Is it possible to determine, which part of stacked bar was clicked (ie, know the trace for the that part)?

For example, in this [example](http://codepen.io/eagor/pen/VKpajj) how do I know if LA or SF Zoo was clicked? The plotly\_click handler passes all traces under .points property, without obvious hint to the one was clicked.

Or is there a way to get the click coordinates, so that I could use axis scales to calculate the trace that is positioned there?
