Hello,
I transfered data values of 66 plots from R to GRASS using sites.put() and
plotted their values via the v.bubble command on the background of a raster
image.
I wonder if a pie chart or bar chart is as well available this way.
I looked for d.vect.chart but that seems to be only available in >5.1.
Is it due to the limit of one variable/vector in 5.0.x?
I there a way to plot a pie/bar chart of vector values (8 variables) in 5.0.2?
thanks in advance, cheers Martin
The best way is to use the interface with R. See Marcus' short course notes for details.

Hello,
I suppose you mean library(GRASS), what you have to use when R shall run
inside GRASS.
My problem is not the interface with R, that works fine so far but the chart
option in GRASS 5.0.2.
I could in R do rast.get() for my rastermaps and display them in R and the
barchart wouldn't be a problem but R slows down significantly when trying to
handle a data frame of a few 100 000 values, therefore I would like to keep
the whole rastermap in GRASS and only transfer the values for the barchart
into GRASS and display the charts there.
Or I upgrade to 5.1. but as long as it is not meant for productiv use, I
prefer to keep 5.0.x.
cheers, Martin

that doesn't mean you can't use it for production use! 
nothing to be afraid of, it works. You can install both 5.0.x and
5.7 (ie 5.1) on the same machine and run each when you need it.

If you can get it into a raster layer:
d.histogram style=pie

well, I installed 5.7 and it looks promising!
d.m does not work due to some libproj.so.0 error (I pasted it below if this
error is not kown yet) but I could get a glimbs of the new grass look (until
this nice map disappeared and left some error messages ,-) ) .
Could it be that the vector support is not implemented yet? d.vect does not
show up with vector files and doing it by command line prompts that there are
no such vectors.
but d.vect.chart ctype=bar is what I am looking for and it would be awesome to
get it running.
but great work! despite that I have to learn some new commands ,-)

Make sure your libproj.so.0 is installed in a directory your system
searches for shared libraries in, e.g. add this directory to your
LD_LIBRARY_PATH environment variable or on Linux to the list in /etc/ld.so.conf
and run ldconfig.

wow! that looks good - nice map display handling.
the problem with libproj.so.0 worked pretty straight forward in debian
testing/unstable. installing proj and running grass57, nothing else. thanks
for the info.
