Starter blurb for docs
A burndown chart is available for every project milestone that has a set start date and a set due date. It is located on the project milestone page. It indicates project progress throughout that milestone (for issues that have that milestone assigned to it). In particular, it shows how many issues were or are still open for a given day in the milestone period. Since GitLab only tracks when an issue was last closed (and not its fully history) the chart assumes that issue was open on days prior to that date. The burndown chart can also be toggled to display the cumulative open issue weight for a given day. When using this feature, make sure your weights have been properly assigned, since an open issue with no weight would contribute zero to the cumulative value.
