[GRASSLIST:37] how to load data into d.vect.thematic ?

[Philipp H. Mohr]

Hello,

I have tried to use d.vect.thematic, but I ran into a few problems.
I load my data in with:

        cat grass.in | v.in.ascii out=mypoints3 x=2 y=1 cat=3 columns='cat int, x double, y double'

I can draw the vector mypoints3 without any problems. But when I try to
display this vector with:

        d.vect.thematic map=mypoints3 type=point column=cat themetype=graduated_colors themecalc=interval layer=1
        icon=basic/circle
        size=5 maxsize=20 nint=4 colorscheme=blue-red pointcolor=255:0:0
        linecolor=0:0:0 startcolor=255:0:0 endcolor=0:0:255
        monitor=x0

I get the ERROR: No such column [cat].
Could some one please tell me how to read the data in so that it can be
used with d.vect.thematic.

Thank you very much.
Regards,
Phil
