In case you have geographical information in your input data file, you can superimpose on the plot geographical coordinates either as map projection coordinates or as latitudes and longitudes. Furthermore, you have the opportunity to add plotting symbols indicating true north and the convergence, defining the angle between the longitude and the northing line for the map projection. The indications of true north and convergence can be moved later, directly on the picture, using the Popup Menu.
When you are superimposing a coordinate system, the one specified in the "Map projection type" box will be used. The default Map projection is the one specified in your background input data file.
If you select Northing coordinates always positive, the northing coordinates will be as 1) and 3) in Figure 6.2. If you don't select it, the southern hemisphere northing coordinates will be as 2).

Finally, you can specify additional axis annotation.
