Is it possible to make this graph with ggplot, ordering the graph by the variable "t" in ascending order, distinguishing each "t" according to status (black or white circle, it can be another marker...) and if possible the variable "id " on the ordinate axis.
Id<- c(1,2,3,4)
t<- c(10,5,20,15)
status<- c(0,1,0,1)
df<- data.frame(Id, t, status)
Maybe you want something like this using geom_segment for the lines with geom_vline for the vertical lines. Using shape and fill aesthetics to fill the points with "black" and "white" per status. You can use the following code:
Id<- c(1,2,3,4)
t<- c(10,5,20,15)
status<- c(0,1,0,1)
df<- data.frame(Id, t, status)
library(ggplot2)
library(dplyr)
library(forcats)
df %>%
mutate(Id = as.factor(Id),
status = as.factor(status)) %>%
ggplot(aes(x = t, y = fct_reorder(Id, t, .desc = TRUE), shape = status, fill = status)) +
geom_point() +
geom_segment(aes(x = 0, xend = t, y = Id, yend = Id)) +
geom_vline(xintercept=c(t),linetype="dotted", alpha = 0.4) +
scale_shape_manual(values=c(21, 21), name = "shapes!") +
scale_fill_manual(values=c("black", "white")) +
scale_x_continuous(expand = c(0, 0), limits = c(0, 25)) +
labs(x = "", y = "Id") +
theme_bw() +
theme(panel.grid.major = element_blank(),
panel.grid.minor = element_blank(),
legend.position = "none",
axis.title.y = element_text(angle=0))
