The SAFe Epic Dashboard does not show any data on sections Epic Burnup and Epic Cumulative Flow Diagram
There may be several reason why no data is showed on this sections:
Check the dates and the date format on your instance.
Check that the schedule job “[Scrum] Daily Data Collection” is active and running and the collections is finished without errors.
The field Run as is not defined out of the box so make sure you define it before executing the job.
Finally, make sure you have scores by checking the analytics hub of your indicators.
The epic burnup widget reads from the indicator "Scrum: Sum of story points of all stories in epics" and "Scrum: Sum of story points of completed stories in epics".
The Epic Cumulative Flow Diagram reads from the incidator "Scrum: Count of all stories in current epic"
