How do I remove all space around the plot area?
Sample data
dfr <- data.frame(x=factor(1:5),y=c(3,5,4,2,4))
ggplot(dfr,aes(x,y))+
geom_bar(stat="identity")
I tried as below, but there is still space on left and bottom. Bg border colour added to visualise edge.
ggplot(dfr,aes(x,y))+
geom_bar(stat="identity")+
labs(x="",y="")+
theme(axis.ticks=element_blank(),
axis.text=element_blank(),
plot.background=element_rect(colour="steelblue"),
plot.margin=grid::unit(c(0,0,0,0),"cm"))
