Callouts are placed in any of the following eight positions:
By default, the placement order starts at position one (1) and goes in a clockwise order through to position eight (8). You can change the starting position by modifying the Label Position located in the Label Placement section of the Labeling Rules properties, placement then continues clockwise until a position is found or all positions have been tried.
The center label position is the same as top-right or position one (1).
MapInfo Pro places a callout label for a region outside of the region's bounding box. If a region has a thin and jagged shape, such as a region representing a river, then its callout label might be located at a considerable distance from the region. If the callout line is too long, then drag the label closer to its region.
