Why isn't my Sprint burndown report burning down for team-managed projects?

[Henry Min]

I'm using a team-managed project and utilizing the sprint burndown report. However, I've noticed that the red line in the report only reflects the total story points remaining in the sprint and moves downward only when a story is moved to the "done" status. My workflow consists of a start-to-finish process with significant milestones in between. I'm wondering if there is a way to make the red line burn down based on the start-to-finish steps in my workflow, rather than solely relying on story points. Currently, my team doesn't revise story points on a daily basis. I appreciate any advice you can provide.
