[R] Date order question

[PIKAL Petr]

Hallo Thomas

Similar as suggested by Rui, you shall change your date to real date e.g. by

library(lubridate)
date <- paste(date, c(rep(2022,2), 2023), sep="-")
date <- mdy(date)

and you need to change also x coordinate in annotate.

ggplot(data, aes(x=date,y=PT,group=1))+
  geom_point(size=4)+
  geom_line()+
  geom_hline(yintercept =c(1,.60,0,.30,.25,.2))+
 
scale_y_continuous(label=scales::label_percent(),breaks=c(1,0.6,0,.3,0.25,0.
2))+
  annotate("text", x=date[2], y=.1, label="Very
Good",size=5,fontface="bold")+
  annotate("text", x=date[2], y=.225, label="Good",size=5,fontface="bold")+
  annotate("text", x=date[2], y=.28,
label="Marginal",size=5,fontface="bold") +
  annotate("text", x=date[2], y=.45,
label="Inadequate",size=6,fontface="bold")+
  annotate("text", x=date[2], y=.8, label="OOC",size=6,fontface="bold")+
  annotate("text", x=date[2], y=-.05, label="PT Not
Done",size=5,fontface="bold")

Cheers
Petr
