### Description When clicking on a task in the grid view, a newly-created chart that shows the duration of the tasks shows two reference lines. It is not clear what these reference lines mean and there should be a legend that describes what they are. Is one the average duration and the other the median duration? ![image](https://github.com/apache/airflow/assets/421551/9523247f-dd4c-423f-8abd-0a724d0e096c) I think it would make sense to have a legend either below or beside the graph to describe what the reference lines are. ### Use case/motivation The motivation is to allow users to understand what the lines on the chart represent. ### Related issues _No response_ ### Are you willing to submit a PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
