Using ggplot2 geom_path() in a grouped variable

Hello,

I am not understanding the problem.
With a made up dataset everything seems right.

set.seed(1234)    # make the results reproducible
n <- 10
data <- data.frame(Pretrend = rep(1:10, 2),
                    Outcome = 1:10 + rnorm(2*n),
                    Control = rep(1:2, each = n))


library(ggplot2)

p <- ggplot(data, aes(Pretrend, Outcome, colour = factor(Control))) +
   geom_point() +
   geom_path() +
   labs(x = "Date", y = "Cases", title = "Intoxication Cases")

p


I have changed the plot name because 'plot' is the name of a base R
function.

What is the problem with the graph above? Is that what you were looking
for? (Or similar.)


Hope this helps,

Hi! I am trying to make a scatter/path graph in one variable that is
divided in two groups (variable Control), but when I use the
geom_path() option, the line continues from the group one to the group
two, and I wasn't able to avoid it.I need the path draws over the
group one and then draws over the group two avoiding the connection
between the last value of group one and the first value of group two.

This is my code

library(ggplot2)
plot <- ggplot(data, aes(Pretrend, Outcome)) + geom_point()
plot + geom_point(aes(colour=factor(Control)))+labs(x="Date",
y="Cases", title="Intoxication Cases")+geom_path()

Could you please bring be some advice.
