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. This works exactly as I want with the points varying in size
based on the metric and being color coded. I get 2 legends on the side of the
plot, one related to the size of the dot and the other showing the color
coding. The problem is that the dots on the color coding legend are so small
that it is impossible to discern what color they are. The dots in the plot are
large, so it is clear what colors they are, but the legend is useless. How can
I increase the size of the points in the color legend.
pointsizefactor<-5
