A. Since PC-ORD version 4.21 you can plot the row names from the second matrix, instead of getting those names from the graph file. You can use this facility to assign ANY labels you wish, to be included in the ordination. One application would be to give text names to groups, as you suggest. First create a second matrix with row names that reflect group categories and open this matrix as the second matrix in PC-ORD. Assuming you already have done the analysis and have a graph file, open the graph window. Select preferences in the menu and then select Labels From Second Matrix.
