I am trying to plot count v/s month
ggplot(dat, aes(x=month, y=count,group=region)) +
geom_line(data=mcount[mcount$region == "West coast", ],colour="black",stat="identity", position="dodge")+
geom_point(data=mcount[mcount$region == "West coast", ],colour="black", size=2, shape=21, fill="white")+
theme_bw()+
theme(legend.key = element_rect(colour = "black")) +
guides(fill = guide_legend(override.aes = list(colour = NULL)))+
ggsave("test.png",width=6, height=4,dpi=300)
But I want to order the months chronologically from Jan to Dec. How can I do this short of writing all the months out?
