[GRASS-user] ps.map: add classified vector layers to map?

[Wolfgang Qual]

Hi list,
ps.map does a great job when printing maps without classification. But what is the best way to create a map with - let's say - two vector layers which should be divided into classes? I can only specify cat-values to be displayed or not, but not ranges of values for other columns (normally, I would say, I do not know the cat-values I would like to display, but e.g. the ranges of column1, column2).
Is there a good approach for this? Experiences with this matter? ps.map is the only possibility for me to produce high-quality-maps at the moment, as the printing functionality of QGIS is not developed that far.

I would really appreciate any ideas on this question!

Best,
Wolfgang
