I agree this is surprising, that it appears so consistently and
wasn't previously reported. The line across from the lowest tic
mark seems to always be missing if the lower Y limit does not
coincide with a tic mark. I think this will be an easy thing to
fix in the code.
Ryo, I think that if you add a line using PLOT/DASH=(0.03,0.05,0.03,0.05), that it would match the graticule lines.

Dear Ferret users,
I'd be surprised if this weren't a known issue, but I haven't found a description of it in the email archive.
The code at the end of this message generates the plot below. As you can see, the graticule line is missing at 15°S.
I could just add the missing line, but I don't know what dash type graticule uses. (plot/dash . . . plots a totally different long-dashed line.)
