This is a long standing problem (for me anyway) - see thread from 2012 https://www.mail-archive.com/[email protected]/msg26480.html I still have the problem but have learned to adapt … I upgrade the csv output to the appropriate scales in GNU Octave and replot… bit of a pain but it works. Interesting that you are experiencing this on a Linux system - others reported the problem not replicated on Linux back in 2012.
