You could add size = log10_P to the aes() inside geom_point(). Untested code below. See also http://ggplot2.tidyverse.org/reference/geom_point.html
ggplot(mydata, aes(x = X, y = log10_P)) + theme_bw() + theme(panel.border=element_blank(), legend.position="top", axis.text=element_text(size = 8)) + geom_point(aes(color = Traits, size = log10_P)) Jean On Fri, Jun 16, 2017 at 9:33 AM, greg holly <mak.hho...@gmail.com> wrote: > Hi all; > > I am running the following ggplot codes.
