Setting the position for line layer labels

The Position and Offset determine the location of the label's anchor relative to the line, not the alignment of the label's text relative to the label's anchor. To change the alignment of the text, change its style (see Setting label representation).

In the Label Tool window, click the Line Options tab.
Under Vertical in the Position list, select whether you want the label to appear above or below the line.
In the Offset list, type or select the value representing the space between the line and the label. In the list, select the measurement unit.
Under Horizontal in the Position list, select whether you want the label to appear to the left, right, or in the middle of the line.
In the Offset list, type or select a value to adjust the position of the label. In the list, select the measurement unit.
