Timeseries with Categorical Y axis

Hello everyone,

I'd like to create a plot of two timeseries, in the style of a ridgeplot (see image). So instead of plotting a density, I'd like to plot two timeseries in the same plot, but have them not overlap. The timeseries only take on values of 0 or 1.

I've been playing around in R using just geom_line(), but with no succes. The closest I've gotten is with the code below.

Any tips are much appreciated.

library(tidyverse)
  
  df <- data.frame(
    g1 = rbinom(n = 50, size = 1, prob = 0.60),
    g2 = rbinom(n = 50, size = 1, prob = 0.60),
    time = 1:50)
  
  df %>%
    pivot_longer(1:2) %>%
    ggplot(mapping = aes(x = time, y = name, col = value)) +
    geom_line()

You should look into dygraph packagel i guess it might help you.

library(ggplot2)
library(ggridges)
set.seed(42)
d <- data.frame(
  x = rep(1:5, 3),
  y = c(rep(0, 5), rep(1, 5), rep(2, 5)),
  height = sample.int(2,15,replace=TRUE) -1
)

ggplot(d, aes(x, y, height = height, group = y)) + 
  geom_density_ridges(stat = "identity", scale = .95)

  geom_point() + geom_line()

This is very close to what I want.

Any way to get rid of the density stuff? Get rid of the filling in with gray?
Any way to add the the datapoints?

Thanks so much! That seems perfect
