[R] Help me with R plotting

[baptiste Auguié]

Hi, 


Try this,

robots <- data.frame(id=letters[1:20],
                     x=rnorm(20),
                     y=rnorm(20),
                     consumption=runif(20, 10, 100))

library(ggplot2)

ggplot(robots) +
  geom_point(aes(x, y, colour=cut(consumption, c(0, 30, 50, 100)))) +
  geom_text(aes(x, y, colour=cut(consumption, c(0, 30, 50, 100)),
                label=round(consumption, 2)), vjust=1, legend=FALSE) +
  labs(colour="consumption")

      
HTH,

baptiste
