How do I create a Gantt chart in Jira?

1. Install a Gantt app such as BigGantt from the Atlassian Marketplace. 2. Choose the projects or a filter to show on the chart. 3. Add dependencies as issue links and set milestones. The app draws the timeline from issue dates. In Easy8 the Gantt chart is built into every plan, so there is no app to install.
