This appears to be an issue with John's axis limit code he introduced
just before 2.9.18.. I'm not quite sure he was trying to achieve in the
graphics.cc(check_limit_val), as it manipulates the max, min and min_pos
values three times. I don't see why these tests shouldn't be completely
separate and propose the attached patch that fixes this issue for me.
However, John should validate it as only he knows what he was trying to
achieve in graphics.cc(check_limit_val).
