Hello everybody,
Using ggplot2 package, is there a way to force to stop the y-axis line
at a specified point ? (not using ylim because I want that some text
written using annotate() at the top of the graph is still shown).
Bellow is a simple example to show what I would like do:
Thanks a lot
Marc
library("ggplot2")
g <- ggplot()+
geom_point(aes(x=c(20, 29, 32), y=c(0, 0.4, 1)))+
scale_y_continuous(breaks=c(0, 0.25, 0.5, 0.75, 1))+
labs(x="Label for x axis")+
labs(y="Label for y axis") +
annotate("text", x = 25 , y=1.2, label="Text 1")+
annotate("text", x = 22 , y=1.0, label="How to stop the y-axis line
here !")+
geom_segment(aes(x=25, xend=25, y=0, yend=1.1), linetype=2)+
# This part is just to make it more nice
theme(panel.background = element_rect(fill = 'white'),
panel.grid.major = element_blank(),
panel.grid.minor = element_blank(),
plot.margin = unit(c(0.5, 1, 0.5, 0.5), "cm"),
axis.text.x=element_text(size=14),
axis.text.y=element_text(size=14),
axis.title.x=element_text(size=18),
axis.title.y=element_text(size=18),
axis.ticks.length=unit(0.3,"cm"),
panel.border = element_blank(),
axis.line.x = element_line(),
axis.line.y = element_line())
g
