Re: Pan/Zoom and Screen Tap is broken on iOS.

Hi,
ok, thanks for all the information.
Not sure if the problem also happens by using the TeeChart for Xamarin.Forms 4.2020.5.28 version with an older version of Xamarin.Forms.
We're working on this and hope we can have a new maintenance release soon that fixes these problems.

Re: System.ArgumentNullException Value cannot be null. Parameter name: type

Yes, the exception seems to be related with Xamarin.Forms v5. Not sure if it also happens to you with older Xamarin.Forms version.

Re: Add scalable image to gauge chartview (Xamarin Forms)

Hello, We successfully tested a startup, once-only timer that loads the image everytime on startup but we have found in tests, as you noted, that the image can disappear unexpectedly at some screen paints. We think this is down to the environment and are following up on it. In the meantime we offer ...

Re: Add scalable image to gauge chartview (Xamarin Forms)

Hello,
sure, let me check the example you've attached and back to you asap.
Most likely it can be solved by calling to the draw method at the OnBeforeDrawSeries event, but let me check and see what happens.
