I am new to QGIS.
I have a layer that, among other fields, has two with the structure below:
id | Class 1 | 2 2 | 1 3 | 2 4 | 5 5 | 6 6 | 2 7 | 3 8 | 4
The id column represents specific regions of a layer and class has values ranging from 1 to 7. I would like to differentiate the regions based on the value of the layer column. I am trying to do it through the function editor, but I am not able to reference the columns in the code.
How do I do this task?
