URL: https://github.com/apache/superset/pull/38657#issuecomment-4063291916
## **Sequence Diagram**
This PR updates the time series chart option builder to compute the data
zoom slider bottom offset from chart height instead of always using a fixed
value. The result is that zoom controls stay visible in shorter chart panels
while preserving the previous minimum spacing.
