Using label classes to label features from the same layer differently
- Click the Label Manager button on the Labeling toolbar.
- Click the layer in the Label Classes box for which you want to create label classes.
- Type a name for your new label class in the Enter class name text box and click Add.
- Uncheck the Default label class to avoid labeling some features twice.
- Right-click the new label class in the Label Classes list and click SQL Query.
- Click the operators to build an expression that identifies the subset of features you want to label.
- Click OK.
- Click the Label Field drop-down arrow and click the attribute field you want to use as a label.
- Click the buttons and drop-down menus to define the symbol and placement properties of your labels.
- Repeat steps 2 through 9 if you want to create additional label classes.
- Click OK.
You can use label classes to label only a subset of features in a layer. For example, you might label only cities with a population greater than 1,000,000.
You can specify a different label field, symbol, scale range, label priority, and set of label placement options for each label class.
Label classes allow you to use a different text symbol to label different types of features in the same layer. For example, you can label cities with a large population in a larger font than those with a smaller population.
