Hello, Thank you for this wonderful package. I was wondering if there is a way to add different customized text individually to each panel of the plot yielded by ggsurvplot_facet. I have tried : datHRa <- data.frame(hr = c("label= 4.3 (2.0; 9.0)", "HRa= 1.4 (1.0; 2.0)", "HRa= 2.2 (1.7; 2.7)", "HRa= 2.0 (1.3; 2.9)"), x=c(4,4,4,4), y=c(0.57, 0.57, 0.57, 0.57))

First case

facplot+ggplot2::annotate("text",x=4, y=0.57, label = list(c("HRa= 4.3 (2.0; 9.0)", "HRa= 1.4 (1.0; 2.0)", "HRa= 2.2 (1.7; 2.7)")), size = 4)

Second case

facplot+geom_text(data = datHRa, mapping = aes(x = x, y=y, label=hr))

Where facplot is the plot object created by ggsurvplot_facet with ncol=2, nrow=2.

Actual behavior

Both of the results (first and second cases) are weird, all the annotations are displayed at once at each coordinate and repeated identically for the 4 panels in the plot.

Expected behavior

What I wanted was one annotation per panel at the given coordinate. The annotations are different for each panel. Like in this example with ggplot dat_text <- data.frame( label = c("4 cylinders", "6 cylinders", "8 cylinders"), cyl = c(4, 6, 8), x = c(20, 27.5, 25), y = c(4, 4, 4.5) )

p + geom_text( data = dat_text, mapping = aes(x = x, y = y, label = label) )

Steps to reproduce the problem

I am sorry I could not share the original data.

Hello Antoine,

maybe the following code snippets help. However, I am not sure, if is intended use of the survminer package.

library('survival')
library('tidyverse')
library('survminer')

text_to_add <- 
  tribble(~ sex, ~ text, ~ x, ~ y, 
          0, 'Some text', 1000, 0.1,
          1, 'Some other text', 1000, 0.1)

fit <- survfit(Surv(time, status) ~ sex, data = colon)
gg <- ggsurvplot(fit)
gg$plot + facet_wrap(vars(sex)) + theme_gray() + 
  geom_label(aes(x = x, y = y, label = text),
             text_to_add, inherit.aes = FALSE)

If you want to avoid the change of the color and suppress the legend:

gg <- ggsurvplot(fit, palette = c('black', 'black'))
gg$plot + facet_wrap(vars(sex)) + theme_gray() + 
  geom_label(aes(x = x, y = y, label = text),
             text_to_add, inherit.aes = FALSE) +
  theme(legend.position = "none")

unnamed-chunk-7-1

It seems a bit hacky to me, but maybe it works for you.
