Render burndown images in svg format

Links: open tickets | new ticket | svn | browse code


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

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

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


Dependencies: TimingAndEstimationPlugin was needed in 0.4 and earlier versions to feed the database with estimates and totalhours custom tickets. Browser must be able render SVG natively and support the html tag iframe. The latest Firefox, Opera and Safari browser versions should work.

  1. Get source files and install it:
    svn co
    cd TimeVisualizer_0.6
    python install
  2. Edit your trac.ini file to enable the plugin:
    <...other components...>
    tractimevisualizerplugin.* = enabled
  3. Restart server to propagate changes.

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


To test graphs and filtering, access "http://server:port/path_to_trac_env/tractimevisualizer". It will render the hours from the whole project's life cycle.

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. I wrote this plugin to replace ScrumBurndownPlugin, because its graphing capabilities were 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):
