I wish to label my geographic coordinates (DMS) on my graticule with only principal digits showing, except for the corner labels - much in the same way it can be done with MGRS grid.
How is this possible without:
using an XML in the 'Make Grids and Graticules Layer' tool or
converting the grid to a graphic and editing?
By Principal digits, do you mean no decimal places, only the degrees value, or something else altogether?
Hi Sephe, the Principal digits being the minutes value.
Unfortunately, I think you're right, and you can only do this with the methods you listed.
