pyGMT gridlines going over lat, long labels

Q&A PyGMT Q&A

I’ve got a simple map with some custom gridlines. The gridlines go through the latitude and longitude labels. However, the lines go through the text. How can I adjust the labels to move lat slightly above the line and lon slightly next to the line. The config offsets in docs don’t seem to do that.

with pygmt.config(FONT=f"{size_scale*2}p,{FONT}",     MAP_FRAME_TYPE="inside", MAP_GRID_PEN_PRIMARY="0.1p,black"):
    fig.basemap( 
        # justify='bl',
        region=region_map,
        projection="M12c",  # Mercator projection with a width of 12 centimeters
        frame=["af+s25p/25p/gray30", 'x1g1', 'y1g1']
    )

From what I understand one cannot just configure tick labels the way you want it.

You could however instead use custom tick/label mechanism of GMT. You’d need to create a custom annotation file per axis and separately indicate annotation labels with an offset and gridlines at the exact positions, like

...
# gridline at an exact position:
23.0 g
# annotation with a suitable offset
23.1 a 23°00'N
#  you'd have to manually format annotations with the degree char and the hemisphere char
# this may be another quest
...
