click property

Fires when clicking on the plot background. One parameter, event, is passed to the function, containing common event information.

Information on the clicked spot can be found through event.xAxis and event.yAxis, which are arrays containing the axes of each dimension and each axis' value at the clicked spot. The primary axes are event.xAxis[0] and event.yAxis[0]. Remember the unit of a datetime axis is milliseconds since 1970-01-01 00:00:00.
