Suppose that we have a label file (Labels.dat) with the following format:
The first column is the X coordinate, the second column is the Y coordinate, and the third column is the label name.
E.g.
X,Y,Name
718099.47,4329198.13,P1
709826.94,4329920.53,P2
Import the label file, then RMC on that layer to display options as shown in Figure 1. These options are summarized in the Table 1.
Figure 1 Label layer: RMC options.
