I'm trying to build a Gantt chart from data received in the Jira Issue macro. I found that when inserting the Jira Issue macro there is an option stated "Other Jira Content" with a single option 'Jira Charts'. Clicking this brings up the standard JQL search to build a chart. Below the JQL search bar, there is a "Display Options" dropdown where the X-Axis and Y-Axis params get changed. One of the options for an axis is "Gantt Options". I can't find this documented anywhere and would like to know how it works.
