Pie-chart drilldown for Stackalytics

When clicking on a segment in any of the pie-charts (for example, contribution by HP contributors at: http://stackalytics.com/?release=havana&metric=commits&project_type=All&module=rally), nothing happens – we need to select the various dropdowns to change the query parameters to adjust our query accordingly.

Proposal: When clicking on a segment in any of the pie-charts, the webpage should be able to automatically change the “query” and display the information accordingly

Example:

1: Before clicking pie-chart segment: http://i.imgur.com/LLO0ROU.png

2: After clicking pie-chart segment: http://i.imgur.com/hhhOsej.png (note that the query has changed)
