Pull to refresh

[a5544321]

Hello,is there any property or protocol to tell if I drag the chartView to the end of left or right?
I want to do something like "pull to refresh"
I found there is a OnFling listener in Android version document,but I can't find in ios charts
Can anyone help? Thanks

The onFling is something that comes by default when you implement the basic Gesture recognizer on Android.
On iOS we do not have to have that overhead by default - and if you want to have a swipe gesture recognized, just add a recognizer. You do not have to modify any of the Charts code - just add a recognizer to its gestureRecognizers array.

Thank you for your answer.But my problem is sometimes I will zoomIn the chart and swipe it left and right
but I only want to do something only when I scroll to the end . Is that doable?
And after I try to add a swipeRecognizer on chartView .It didn't work only if I swipe very very very fast.
Thank you.

Swipe gesture is a fast gesture, but you probably can change its
configuration.
If you received the delegate's messages you can know whenever the position
has changed, and compare it with the viewport.

Sorry , is your delegate means chartView delegate? I only can find chartvalue select and unselect in it. And I don't know what your position mean. Is viewport means viewportHandler? What property in it I should compare with position? Thanks..

You need to pull the latest version.
