Retain exact y values when using geom_beeswarm(method="center")

[jbengler]

Hi @eclarke,

thanks for this great package!

I noticed that geom_beeswarm(method="center") nicely centers the points. However, it also changes the y position resulting in binned and thus "inaccurate" y values.

Without method="center" correct y values are displayed

With method="center" y value position is "inaccurate"

I would love to have the best of both worlds: centered points that faithfully recapitulate the real y value.

I know that this is possible in plotting tools like Prism, which does a great job in positioning points. However, a ggplot version of this would be fantastic!

Hi @jbengler, could you provide a reproducible example I can test against? Just the code and dummy data would be sufficient. Thanks!

Hi @eclarke,

thanks for looking into this!

If I run the two examples below, I see the y-position of the lower dots changing. As if method="center" would apply a y-axis binning.

tibble::tibble(score = c(23,24,32,37,45,150)) %>% 
  ggplot2::ggplot(aes(x = NA, y = score)) +
  ggbeeswarm::geom_beeswarm(cex = 3, method="center")

tibble::tibble(score = c(23,24,32,37,45,150)) %>% 
  ggplot2::ggplot(aes(x = NA, y = score)) +
  ggbeeswarm::geom_beeswarm(cex = 3)
