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

use the 'where' clause
Experiences with this matter?
If you want to see an example, just run d.vect.thematic and tell it to create a ps.map file (if you're using GIS Manager, just fill in the 'Name for ps.map instruction files' text field.
Use the 'label' clause to create a label (d.vect.thematic does automatically) and the vlegend to display your classes in the legend.

Hi Moritz,
thank you very much! This helps..
