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.
