That will change the size of the legend key, not the size of the aesthetics inside the legend. For that you need to use override.aes in guide_legend, as I previously suggested. Best, Ista It may do something like what you want with some tweaking. My quick and dirty example just applies the command to both legends. > > pl<-ggplot(dat1,aes(x=Importance,y=Performance,fill=PBF,size=gapsize))+ > geom_point(shape=21,colour="black") > pl + theme(legend.key.size = unit(2, "cm")) > > John Kane > Kingston ON Canada > > >> -----Original Message----- >> From: mike.conk...@gfk.com >> Sent: Thu, 31 Oct 2013 21:08:02 +0100 >> To: r-help@r-project.org >> Subject: [R] help with ggplot legend specification >> >> I am creating a scatterplot with the following code. >> >> pl<-ggplot(df,aes(x=Importance,y=Performance,fill=PBF,size=gapsize))+ >> >> geom_point(shape=21,colour="black")+scale_size_area(max_size=pointsizefactor) >> >> points are plotted where the size of the point is related to a metric >> variable gapsize and the fill color on the point is related to the >> variable PBF which is a 4 level factor.
