I have a hierachical List of attributes e.g. column (1) S (2) SD (3) SD0 or (1) A (2) AN (3) An1 etc. So there is one S with several SD s and several SD0 in the attribute table. When I display column (3) I wonder if there is an automatic way to set the colours in a stacked way i.e. all S different grey colours all A different blue etc. All I could find was the rule based way but then it is still a lot of work because there are so many types in column 3. Is there a way to use the other columns, in my case for example column 1 to classify?
Thank you for help!!
