I'm developing a Gantt Chart in Confluence, based on project plans, dates, etc. I'd like to include real-time JIRA data as well. I know how to display a JIRA chart in Confluence, but instead I just want to pull out "percent-complete" out of a JIRA project (based on number of issues completed vs remaining, or maybe story-points completed vs. the total in the sprint). Is there anyway to query a "number" like this from JIRA, which would then show up in a cell in my table and be rendered into the Gantt chart?
