integrating textpath with stat_halfeye

[yonisidi]

I am trying to use {geomtextpath} to label different parts of a distribution visually and am having trouble figuring out how to blend the two packages together.

i am using stat_function as my solution in with the geom set to textpath.

any ideas how i can achieve this? thanks!

  plot_tbl <- tibble::tibble(
    dist = "lnorm", 
    label = c('>=3', '>=4',  '>=6', '>=8'),
    logmean = c(log(7),log(9), log(12), log(18)), 
    logsd = log(3.5)
  )

  plot_tbl |>
    ggplot() +
    ggdist::stat_halfeye(aes(
     y = factor(label), dist = dist, arg1 = logmean, arg2 = logsd,
     fill = after_stat(x < 6)), show.legend = FALSE) +
    stat_function(
    aes(y = '>8'),
      geom = 'textpath', 
      fun = dlnorm, 
      label = 'aaa',
      size = 5, 
      vjust = -0.2, 
      hjust = 0.1, 
      args = list(meanlog = log(18), sdlog = log(3.5))
    ) +
    scale_x_log10(breaks = 10^seq(-5,7, by = 2))

Yeah this is hard --- would probably need something like #217 so that thickness values could be translated into y values for that geom.
