Hi Lene,
thank you for your help. Of course I knew classification. In the meantime I realized that my problem doesnt require the usage of data-defined styling but just simply classification. Sometimes its too easy to first see solution. Sorry for time wasting. Julian Von: Lene Fischer [mailto:[email protected]] Gesendet: Mittwoch, 23.

For Example: Polygonlayer with 3 objects. Object 1 and 2 have value1 in the column value and object 3 has value3 there. Now QGIS should fill polygon 1 and 2 in one color and polygon 3 in another. I tried it with data-defined propertiesàcheck color and choose value for field but then all polygons are black. Do I have to write a special expression? Thanks for help! Regards Julian
