[Qgis-user] labelling by attribute

Hi Luca,

You can find the images also in the online archives of the mailing list:
http://lists.osgeo.org/pipermail/qgis-user/2015-June/032464.html (scroll 
down to the bottom).

The issue with ArcGIS is that only a very small fraction of the devs and 
users has access to ArcGIS - so unless you can point to some public 
document that explains an issue or function (e.g. online version of 
ArcGIS documentation) there is not much value in pointing us to "the way 
ArcGIS" does it.

Greetings,
Andreas
