[Qgis-user] Drawing over lapping polygons from postgis vector data table.

[Dave Potts]

Hi

I am trying to display the results of a spatial analysis, the return 
form is a set of polygons of increasing size. All located on top of each 
other.  I want to draw it, so it looks like a target, but all that 
happens is that the largest polygon is drawn last which blocks out all 
of the others.  Is there an easy way of display the result?

I can not see any way of using an outside function so that the largest 
polygon would be drawn firsts with the next polygon drawn on top of it.

Since its an import from a postgis table every does have an unique id.

regards


Dave.
