Easy chart interpolates to zero forever

[WhatsApp Image 2020-06-16 at 10.09.10] I am using ignition 8.05 and we have a easy chart component that is showing presssure values. When a manual valve is shut the ready of the pressure transmitter is zero. the question is why is the easy chart showing an interpolation from the last value to zero rather then having a constant zero line?

Some advice in this thread, might help
