Using the Maplex Label Engine to align horizontal labels to a graticule rotates all horizontal labels for a particular label class to a tangential line along the graticule for the data frame. To have your labels align with the graticule lines, the data frame must be set to a projected coordinate system. There are four graticule alignment types to choose from:
- Straight (no flip)
- Curved (no flip)
The Straight and Curved options place the label in alignment with the graticule and orient it to the page. The Straight (no flip) and Curved (no flip) options allow the label to be drawn upside down to align with the graticule.
The following image shows point labels oriented to graticules.
