Issue filtering Edit
To update the starting set of issues displayed in the diagram, type the filtering query in the filter panel at the top of window. The filtering query must be written using JQL syntax.
The set of selected issues constitutes the starting point to draw the graph. The diagram will actually show these issues plus their connected issues. Which connected issues will be added is determined by the Issue filter selection.
JQL queries Edit
The starting set of issues used for the diagram is selected using a JQL query. JQL is a simple yet powerful query syntax defined by JIRA for selecting issues. For all details on JQL and more examples, please refer to JIRA's documentation on Advanced searching.
