It would be nice if one could do multiple parallel classifications for controlling different visual variables.

The classification of on attribute controls the fill color, the classification of a different attribute controls the stroke color, and the classification of a third attribute controls the stroke-width.

The advantage would be that one has to deal with fewer classes when comparing the the traditional rule-based renderer or when combining all attribute combinations into a single attribute.

The legend would have to be revised though, as to show only the aspects the attribute is controlling.

Is this now covered with the data defined symbols?

  • Target version set to Future Release - High Priority

The rule-based renderer, the data-defined symbology and expressions certainly help to cover these cases. But it is still very time-consuming, esp. when a lot of classes are involved. For QGIS >2.0 we should discuss a better UI that help to deal with classifications involving two or more fields.

  • Resolution set to worksforme
  • Status changed from Open to Closed

I am closing this, because I think that our symbology system is now powerful enough to handle the cases I have.
