Chart.js prototype functions not implemented

[jordan-wester]

The documentation for Chart.js states that there is a prototype method, getBarsAtEvent(e), that is available to determine which bar in the chart was clicked on. I don't see anything in the angles.js script that implements any of the prototype functions or an alternate method of capturing click events.
