[GRASS-user] geogrid not smooth in ps.map output

[Tyler Smith]

Hi,

I'm making a map for inclusion in a manuscript. I have the basic layout
set, using the wx display system: https://flic.kr/p/CThHdE

Not perfect, but I can tweak the placement of labels in Inkscape.
However, when I try to transfer the code from d.mon to ps.map, the
gridlines become 'jointed', rather than smooth curves:
https://flic.kr/p/DEp7zL

I've tried setting the region resolution, but it doesn't seem to change
anything. How can I plot geographic grids as smooth curves with ps.map?
Or is there a better workflow to accomplish this?

Best,

Tyler
