please restore important thematic map features themetype, themecalc etc.
|Reported by:||jamesp670||Owned by:|
In the upgrade from GRASS 6.4.2 to GRASS 7, d.vect.thematic seems to have changed significantly. This is my tool of choice for making a legend for vector layers. For example, given a street map of lines called streetswm, and a column dacount indicating vehicles counted on a given segment, and with a monitor open, the simplest but still very useful d.vect.thematic command is:
d.vect.thematic map=streetswm@PERMANENT type=line column=dacount \ \
themetype=graduated_colors themecalc=interval nint=8 \ \
colorscheme=blue-red psmap=testthem2 \
In 6.4.2, that outputs both the legend and a nice thematic map using psmap syntax.
To be clear, I am looking for two separate features:
- To automatically generate breaks and assign colors to them. I just say "gimme 8 intervals in the blue-red" and I get out intelligence like "text 14% 54% 632.339 - 752.795 " (from testthem2\_legend.psmap).
- To automatically generate psmap commands, especially for the legend, reflecting the breaks and colors automatically assigned in step 1.

You are right that the C-module version is less feature-rich in some aspects than the original script version. Please file enhancement requests against that module for the different feature you would like to see (altough discussions are ongoing on whether this module should actually continue to be developed or not, see ).
The old script module is still available as an addon under the name d.vect.thematic2  and should be easy to install.
