After writing down my latest ideas for better Piwik visualizations, I just couldn’t wait to see them in action. Since the Open Flash Chart library doesn’t support multi-level pie charts I decided to create the visualization from scratch. The initial version (0.1) took me about two hours coding.
In the following image you can compare the hierarchical pie visualization (top) with the current pie visualization (bottom).

I named the plugin UserSettingsExt as it extends the current UserSettings plugin. You can download it from the Piwik Developer Zone to test it on your own Piwik installation.
Changelog
- 0.1 – basic pie chart drawing, label placement.
- 0.2 – added standard piwik tooltips
- 0.3 – added automatic resizing
If you don’t want to miss any updates, you can subscribe to the plugins rss-feed at the Piwik Developer Zone.
Feedback welcome.
