I need help in a creating a burn down chart for a set of EPICs/Stories that are required to finish at code freeze milestone. I do not want to use release burn down canned report from JIRA as it brings all stories and EPICs for other teams too. I need to only look at burndown chart sprint over sprint for set of stories that are planned for my project and are planned to finish by a certain code freeze date. This code freeze date is not in any JIRA field.
Can someone please help with that ?
