In my company we are trying to use EstimationToolsPlugin - it's working, but we would like to have the possibility to diferenciate tickets by ticket_type attribute.
We have a specific type of ticket that represents unplanned activities, and I would like to represent them on another line, just like the following image:
One way to represent that would be adding an attribute line_attribute to the burndown line setup:
[[BurndownChart(milestone=Sprint 045, startdate=2009-11-01, enddate=2009-11-13,
Hope that u consider this feature request.
