Issue details graph allows to filter displayed issues. There are four available filters:
- Link type (1)
- Issue type (2)
- Issue status (3)
- Priority (4)
Only issues that match selected criteria are displayed. Criteria are defined by selecting proper options from filters' drop down menu. For issue to be displayed, it has to match one option from each active filter.
There might be a situation when an issue that matches all criteria is hidden. It is because the issue has no connection to a root issue due to another one that doesn't match criteria.
