I have a distribution of data that is shown below in image 1. My goal is to show the likelihood that a variable is below a particular value for both X and for Y. For instance, I'd like to have a good way to show that ~95% of values are below 8000 on X-axis and below 6500 on the Y-axis. I am confident that there is a simple answer to this. I apologize if this has been asked many times before.
plot1 <- df %>% ggplot(mapping = aes(x = FLUID_TOT)) + stat_ecdf() + theme_bw()
plot2 <- df %>% ggplot(mapping = aes(x = FLUID_TOT, y = y)) + geom_point() + theme_bw()
