How do I add crosshairs to a Line chart?

I have a Line chart that I'd like to add crosshairs when the user clicks or hovers over a point.

The easiest way is to just use the crosshairs* properties. With the Line chart it only works with the mousemove event.

I've made you an example and it's here:


Initially I said that you had to use the Scatter chart for this - but that is only if you wish to get an X/Y coordinate pair (since the Scatter chart has an X axis scale). This example shows a Line chart with crosshairs.
