@Yurunsoft It seems you are not using English, I've helped translate the content automatically. To make your issue understood by more people and get helped, we'd like to suggest using English next time. 🤗 <details><summary><b>TRANSLATED</b></summary><br> **TITLE** [Feature] Some suggestions for preserving sampling details **BODY** ### What problem does this feature solve? We have 2 demand scenarios: 1. 16 temperature curves are rendered in a separate dom. Each curve may have up to 30,000 points, and the data is refreshed every 1s. 2. 3 curves are rendered in separate dom, 2 of which may have up to 30,000 points, and the third curve may have up to 60,000 points, and the data is refreshed every 500ms. Scenario 1 requires that details are not lost as much as possible and is sensitive to high and low temperature locations. Currently, the new minmax algorithm of 5.6.0-rc.1 is used, and the amplification may be different from that without sampling. Scenario 2 uses the new minmax algorithm of 5.6.0-rc.1 to basically meet the needs. It is recommended that after you turn on sampling, if you zoom in and the number of points in the zoomed display area <= the maximum number of points that can be rendered, use the original data for rendering. Or you can dynamically sample according to the zoom factor, which can better preserve details. ### What does the proposed API look like? No changes to the API or adding configurable items. </details> -- This is an automated message from the Apache Git Service.
