We haven't encountered such an issue in our internal tests. I have prepared for you a small runnable demo application that shows live data coming every second and restricting the range to the last 10 seconds of data. Can you please check it in your environment and see if it is working as expected?
In the images you shared we can see that the horizontal axis has been reverted (showing the newest data to the left instead of to the right as normal). Can you confirm that this is a desired effect and how you are achieving it?
