I have had luck placing a transparent DIV over the annotated time line to catch clicks. You can query the current displayed range to figure out the time where the user clicked, update the DataTable and then re-draw, or in my case I used it to display some additional information associated with that point in time.
This is first degree hackery, but it let me prototype some ideas pretty quickly. I am not sure I'd recommend it for production use just in case something changes in Viz. -Bill On Mon, Oct 10, 2011 at 12:04 PM, Jinji <[email protected]> wrote: > If you need something that allows the user to click on any point on the > chart, and add an annotation in the point, then this is not supported, > sorry. > > > On Sun, Oct 9, 2011 at 12:02 PM, Eran <[email protected]> wrote: > >> Hello, >> >> I'm looking for a chart similar to Google Annotated Timeline, that >> allows online additions of new tags by the user - and throws an event >> each time a new tag is added. >> >> The events in the Annotated Timeline only allow for firing and event >> when an existing Marker is clicked.
