Hi,
Welcome to eazyBI community.
Note that eazyBI (on a new account) creates members in “Time” dimension automatically based on different issue timestamps. If none of the Issue fields are associated with future dates, these dates will not be created automatically in “Time” dimension which limits the future periods in your report.
In this case, you could try adding future dates to “Time” dimension manually.

That should add also future weeks and then chart would be extended
