Lack of clarity in the visualization of VSA "Stage time" metrics (Adding median to the chart)
Problem to solve
Users of VSA are frequently confused about what VSA stage time chart is displaying.
Dogfooding feedback:

The reason is that, the "stage time" shows the median
of all issues in this timeframe, however the "Stage time chart" displays the average
. Also the chart tooltip don't display the value type (mins or days).

- Erin (Application Development Executive)
- Parker (Product Manager)
Proposal
- Adding the the total median time to the chart. (Example).
- Add the median time also to the chart tooltip.
User experience goal
Getting immediate insights about what what's happening in the specific stage by visualizing the performance of the stage.
Additional information
- Medians were chosen for VSA because they exclude "outliers" - extremely high or low values that skew averages.
