Initial configuration

Having logged in as JIRA system administrator and having downloaded, installed the Gantt-Chart add-on and get a license key via the Atlassian Marketplace, you have to configure it once: please click on the configure-button within the expanded Gantt-Chart section of the "universal plugin manager" (UPM) inside JIRA administration, modify the settings according to your local needs or take over the defaults and in both cases, click on the apply/finish button at the bottom (without clicking on apply, nothing will be changed within the local JIRA nor any default settings are stored/taken over):

Please create a new filter e.g. named "Epics" using the following JQL as template: modify the project key and use the names for the fields "epic name" and "planned start" according to your local configuration, language and need. Then share this filter to all related users.

project = 'my Project' ORDER BY 'Epic Name', 'Planned Start', issuekey

Within the selection box, users can choose that filter an get a special view as displayed below: epics are used as grouping element now. If you enable option "multi-projects" within the Gantt menu (small gear on the right top within the diagram), you will get a pretty overview on a high level.
