研究方向

Examine the VChart source code, specifically the markArea label rendering logic (likely in packages/vchart/src/component/mark area/). Look for how dx and dy are currently used; they are likely numeric values. The task is to modify them to accept functions that return numbers. Check other similar properties in VChart that already support function types as a pattern. Since the issue has two assignees, check their progress and coordinate contributions.
