This was fixed recently for 2.8. Do you have any chance to try out the current development version for 2.8 (https://labplot.kde.org/download/) and check the behavior?

It works!
I installed the development version (2.7.0 + git202006101003 ~ ubuntu20.04.1) from the repository ppa:rikmills/experimental, as you suggested. This problem does not occur there.
Thank you very much for help.
