Unsupported Theme Expressions
Some theme expressions used in MapInfo Pro are not supported by Spectrum Spatial. When a map is created in Spectrum Spatial using a non-supported theme expression from MapInfo Pro that theme will not be displayed in the map. The layer with the theme will be displayed as if it did not have a theme. Some expressions available in MapInfo Pro are not supported in Spectrum Spatial, including ObjectGeography (object, attribute), ObjectInfo (object, attribute), Maximum ( num_expr, num_expr), Str$ ( expression), and Val ( string_expr).
Thematic maps with half-pie charts are also not supported at this time.
