I cannot experiment by myself today, but here is my guess:
The MAP function already creates an object grid. The LABEL_POSITION=0
puts it "outside". You can suppress it by doing LABEL_SHOW=0 and,
likely, you can adjust it (step, labels, etc...) by using (poorly
documented) keywords... You added to my code a MAPGRID call, producing
the additional grid with default properties ("inside" labels, etc...);
I think that you can merely suppress it.
