[Qgis-user] Style menu: data-defined color

[Julian Schall]

Hi Lene,

 

thank you for your help. Of course I knew classification. In the meantime I
realized that my problem doesn’t require the usage of “data-defined styling”
but just simply classification. Sometimes it’s too easy to first see
solution. Sorry for time wasting.

 

Julian

Hi Julian,

It is called classification – se in the training manual
http://docs.qgis.org/2.2/en/docs/training_manual/vector_classification/index
.html

Hi,

 

maybe a simple question, but I couldn’t find the answer on my own: How can I
automatically change the color of polygons by the content of an attribute
table column?

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
