Sorry I was a bit unclear - the callbacks are not currently available, but will be in V1.2. As it turns out, Selection is the feature I have assigned to myself for this release, and the notification element of it is not yet started - I’m currently working on the actual behaviour in response to gestures. When I do get onto the notification part, I will be implementing it using a pattern very similar to the way pan/zoom/axis notifications are handled, with a listener interface to notifiy you of the gestures themselves, and separate listener interfaces to notify you of the changes that occur in the chart as a result of the gestures.
Having said that, i’m also confident that those expectations will be confounded - it’s alway interesting and surprising to find out what people actually do with our charts! In your snippet above you’re listening to everything, which is only necessary if you’re actully going to do something as a result of each callback. You’re not finding onClick because we have no use for it in the context of pan and zoom - that’s all swipe and fling - but we will have some equivalent in when Selection is done.
