3 or Chart 4). **Additional Details** <img width="889" height="224" alt="Image" src="https://github.com/user-attachments/assets/05ceabcf-ac67-4e48-8880-57f8fd57b4c2"; /> After using dataZoom: The second-to-last data point still links correctly When this point becomes the last visible point, the linking issue appears again Does this suggest that the issue is related to the final axis position or x-axis boundary behavior? I have also tried adjusting the grid size, but the same problem still occurs. ### Expected Behavior When hovering the last data point on any chart in the group, all charts should show the corresponding tooltip/axisPointer through the connect() mechanism. ### Environment ```markdown - OS: - Browser: - Framework: ``` ### Any additional comments? _No response_ -- This is an automated message from the Apache Git Service.
