Moritz,
Couldn't help myself and tried out the new v.area.thematic.
I very much like it, but there is something not working about the color
assignments. I tried the following, using the new NC GRASS demo data set.
GRASS 6.3.svn (nc_spm_07):~ > d.area.thematic map=censusblk_swwake
data=total_pop breaks='v.class map=censusblk_swwake column=total_pop
algo=std nbcla=4' colors=0:0:255,0:0:100,100:0:0,255:0:0 layer=1
bwidth=0 bcolor=yellow render=l
Two things are not correct in this command line:
- You need to use back ticks (`) and not single quotes (') aroung the
v.class command line.
- The example in the description.html was wrong: it should be v.class -g
so that you do not get the full v.class output, but only the shell style.
This should work:
d.area.thematic map=censusblk_swwake data=total_pop breaks=`v.class -g
map=censusblk_swwake column=total_pop algo=std nbcla=4`
colors=0:0:255,0:0:100,100:0:0,255:0:0 layer=1 bwidth=0 bcolor=yellow
render=l
