New worksheet, fill xyyy with random data, plot vertical drop line
Open Plot Details dialog, go to Stack tab, set stack to auto, select custom additional line by relative position, ok
Open axis dialog--> note Y from -0.1.
Go to grid tab of vertical, set Y=-0.2 for additional line, ok. drop line drop to relative position
==> But additional lines for relative position do not show. If we set Y from -0.2, then lines will show. We should show relative additional line in such case if the relative position is within scale range. This issue exists when we not show additional line outside of axis range from Origin 2022b
