My proposed fix would be the alter the unit formatting if two or more on-screen markings are identical. There may be some trickiness in ensuring that the markers don't overlap one another.

研究方向
Investigate the rendering code for unit markers, likely in the zoom logic and time axis formatting. Look for files handling canvas or SVG drawing of markers, and understand how precision is determined. Check the repository's source for any existing tests or comments about marker overlap.
