akloeckner opened a new issue, #21532: URL: https://github.com/apache/echarts/issues/21532
### Version current ### Link to Minimal Reproduction see below ### Steps to Reproduce Use the ECharts help here: https://apache.github.io/echarts-handbook/en/how-to/chart-types/line/basic-line/ Select a few points and set smoothMonotone to `x`. With `smoothMonotone`: <img width="1080" height="1693" alt="Image" src="https://github.com/user-attachments/assets/b6e0e493-9fb6-4bb7-b2e4-d2c47e4804aa"; /> Without `smoothMonotone`: <img width="1079" height="1691" alt="Image" src="https://github.com/user-attachments/assets/633dd306-f478-40d9-b57d-9227e6eb9428"; /> ### Current Behavior Setting the option generates saddle points at the actual data points. ### Expected Behavior The graph should not have saddle points but simply be monotone. ### Environment ```markdown ECharts help ``` ### Any additional comments? I found this when examining data shown in home assistant. The data was surprising to me until I realized it was actually a graphing artifact.
