I understand that charts and reports generally work off searchers (code that tells Jira how to index and search a field) and not a field. However, I have a circumstance where I would like to use a range for a pie chart. I am helping teams move to an agile methodology and replace Severity/Priority with Business Value (0-99). As such, I would like my pie chart to display ranges such that it can display x=99 (showstoppers), 99<x<=90 (all critical issues) etc.
