I want to color a vector map. I’m just trying it with some test maps from the North Carolina demo set. I used the ‘manage color rules interactively’ dialog in the GUI and am using a version of GRASS 7 compiled on 1 November.
Is there no way to use a character column for colors? Even when I use a numeric column (e.g., the column “pumpers” in the firestations vector points map), the OK, apply, and preview buttons remain greyed out after I have filled out the table with values and colors. I’ve tried each of the integer values in the column and using the min and max values only. Yes, each of the table lines is checked. I thought that maybe this only works for area maps. But I have the same problems with them. (I tried the geology map). Clicking the “add column” button does nothing AFAICT I also tried the v.colors approach. I was able to do everything (no greyed out buttons). But no colors either. So what am I doing wrong? Making colored thematic maps is a pretty basic and important function. I didn’t try the thematic map layer because I wanted to do points too and it only does areas. Michael ______________________________ C.
