[bug] wrong limits in scale_y_continous for lines plot drops data points

[ido]

Hi,
when doing a line plot and setting limits that exclude some data
points the line gets broken.
example:

library("ggplot2")
values <- data.frame(pos=1:7,y=c(1,1,1,5,1,1,1))
p <- ggplot(data=values,aes(x=pos,y=y)) + geom_line() +
scale_y_continuous(limits=c(0,4))
p

I would have expected to see a line going up and down again without of
course seeing the tip.

best,
ido

Hi Ido,

This isn't a bug, it's the way scales work. You probably want +
coord_cartesian(ylim = c(0, 4))
