Labeling Your Map
Labeling with a Column
The content of labels is controlled in the Label with drop-down list in the Label Options dialog box.
You can label an object with any column from its associated table. For example, you can label the
STATES table with the state name, abbreviation, 1990 population, or any other field in the STATES
table. Simply choose a column from the list, and the objects in that layer will be labeled with the
information contained in that column.
L
You can only set a Label with expression on a single layer. After selecting multiple layers in
the Layer list, the Label with list disables and shows a message that says Mixed.
Labeling with Expressions
You can also label objects with an expression. Select Expression from the drop-down list in the
Label Options dialog box. Create the expression in the Expression dialog box. You can type the
expression directly or use the drop-down lists to create it. For example, you want to label the
countries of Africa with their name and population density on two lines. Your table contains the
country names and population figures for each country. To figure the population density, divide
population by each country’s area. You can let MapInfo Professional calculate the area of each
country using the Area function in the Expression dialog box. To create the expression, in Layer
Control, double-click the Africa layer and click the Label Display tab. Select Expression from the
Label with drop-down list. The Expression dialog box displays. Using the drop-down lists, create the
following expression:
Country + Chr$(13) + POPULATION / Area(Object, “sq mi”)
The Chr$(13) function adds a carriage return to the first line. Using the Label tool, click a country.
MapInfo Professional labels it with the result of the expression.
