In Gantt chart, the bars represent three pieces of information: the beginning and end dates of a task as bar length and the task progress as bar color. Task progress is based on completion in percentage, not the status. The color meaning is hardcoded like this:
- blue - upcoming tasks, milestones, and completed tasks without completion ratio;
- green - completed tasks with completion ratio (%);
- red - overdue tasks with completion ratio (%);
- grey - a group of tasks.
For more details, please see the documentation: Create charts - eazyBI for Jira.
However, you may define a calculated measure to represent the task progress in percentage based on the status. For the calculation, use condition CAE WHEN … THEN. For example:
WHEN [Measures].[Issue status] MATCHES "Done|Closed" THEN 1
WHEN [Measures].[Issue status]="In Progress" THEN 0.5
WHEN [Measures].[Issue status]="Evaulating" THEN 0.25
WHEN [Measures].[Issue status] MATCHES "Backlog|Open" THEN 0
There are more details on how to use conditions for calculated measures: Calculated measures - eazyBI for Jira.
You may take a look at those two examples in the Demo account to get more ideas on how to represent Epics and their progress in the chart:
