This extension has not been updated in over 2 years. It may no longer be maintained or supported and may have compatibility issues.
The plugin queries the SQL database created by the data plugin, aggregates data from a specified class of pages. The aggregation results are then output in the syntax needed by the c3chart plugin and, thus, visualized using that plugin (if available).
The plugin allows page visitors to select the aggregator and the grouping and change them.
The plugin comes without any warranty but I hope it is useful for other people. It needs certain sanity checks to be useful in public pages.
See the plugin in action here.
It allows users to change the aggregation and grouping of the SQL query.
