I am trying to make a boxplot filled by a binary variable, with a facet grid. I also want to have jitter on top of the boxplots, but without getting them confused with the outliers. In order to fix this, I have added colour to the jitter, but by doing so, they meld in with the already coloured boxplots, as they are the same colour.
I really want to keep the colours the same, so is there a way to add borders to the jitter (or is there a different way to fix the outlier problem)?
plot <- ggplot(mpg, aes(class, hwy))+
geom_boxplot(aes(fill = drv))+
geom_jitter(width = .3, aes(colour =drv))
# facet_grid(. ~some_binary_variable, scales="free")
