I have 30 line thickness classes. Yes I can give to each Symbol a specific Color, but the Color differences between the classes will not exactly be the same. How can I give to these 30 classes an individuell Color that matches a Color ramp?
I could also in the first place apply a Color ramp, make 30 classes, and then Change the line thickness individually for each class. But when I want to Change the amount of classes, I have to Change again everything manually.
How can I both apply a Color ramp and different line thicknesses in an automatic way?
