- In the Label Style Composer dialog box, click the Layout tab. 
- Select a component from the Component Name list. 
- Change the Rotation Angle value. 
- Click OK. 
Rotation angles are dependent on the Orientation Reference of the label style: 
-  Label Orientation Reference set to Object. The rotation angle is measured relative to the X and Y coordinate system as defined by the anchor component direction. For example, if the anchor component direction is 45°, then the rotation angle is measured relative to 45°. 
-  Label Orientation Reference set to World. The rotation angle is measured relative to the world coordinate system (X direction = 0° and Y direction = 90°). 
-  Label Orientation Reference set to View. The rotation angle is measured relative to the current view (X direction = bottom of screen and Y direction = 90° from bottom of screen).
