[Qgis-user] Proportionnal point for polygon

[Yves Jacolin (free)]

Hello,

I am trying to make proportionnel point for each polygon of my map. Polygon 
layer is swiss' canton and my attribut field for the proportionnal value is the 
population in 2010 (dbf joins with the canton layer).

I choose "graduate" style, change the symbol to "centroid fill" and create the 
class. My point symbol are not proportionnal.

I put all of my data here: http://download.qualitystreetmap.org/osm/Suisse/

Files you need for testing:
* project/prop_point.qgs
* population_2006-2010.dbf
* admin_level/pays/pays.*
* admin_level/regions/regions.*

I ma using QGIS 1.7.2.

Finally, is it possible to define a transparent border for such ponctual symbol 
with a large width (5 px for example)?

Thanks,

Y.
