Render burndown images in svg format

Notice: This plugin is unmaintained and available for adoption.


This plugin creates customizable burndown graphs from the ticket history provided by TimingAndEstimationPlugin. Dynamic graphs can be easily embedded into Trac wiki pages.

To test graphs and filtering, access your project environment, such as the following: http://server:port/path/to/trac/env/tractimevisualizer. It will render the hours from the whole project's life cycle and display the graph in svg format.

More practical is to get graphs from a certain time frame and filter the hours based on milestone and/or component. This is achieved with macro BurnDown. This plugin replaces ScrumBurndownPlugin, because its graphing capabilities are limited and it modifies the database schema.

In my example project, I have a wiki page with following content:



It renders the following graphs (picture is cropped to fit better on this page):

Note that different colors can be specified:

For more information, see browser:/timevisualizerplugin/branches/TimeVisualizer_0.6/release_notes.txt

Developed and tested with Trac 0.10.4, Python 2.4, sqlite, mod_python and Apache on Windows. The 0.6 version of this plugin works on Trac 0.11.

Feel free to give feedback.
