URL: https://github.com/apache/superset/pull/34759#issuecomment-3938758600
## **Sequence Diagram**
The PR changes the ECharts tooltip formatter to prefer
axisValue/axisValueLabel (full category labels) when available, falling back to
the original value extraction. The diagram shows the core hover → formatter →
tooltip text flow that this PR modifies.
