Timeline question - accessing visible start/end date

I am using the latest version of the Timeline object. I can adjust the slider to zoom in/out across the data, but I would like to be able to access the current values of the displayed start/stop times showing in the graph, and I don’t see any way to do that. There is a selectedStartDate and selectedStop date field which are displayed at the top of the graph, but I don’t see how to pick up those values.
Am I missing something simple? Is there something I can do to get those 2 values?



You can attach a
to the Timeline which will receive a
with the values you want. The event is triggered whenever the selection in the Timeline changes.

I see - thanks John
