I want to create a lollipop chart with three dots, which are connected with two lines, but anyway it doesn´t work: I always get a lollipop chart with just two dots.
My data:

My syntax:
ggplot(A_al) +
geom_segment( aes(x=x, xend=x, y=value1, yend=value2), color="blue") +
geom_segment( aes(x=x, xend=x, y=value2, yend=value3), color="blue") +
geom_point( aes(x=x, y=value1), color=rgb(0.2,0.7,0.1,0.5), size=3 ) +
geom_point( aes(x=x, y=value2), color=rgb(0.1,0.2,0.7,0.5), size=3 ) +
geom_point( aes(x=x, y=value3), color=rgb(0.7,0.1,0.2,0.5), size=3 ) +
coord_flip()+
theme_ipsum() +
theme(
legend.position = "none",
) +
xlab("") +
ylab("Value of Y")
What am I doing wrong?
