The Azure DevOps documentation that describes Burndown and Burnup Charts describes the following types of burndown charts (quotations are from the link above):
- "A sprint burndown tracks the sprint backlog completion by end of the sprint"
- "A release burndown tracks the release backlog completion by the end of the release"
- "A bug burndown chart to track the completion of a set of bugs by a certain date"
However, I would like to implement a feature burndown where the X-axis is a sprint or date (same as either of the 2 charts above) and the y-axis is either the count of the number of stories + bugs or the sum of the points. Most importantly, this feature burndown chart would show only the children of a specific feature item, such as this list of 4:
How can I please generate this feature burndown chart described above?
