[Qgis-user] Size of symbols in legend

[Julian Burgos]

Hello all,

Perhaps this is a basic question, but after doing my homework I could 
not find a way to do this.
I have a map with vector data (points) in which the area of the symbols 
are scaled to a particular feature of my data (i.e. like a bubble 
plot).  Now I am using the Print Composer and I´m trying to add a legend 
with a set of 3 or 4 symbols of decreasing size and their corresponding 
value.
Any ideas on how to do this?
Thanks!

Julian
