[Q] Story Point Remaining excludes stories with links

The existing "Story Points Remaining" Graph (story point burndown graph for the iteration), does not accurately reflect the story points remaining. It doesn't show completed stories if any of the completed stories have links to other stories that are not completed. (an associated link).

Is there a way to get a chart that just shows total story points in the current iteration against the burnup of completed stories in the current iteration regardless of whether they have links to other work items associated to them?

Thanks, Dmitry
