JavaScript Chart click event

This event is raised when the user clicks on the chart.
A single argument is passed to the function. Given that this single argument is called "args"
in the handler, like this:

events: {
    click: function(args) {
        // handle the event
    }
}

It gives access to the following properties:

args.domEvent.originalEvent
args.domEvent.type
args.domEvent.isDefaultPrevented
args.domEvent.timeStamp
args.domEvent.isPropagationStopped
args.domEvent.isImmediatePropagationStopped
args.domEvent.preventDefault
args.domEvent.stopPropagation
args.domEvent.stopImmediatePropagation
