For a Sprint Burndown Chart, the x-axis is usually the days inside the sprint.
Sprint burndown
| Axis | Meaning |
|---|---|
| X-axis | Days of the sprint |
| Y-axis | Remaining work |
Example:
| Day | Remaining work |
|---|---|
| Day 1 | 100 points |
| Day 2 | 85 points |
| Day 3 | 70 points |
| Day 4 | 50 points |
| Day 5 | 25 points |
| Day 6 | 0 points |
So for a 2-week sprint, the x-axis may show:
Day 1, Day 2, Day 3 … Day 10
or actual dates:
July 1, July 2, July 3 … July 14
When would x-axis be “sprints”?
That is usually for a release burndown or product/release tracking, not a sprint burndown.
| Chart type | X-axis |
|---|---|
| Sprint burndown | Days within one sprint |
| Release burndown | Sprints or iterations |
| Product burndown | Sprints, releases, or time periods |
Teaching line
Sprint burndown tracks daily progress inside one sprint. Therefore, the x-axis is normally days or dates, and the y-axis is remaining work.
So the answer is:
For sprint burndown, use day/date on the x-axis.
For release burndown, use sprints/iterations on the x-axis.
