It can be done in QGIS, but how to do that in Mapinfo?. I need to classify the labels color by attributes from a column.
Hmmm not easily! and not without MapBasic or a lot of work to the best of my knowledge.
How many attribute types do you have? If there are only a few you could query each attribute, add the result to the map, and style the labels accordingly.
Aside from that the only other way that I thought of would be to effectively do the same thing, but use MapBasic and loop through each of the attributes, add it to the map, style it and move to the next one.
