[Qgis-developer] Weighted concentration renderer

[Paolo Cavallini]

Hi all.
If I select one field as a weight for the concentration renderer, to
remove it I cannot select an empty field, but I have to erase the
content by hand. A minor issue, but annoying nevertheless.
Am I missing something?
All the best.
