Hello Omer, If you want violin plots for different categories, I would suggest lattice solution. For start; https://www.r-bloggers.com/violin-and-boxplots-with-lattice-and-r/ Search terms: lattice, bwplot, panel.violin will help you find more examples. > > ggplot () + > > facet_grid (PARAMETER ~Wshed, scales="free_y") + > > geom_violin (data=merged, aes(x=Geo, y=RESULT)) > > > > I do not want facets, they crowd the information so it is unreadable.
