I know QGIS has a feature to make labels size dependant from an attribute:
The problem is that I don't know how to choose a maximum size or even a size variation-scale. It makes the size proportional to the values of the chosen attribute, which sometimes makes the lables too big (or too little):
I've tried to use the "expression" labeling (for example using logarithms), but I don't know how to make the maximum and minimum be less "extreme".
Is there a way (maybe through an expression) to make the size of the labels more visual-friendly? Something to make those labels "less proportional" to the attribute.
