When legends contain many items, they can grow beyond the available container space and overlap with the main chart area (grid, radar, etc.). The current behavior calculates `maxHeight` as `containerHeight - bottom - verticalMargin - top`, but doesn't enforce any upper limit when users specify a height constraint. <img width="538" alt="image" src="https://github.com/user-attachments/assets/6f2cb8b3-fd52-4a8a-b70d-5cd1c3f881cc"; /> ### After: How does it behave after the fixing? When `legend.height` is specified, the legend will automatically scale down if its natural height exceeds the specified threshold. <img width="539" alt="auto scale" src="https://github.com/user-attachments/assets/b2373741-1cf2-46d3-afd2-2552b9796ccd"; /> <img width="535" alt="image" src="https://github.com/user-attachments/assets/ea90c08c-782f-4ead-a15a-4aea82b85f22"; /> ## Document Info One of the following should be checked. - [ ] This PR doesn't relate to document changes - [x] The document should be updated later - [ ] The document changes have been made in apache/echarts-doc#xxx ## Misc ### ZRender Changes - [ ] This PR depends on ZRender changes (ecomfe/zrender#xxx). ### Related test cases or examples to use the new APIs Test file created: test/legend-height-formats.html ## Others ### Merging options - [ ] Please squash the commits into a single one when merging. ### Other information I'm not sure if this is the best approach to solve this problem, and I'm happy to iterate and improve based on your feedback and suggestions.
