Before getting to your questions I would like to ask you which product are you using as this doesn't seem to be native iOS?
Are you using NativeScript with NativeScript UI?
If yes, please make sure to post questions related to NativeScript UI to the corresponding forums as these here are dedicated to UI for iOS.
Back to your inquiry:
This is a known issue with Chart for iOS and we have logged it on our TODO list for fixing. The userInteractionEnabled property works as a workaround - we have tested this on our side - so you might not be setting it properly.
Can you share some more code or a project that we can inspect for better understanding?
