Use Case: Building an Extended Profiler with mongod log data.

The right-click event maybe satisfactory if it is added to the expanded view, and the scatter plot point is anchored so that after you are done with the data view pop-up, you can quickly see what point you clicked.

The other option, possibly better is to expose the click-event that is already there in the SDK but make it available in the Atlas Charts UI. A couple common actions could be keeping/expanding the tooltip onClick, or open another window that is tethered to a field or the entire documents data, again anchoring the position you clicked so you don't lose your place.
