Michael,
Could you please answer these two questions?
1. What is option breakpoints for?
All that is in the manual:
breakpoints=string Break points for custom breaks option. Separate values by
spaces. (0 10 20 30 ...)
is not informative for me. Might be that for some others too.
2. Why GRASSRGB for areas only? Could it be extended to lines and points?

Yes, it is on the list of things to do, along with GRASSRGB support in
ps.map.

Maciek,
1. All the thematic options calculate 'breakpoints' where the color change
in the thematic map: at a set of regular intervals (the number of intervals
defined by the user), 2 standard deviation units around the mean, quartiles,
and custom. The custom option just lets you define manually where the color
changes rather than having it determined by an algorithm (as it is for other
3 options).
2. You can put values into the GRASSRGB column for all vector types.
Currently d.vect only displays colors in this column for areas. According to
Hamish, this is being extended to lines and points.

Thanks for explaining this. Could it be elaborated similarly in the manual
(and include a note you are talking about options "themecalc" and "nint").
2. You can put values into the GRASSRGB column for all vector types.
Currently d.vect only displays colors in this column for areas. According
to
Hamish, this is being extended to lines and points.
Great, now I see. But manual says "Thematic colors can be uploaded to a
GRASSRGB column for later display (areas only) ...". This made me think it's
due to d.vect.thematic itself. I think this sentence should be changed to
avoid such missinformation.
Thanks
Maciek
