Comment (by jamesp670):

 For my part, I'm happy that d.vect.thematic2 in addons is potentially
 a solution.  It would be better if the built-in C version implemented
 these features from Grass 6.4.

 Moritz asked me to "file enhancement requests against that module for
 the different feature you would like to see".  I looked at doing that
 but I do not see any better way to file the feature request.  There
 isn't a component that is relevant more detailed than "Display" which
 I chose for the original bug.

 The larger architectural issues raised by Moritz are beyond my ken.
 His mailing list post at 072918.html doesn't seem to address the needs
 of a psmap user making a thematic map.

 So that's my point of view three years on.  More details on how to
 refile the bug would be welcome.  I am always glad to cooperate with
 this amazing dev. team.  Thank you for what you do.

 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:

 1. 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).
 2. To automatically generate psmap commands, especially for the legend,
reflecting the breaks and colors automatically assigned in step 1.

 UPDATE

 Moritz Lennert: wrote in reply to this issue:

 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 [1]).

 The old script module is still available as an addon under the name
 d.vect.thematic2 [2] and should be easy to install.
