Panning changes unintentionally when pinching the graph (zooming out)

[Dan Bar-Yaakov]

Hi

I have an annoying UI issue when pinching the SfCartesianChart to zoom out (pinch in to expand the X axis range). I'm using a DateTime axis. When I pinch in, sometimes the chart pans to the right. It seems like the chart first pans right to the location of the right finger and only then zooms out in response to the pinch in. Happens in iOS devices as well as the simulator. Take a look at the attached video please, the first pinch worked as expected (chart remained in the same position but zoomed out), the second pinch is where you see the chart rapidly moving to the right and then zooming. This happens every other pinch operation and is very annoying for users.

Has someone come across this as well and found some solution?

Thanks,

Dan

Hi

Thank you for the quick response. I'm glad this feature will probably be available in an upcoming release. Do you happen to have a link you can share with me so I can be notified when this feature is available? perhaps from your issue tracking system, if it's at all public.

Thanks,

Dan
