Scrum burndown with support for re-estimates


A plugin to enable burndown chart capabilities (using Adobe Flash), a common part of Scrum and other agile development methodologies.

This plugin requires TimingAndEstimationPlugin and Free FusionCharts and was developed and tested on Trac 0.10.x.

I have used the existing ScrumBurndownPlugin as a model to develop a version including support for re-estimates which we needed. As far as the license info is concerned all of it should be completely free licensing. Please check with .

Download the zipped source from [download:burndownplugin here].


You can check out BurndownPlugin from here using Subversion, or browse the source with Trac.


You can view different burndown charts, selectable by milestone by choosing from the dropdown and clicking the 'Show Burndown Chart' button.

At the beginning of a milestone (i.e. sprint), make sure the tickets have been inputted and estimated in Trac. The 'Hours to Add' earliest entered determine the start of the milestone (i.e. sprint) while the one entered last define the end of the milestone.

In order for this to work, it is imperative that developers keep the 'Estimated Hours' and 'Total Hours' fields accurate and up-to-date on the tickets they are working. The 'Total Hours' field itself should never be manually edited, but rather, it can be changed by inputting positive and negative values into the 'Hours to Add' field.

During the spring you can entered revised estimates. The chart display 2 bars per day : one for the total amount of work estimated including revised estimates and a second one displaying the total amount of work performed. Like this you can also see how the total amount of work estimated evolves during the sprint
