Hi Paul!

I had a similar problem few months ago.

I guess you actually have to modify the legend of your elipses by using "Unique Symbol - Polygon" instead of  "Unique Symbol - Point", in the simple edition mode.

OrbisGIS specialists will correct me if I am wrong.

Dear quentin,

GOOD job, you are right,it's the problem of the legend,and do you know how to circle a big area according one point(one place)?
like a big round circle a point,and I know the r=100 and the point?


Best regards
