We use JIRA Cloud and have a lot of parallel projects with even more tasks inside. For estimating the work load on the next four months, we would like to see a gantt chart with only projects, not tasks. So every project has a starting date and end date and the gantt chart only shows this data.
I only found solutions for displaying a gantt chart with the tasks of a project, but not an overview chart without the tasks. BIGGANTT e.g. renders all tasks and needs only for displaying this huge chart about 3 minutes - the result is so big, I can't see anything in it, it's just a mess.
Does a solution exist for this requirement?
